New Bike First Impression

Honda’s next generation ABS system graces its ‘09 CBR600RR not only as a safety aid but as a performance enhancement as well
Words Roland Brown Photography Honda

Three laps into my first ever test of an ABS-equipped super-sports bike, and it’s a weird feeling to be charging down the Losail circuit’s pit straight at over 230km/h, leaving my braking later… later… later… then grabbing the CBR600RR’s lever far harder than normal without a care in the world. Instead of folding its front wheel and spitting me off, the Honda simply sheds speed at a rate every bit as fierce as I managed on a non ABS-equipped CBR half an hour ago.

The bike feels reassuringly normal as it buries its front Bridgestone into the track, too, with none of the pulsing through the lever generated by conventional ABS systems. Perhaps there’s a little less fork dive than I might have expected. And the Honda stays remarkably stable as I brake and tip it into the tight right-hand bend, gently easing my grip on the lever as I approach the apex. That’s because I’m actually releasing both brakes: the ABS is contributing a touch of rear disc without even being asked.

If that scenario sounds almost like science fiction, I’d have said the same thing before riding the latest CBR600RR on its track launch in Qatar. Even braking hard on sand without a twitch of front tyre or heart rate, during yesterday’s test on the circuit’s car-park, didn’t prepare me for how effective — and how normal — Honda’s new anti-lock system would feel at speed on the track.

Honda is billing its Electronic Combined ABS, available as an option on both the 2009-model CBR600RR and Fireblade, as the world’s first anti-lock brake system for super-sports bikes. It’s certainly that, as well as the first “brake-by-wire” system that operates front and rear brakes electronically rather than mechanically. More importantly, it’s the first anti-lock system that is almost undetectable in use, and which has the ability to be a performance aid, even for fast and experienced riders.

Essentially this production-ready system is a more refined version of the prototype that Honda unveiled on a CBR600RR in August 2008. It works in a totally different way to conventional ABS set-ups, with their linked hydraulics. Instead, it centres on an ECU that monitors pressure in the brake lines, as well as the deceleration of both wheels. The ABS software decides how much pressure to apply to each brake, in order to maximise both stopping power and stability.

Unlike Honda’s previous Combined ABS, this system does not require special calipers. (The only difference is their gold instead of black finish.) It does add weight, though: 10kg for the CBR600RR and 11kg for the Fireblade, the difference explained by the fact that although the components are almost identical, they were harder to package on the larger-engined bike. Equally inevitably it also adds cost: roughly €1000, so more than conventional systems.

Some of the system’s benefits quickly became clear in the first day’s test at the Losail car-park, where we got to try both bikes’ stopping abilities on dry tarmac, wet tarmac and a thin coating of sand, in a dummy panic-brake from about 80km/h. Even the dry test was an eye-opener, as the Hondas stopped hard and skid-free, with none of the normal lever-pulsing (the software just doesn’t work that way). Both were stable, too, although the Fireblade’s rear end moved around slightly, without ever threatening to develop into a stoppie.

Grabbing a handful of front brake on a wet or sandy surface was even more impressive. The ABS seemed to slow the CBRs — using both brakes, whether the handlebar lever, foot pedal or both were operated — significantly harder than other ABS-equipped bikes I’ve tested in similar circumstances. The Hondas’ relatively light weight was doubtless part of the reason for that. But so too was the system’s sophistication, including a sensor that reacts in six milliseconds — four times faster than the VFR800F’s equivalent.

That test was very promising but it was next day on the circuit that revealed what a leap Honda has made. I began on the CBR600RR, which has gained a few non braking-related tweaks for 2009, as well as having its front calipers upgraded to Fireblade-style monoblocks. Revised pistons, cylinder head and exhaust silencer contribute to a slight torque increase between 8000 and 12,000rpm. Peak output remains 120bhp at 13,500rpm.

The titanium exhaust also has reshaped downpipes and a new Fireblade-style power valve, and is slightly lighter. Along with the new calipers, that helps reduce kerb weight slightly — to a claimed 184kg for the non-ABS model. The reshaped fairing lower is claimed to smooth air flow and thus aid stability, though the change is possibly more to do with hiding ABS parts. Clear, oval indicators and new graphics also freshen up the look.

Those Tokico monoblock calipers are the most significant addition, and helped ensure that even the non ABS-equipped CBR that I rode first was seriously well braked. It was quick and sweet-handling, too, as was to be expected, screaming to its 15,000rpm redline through the gears, and carving through Losail’s succession of fast right-handers with typical poise and control, aided by the grip of Bridgestone’s race-compound BT003 rubber.

It’s hard to know whether its new brake allowed the CBR to stop notably harder than its predecessor, but it certainly shed speed mightily rapidly at the end of that pit straight, and with plenty of feel at the lever. Honda’s new world Supersport champion Andrew Pitt, who’d just finished back-to-back testing with his old bike, thought the new calipers’ main benefit was improved steering response due to theirreduced weight.

Before riding the CBR I’d expected the difference between standard and ABS-equipped bikes to be much more obvious, so I was amazed to find the new system not just working but doing so in a totally unobtrusive way. I could come flying towards a turn, then squeeze the handlebar lever either as hard as I would normally, or purposely hard enough to lock a typical front wheel. In either case, the bike’s response was identical: hard, smooth, controllable stopping.

Andrew Pitt 2008 World Supersport champion “I’m really impressed with the ABS. I thought riding round a circuit it would feel very different to a normal bike. But it doesn’t. The ABS makes the bike much more stable into a turn, thanks to the back brake — I’m getting the benefit of braking without actually using it. You can trail brake quite a bit: if you’re going to just miss the apex of a turn, you can touch the brake lever and it adds bit of rear brake to help you turn in. Before I tried ABS I’d have said there was no need for it, but now I’m quite convinced it has a future in racing. Especially in the rain. It does take away something from the rider; in that way it’s just like traction control. But it’s a clever system that will stop a lot of crashes.”

Feel through the lever was normal, as was the bike’s response as I eased off the brake into the turn. (Braking too hard into the bend would cause a crash in the normal way.) But the Honda’s advantage was not simply that it prevented the wheels from locking, because the ABS system’s ECU also works to keep the bike as stable as possible by distributing braking force through both front and rear wheels, when either the handlebar lever or foot pedal is operated.

Like many riders (including some professional racers) I never use the rear brake on a racetrack, due its relatively small benefit compared to the front, the risk of locking the rear wheel, and the difficulty of dividing my concentration between front and rear. But when I squeezed the Honda’s handlebar lever, the ABS computer sneakily and efficiently added a small but significant (and lock-free, of course) bit of rear brake that reduced the bike’s fork dive, and helped keep it notably stable on the way into the turns.

Less welcome was the fact that because the CBR didn’t dip at the front as much as normal under braking, it needed a touch more steering input to make it change direction into the turns. Reducing the forks’ compression damping slightly could probably have sorted this, given a bit more time for fine-tuning. The system’s other disadvantage, apart from cost, is the 10kg weight penalty. But the extra kilos are located very centrally, and I couldn’t detect any detrimental effect on the handling.

In case this all sounds too positive, the test did have one flaw: the ABS we all tested in Qatar wasn’t the standard system, but had been modified slightly to allow for the soft-compound Bridgestone BT003 tyres. Like some other sticky tyres, these are slightly wider than the BT015s (or Dunlop Qualifiers) with which the CBRs will come as standard. This effects the way the ABS works.

---

 

Honda therefore fitted the testbikes with slightly modified ABS ECUs, similar to the programmable ECU that will be available as an accessory. “It is possible to use the standard ECU with race-compound tyres, but the ABS performance is not 100 per cent,” said engineer and test rider Tetsuya Kudoh. “It’s maybe 95 per cent — the ABS might activate slightly earlier.”

Given that most riders serious enough to use these bikes on a racetrack will want to fit sticky rubber, that is surely a distinct disadvantage. After all, someone who has just paid extra for ABS won’t be happy about having to spend more on a kit ECU. Honda doesn’t offer the option of disconnecting the ABS, either, although simply unplugging one of its wires would disable it and leave the standard brake system in place. (Some riders might prefer to do this for track days anyway.)

That is presumably what Honda had done to the Fireblades we rode immediately after lunch, though they wouldn’t confirm this. The format was the same as with the 600RR, so before riding the ABS-equipped Blade we had a session on a bike with the anti-lock deactivated. The Fireblade is unchanged for 2009 apart from new, clear oval-shaped rear indicators and minor bodywork revisions to cover the ABS parts. Predictably enough, the Repsol-liveried bike ripped round the circuit with the blend of smooth power, grunt, agility and stopping power that won so many comparison tests last year.

Back out for the second session with ABS reconnected, the system was every bit as impressive as it had been on the smaller CBR. The Fireblade still braked eye-poppingly hard, and it was an eerie feeling to sit up at the end of the straights and squeeze the lever, knowing that there was no chance of locking up the front wheel. Once again the stability provided by the ECU-triggered rear disc was useful, though the Blade’s rear tyre still waved around slightly under very hard braking. There was a bit more weight transfer with the Fireblade than with the lighter 600RR. Although the ABS-equipped Blade needed slightly more steering input than the normal model, this was less pronounced than with the smaller CBR.

By the end of my second session I was leaving my braking slightly later than I had been on the non-ABS Blade, though this was possibly because I’d had more laps in which to fine-tune my markers as the bike catapulted down the Losail straights. Honda racers Andrew Pitt, Jonathan Rea and Leon Haslam reckoned they were braking at almost exactly the same place as on the standard bike. So did Martin Bauer, who won last year’s German Superbike championship on a Fireblade, and will defend his title on an ABS-equipped model this season if the regulations allow it.

“I think it will be possible to use the ABS, although the other manufacturers will be against it,” says Bauer. “Its performance will be very close to a non ABS bike, maybe half a second per lap slower in ideal conditions. But it would be very good in the wet, and you could find the limit very fast on the first lap. Over a whole race distance it might be faster because you would be less likely to make mistakes.”

Whether it’s a good idea to allow ABS in racing is another matter, and one that rule-makers in Germany and elsewhere will soon be discussing. Like traction control, anti-lock brakes remove a significant element of skill, and are likely to be resisted by many who prefer to see the rider in full control. The reduced opportunity for outbraking, once everyone is using similar ABS systems, could make for dull racing — though riding the ABS-equipped CBRs round Losail certainly wasn’t boring.

There are also those who won’t want ABS on the road, either because they prefer to be in full control, or because they believe the system will be a disadvantage in some circumstances. That was certainly true of previous ABS systems — but not, I think, of this one. Honda admits that a good rider can narrowly outbrake even this system after two or three attempts, on a dry surface. But an average rider’s braking distance is longer, even after several tries. And even the best riders take longer when the road is wet or gritty.

More importantly, on the road you don’t get a second chance. Honda’s technically brilliant invention worked better than I thought possible on the Losail circuit, without detracting from the thrill of caning the firm’s fastest super-sports bikes. But it’s on motorways, high streets and twisty back-roads that the system will show its worth, when it prevents a skid or allows a rider to avoid a hazard they would otherwise have hit. Whether or not you like the idea of anti-lock brakes, the verdict is clear: with the arrival of electronic Combined ABS, superbike safety has taken a significant step forward.

 

TVS takes an eco-friendly initiative with the new hybrid Scooty
Words Bunny Punia Photography Adhish Alawani

Apart from the usual crop of Indian and imported motorcycles, the recently held Auto Expo in New Delhi also had a range of electric two-wheelers on display from close to a dozen manufacturers. But no matter how green these little wheels may be, there is always that mental block we have with their overall performance and of course, their operating range. However, TVS had something out of the box as an answer to these typical shortcomings – a lineup of sparkling white Scootys on display. They were being used as official bikes and interestingly, they had a unique graphic pattern on the body hinting at something, well, green. Curiosity leads to questions and hence, we decided to get hold of a few officials and check out the latest on offer.

TVS have developed a hybrid variant of their bestselling Scooty scooterette. The body is the same as the new Streak albeit with the new graphics. However, see the scooter from the left and you notice the smart casing of the electric motor that has been configured to run parallely with the same 87.8cc four-stroke engine powering the original model. Once astride the vehicle, you also notice four different operating models clearly marked out on the speedometer console along with the battery indicator. The four modes, namely Engine Only, Electric Only, Hybrid Power and Hybrid Economy can be chosen via a button (which on the regular model serves as the electric starter) on the right handlebar. Here is a brief look at what the different modes stand for:

Electric Only:
For short trips and zero fuel consumption. The scooter runs solely on the electric motor power.

Engine Only:
When the battery level is very low, the scooter runs on this mode.

Hybrid Economy:
Both sources run as per the programmed strategy. Initially, only the electric motor is in operation and once the scooter goes over a programmed speed, say 25km/h, the engine starts functioning as well.

Hybrid Power:
Both engine and electric together for better acceleration from standstill.

Further, to make the most efficient use of the energy, this hybrid system charges the battery when the brakes are applied and utilizes this power whenever required. In addition, this two-wheeler conserves energy when the vehicle is stationary at a traffic signal or at a standstill by stopping the power source. Brilliant! TVS claims to have achieved a 30 percent reduction in CO2 emissions, 25 percent reduction of HC + NOx and most importantly, a jump of around 30 percent in fuel economy.

During our short riding session around Pragati Maidan, we found the system to work perfectly. Although, with my weight (equivalent to two typical lightweight damsels), the electric motor took its own sweet time gathering pace. However, with a single college going female on board, the hybrid Scooty should perform very well. The parallel system is being fine tuned further and though no pricing has been disclosed, we expect a premium of around Rs 10k on the base sticker price. At this price, you get the best of both worlds – low fuel consumption and lesser emissions while retaining the same performance.

The Pulsar 220 Streetfighter is Bajaj’s latest offering at the altar of speed. Pure, unadulterated speed
Words : Saeed Akhtar   Photography by Sanjay Raikar

Evolution is a wonderful phenomenon. The fastest and the smartest species outrun their friends and foes alike and survive; the slower ones make their way to the extinction bin. In the end, the winners shed the body parts that weigh them down, are too cumbersome or just plain unnecessary.

For many years, the Pulsar was the ultimate bike in the Indian market if you wanted a fair bit of performance without burning a hole in your pocket. But the relentless advent of newer and faster bikes saw the flagship 220 DTS-Fi going back to the drawing board for a much needed revamp. The Bajaj boffins chucked the fuel injection system and inserted one of the biggest carburetors ever fitted on an Indian bike – an UCAL UCD 32 Venturi unit. Agreed, it was a step back in technology terms, but the benefits of this move were multifold. The bike became cheaper, quicker and faster in one fell swoop. Even before most automotive journalists could lay their hands on this new bike, it had created a sensation with its ‘fastest Indian’ ad campaigns that inundated the media. The bike certainly lived up to its tag with a true top speed of 132.5km/h.

And now, Bajaj have launched a lighter and faster version of the same bike. Speculations about this bike kept rising steadily ever since it came to be known that the stylish ‘F’ logo on the faired 220 stood for, well, faired. The biggest change in the new 220 DTS-i is the absence of the half fairing and the projector lamp. In its place comes the same wolf-eyed bikini fairing headlamp that does duty on the rest of the Pulsar range – the 150, the 180 and the now discontinued 200 DTS-i. This single change has lowered the kerb weight of the bike from 152kg to 148kg and that alone is a significant reason for the new bike to deliver better roll-on times than its faired sibling. Since the metallic parts of the bike are done up in black, it now resembles the 180 and the 200 very closely. Other minor visual differences are the clip-ons from the 220. The new Eurogrip tyres at both ends have a deeper tread pattern that closely resembles dual-purpose tyres, but customers can still opt for the Zappers that have been standard on Pulsars so far.

Clip-on handlebars are now standard across the entire Pulsar range	wolf-eyed headlamp shaves off weight, but we still wish for a naked version	One of the very few indications that this one belongs right there at the top of the food chain

The instrumentation and build quality of the bike remains the same. One little overlooked feature on the new generation Pulsars is the inclusion of a handy air filter cleaning interval indicator on the LCD dash. The stainless steel brake hose at the front reduces the flex and improves the feel braking. The reduced weight meant that we already expected the Pulsar to accelerate faster than its sibling and test runs would surely have showed a marginal improvement. It was also more manoveurable and felt far easier to tip in corners, due to its decreased weight at the front. Sadly, this might not translate into better lap times or better handling in the corners. The massive front forks still have a tendency to dive under hard braking while the new tyres fail to inspire confidence in the rider. It is not quite grippy enough and you can feel the rear squirming uneasily.

However, what makes the new Pulsar an irresistible buy is the discounted price of Rs 76,370 (OTR, Pune) which makes it one hell of a bargain compared to its peers. The faired Pulsar 220 DTSi already boasted a gobsmacking price tag thanks to the exclusion of the fuel injection unit. And now, with the removal of the fairing and the projector headlamps, the 220 has just shattered the price barrier. Heck, there are quite a number of far smaller and slower motorcycles that cost more. For that price, you get a motorcycle that smokes the competition and plasters a grin on your face every time you take it out. Some prospective buyers might be put off by the all too familiar looks of the bike, but that should not be a deterrent to the true-blue enthusiast who wants nothing more than a bike that can squash the competition on the drag strip.

BMW R1200GS
It’s a classical GS experience. Half an hour ago I was cruising comfortably along a Spanish motorway; ten minutes ago I was scratching down a twisty, smooth surfaced back road with my boot-toes clipping the Tarmac. And now I’m standing up on the pegs on a gravel covered path through the arid Andalucian countryside, gassing the big boxer motor to send up a satisfying rooster-tail behind me.

This off-road excursion isn’t very ambitious or exciting; just a short dirt detour before it’s time to get back on the road and head back to our hotel. There again, most R1200GS owners’ globe crossing daydreams aren’t matched by reality. And that hasn’t prevented the amazing success of the dual-purpose boxer, which contributes more than half of BMW’s total two-wheeled production and has notched up almost 200,000 sales since being launched six years ago.

Both the GS and its heavy duty Adventure sibling have been updated for 2010 with a new version of the air/oilcooled boxer motor, incorporating twin overhead cams for the first time. The engine, which is developed from that of the HP2 Sport (and is shared with the latest R1200RT) keeps the traditional GS capacity of 1170cc and features four radial valves per cylinder.

Performance is increased to a peak of 110bhp at 7750rpm, 5bhp up on the old unit. The new motor revs 500rpm higher to 8500rpm. It’s stronger by several horsepower almost everywhere from 2500rpm to that limit, especially at 5000rpm and 6500rpm, where it’s about 10bhp more powerful. The exception is a distinct dip between those points, where the old engine (whose own dip is 500rpm earlier) briefly goes ahead.

This GS update is pretty much confined to that new powerplant. The exhaust has a new cable operated valve, plus reworked internals for the single silencer. There are a few other fresh details: restyled instruments plus brake and clutch master cylinders, larger locating screws for the adjustable windscreen and a new fuel gauge sensor.

Styling is unchanged except for four new colour options, and the red bike I chose looked good in its accessory hand protectors. Having always admired the GS’s tall, bird-like profile I was glad about that, but less impressed by the appearance of that new exhaust valve. The valve with its twin cables is fixed to the exhaust pipe low on its left, and the whole thing looks a bit messy and tacked-on.

My negative thoughts were banished as soon as I’d hooked a leg over the BMW’s tall saddle, and fired up the motor to unleash a notably louder exhaust note through the repacked silencer. After the mild mannered old GS, this bike’s harder, thrappier note — still a distinctive flat-twin bark — gave an instantly more aggressive image. The bike’s ability to pass emission tests presumably owes much to that valve, so all credit to it.

The aural accompaniment made me even keener to give the GS some stick as we set off from the launch base near Malaga in southern Spain, with a plan to follow the coast road eastwards to Motril before veering northwards onto the steeper, twistier roads of the Sierra Nevada. Even before we’d got out of town and reached the A7 coast road, it was clear that the new sound was matched by extra straight-line performance.

The improvement is not dramatic and was it not for the exhaust note, you might not even notice it unless you’d just climbed straight off the old model. But I’m sure I wasn’t imagining an extra spring in the boxer’s step as it charged forward in response to a tweak of the throttle. It pulled from 2500rpm without complaint, punched hard through the midrange, and generally felt lively and impressively flexible.

Just occasionally I was conscious of a slightly slow response in the midrange, at about the 5500rpm mark, where that torque dip occurs. But it certainly wasn’t a problem and there was always acceleration at hand even when the Bee-Em was loping along at a lazy 130km/h in top. If anything I was more conscious of the bike pulling with extra enthusiasm as its torque curve headed sharply upwards approaching 6000rpm.

The GS was happy to rev, heading towards that higher 8500rpm redline with only a touch of vibration. But apart from one top-speed blast —it managed 185km/h into a very strong headwind — there was no real incentive to work it that hard. I much preferred to short shift through the six-speed box, which worked very well except on a couple of later occasions when, wearing motocross boots, I struggled to get my foot under the lever.

Fuel economy doesn’t seem to have been hit by the four-valve layout either. The GS was drinking less than 7 litres/100km despite some pretty high cruising speeds (assuming the accessory onboard computer could be believed), giving a range of well over 250km from its 20 litre tank. That computer also shows remaining range, and is a useful accessory. But talking of electrics, I was slightly disappointed to find BMW have retained their old style indicator switches on each handlebar instead of fitting a conventional button on the left as they have with the R1200RT (and S1000RR).

 

Comfort is another aspect of the GS that’s basically unchanged, which is no surprise because it’s outstanding. The one-piece bar (which can be reversed for standing up riding off-road) and thick two-piece seat give plenty of room in conjunction with well-placed and grippy footpegs. And although short riders will struggle slightly with a standard bike whose seat height is adjustable between 850 and 870mm, the accessory lower seat and suspension combine to reduce this to a much more manageable 820mm. Can’t ask more than that, you shorties.

Unfortunately very tall riders aren’t quite so well catered for. The screen is more easily adjustable than ever, thanks to its bigger screws, and at its highest setting gave useful protection. But at 1.93m I had to crouch slightly to get out of the turbulence. BMW don’t recommend using the Adventure’s taller screen, which does fit, because the standard bike’s mounts aren’t as strong. But some riders do fit it and I’d be tempted to do the same.

One adjustment option that I was very glad of was the red bike’s Enduro ESA (Electronic Suspension Adjustment), the GS’s version of the push-button wizardry. Unlike the R1200RT’s new ESA II system, the GS’s can’t change spring rate. But the ability to substantially alter damping rates without even slowing down is arguably even more valuable on a dual-purpose bike, with its extra suspension travel.

If buying a GS, I’d certainly pay the extra for ESA which allowed me to select a Comfort setting that effortlessly soaked up road surface imperfections in town and on the autopista at the start of the ride. Then, when we reached Adra and swung north into the hills, a quick press of the ESA button firmed up both the front Telelever set-up and the Paralever rear end, making the bike tauter and more stable in the bends.

We had to take a diversion to miss some of the best roads due to landslides that made some of the Alpujarras mountain roads impassable even for the GS (let alone the RTs that we had in tow). But there are so many twisty, generally well-surfaced and almost traffic free roads in this part of Spain, that it was easy to be reminded of just what a sound handling bike the GS is.

Six years after the bike’s launch, I can still vividly recall my first few hundred metres on one, riding down the twisty hotel driveway on the launch in South Africa — and being amazed by how agile the 1200 felt, after BMW had shed 30kg from its R1100GS predecessor. There’s no weight loss this time, but that’s because at 203kg the GS is light enough to be very manoeuvrable, at least on the road. That wide handlebar gives enough leverage to allow easy direction changes despite the bike’s dual-purpose geometry and 19-inch diameter front wheel.

---

Bridgestone’s road-biased Battlewing tyres gripped well enough to make good use of the GS’s ample ground clearance (and later seemed okay off-road too). The BMW also stopped hard, helped by an optional ABS system that links front and rear wheels. Our testbikes were also fitted with ASC traction control. I can’t say I noticed it on the road, but it’s not a bad thing to have in reserve. Like the ABS system, it’s very simply disconnected for off-road riding (or for wheelies, which it prevents), by pressing a button on the bars.

I’d need more time to experiment with the traction control, but at least it’s one of the less expensive accessories our bikes were carrying. The ABS brakes and ESA suspension adjustment add considerably more; the handy heated grips and sweet little LED indicators add further to an already pretty expensive bike. At least its used values are famously high.

Given more time, it would have been great to have pressed the ESA button again to select off-road suspension mode and headed much further along some of the dusty tracks that criss-cross southern Spain. But it’s really the GS’s road going performance that is boosted by the new motor, and we were short of time. So after a brief play in the dirt, I was back onto the hard stuff, heading to the overnight stop at Mojacar.

We’d been riding pretty much all day on a wide variety of surfaces, but the GS had barely been stretched; its remarkable all-round appeal enhanced just a bit by its extra power and that bonus of a character enhancing soundtrack. The R1200GS will be getting a new rival soon, of course, in Ducati’s comprehensively revamped Multistrada. The Italian V-twin looks very promising, but it will have to be mighty good to match the old master.

R1200 ENGINE TECH

 

 

This new 1170cc motor is closely based on the dohc unit from the HP2 Sport, though it contains some differences including using two spark plugs per cylinder, like the previous GS, instead of a single plug like the Sport. Each pot’s camshafts are chain driven and operate four valves that are arranged radially, operated via rocker-arms and semi-hemispherical shims.

The cams sit horizontally, in line with the bike, giving the unusual arrangement of each cam operating one inlet and one exhaust valve. The cams have a slightly conical profile, to suit the radial layout. Valve lift is increased from the old GS engine, and valves are bigger: inlets up from 36 to 39mm; exhausts from 31 to 33mm. Pistons are redesigned to suit the new combustion chambers, but bottom end parts including crankshaft and conrods are retained.

The intake system is uprated with redesigned trumpets and larger manifolds (50mm diameter from 47mm). The new electrically controlled exhaust valve also helps allow the increased peak output of 110bhp at 7750rpm, 5bhp up on the old high-cam GS unit. Maximum torque is also increased, by 5N.m to 120N.m at 6000rpm. The six-speed, shaft drive transmission is unchanged except for a slightly taller final ratio.

R1200GS Adventure
The Adventure is a brilliant bike; no doubt about that. It’s also undeniably, unmistakably huge. At 890mm, its seat is 40mm higher than the standard GS’s, and there’s no option of lowered suspension. At 223kg dry, it weighs 20kg more than the standard model — and that’s before you start filling that enormous, 33 litre gas tank, let alone adding running lights, aluminium panniers and other globe crossing accessories.

Inevitably, this size sometimes leads to problems. One short guy on the launch loved the lowered stock GS but didn’t even want to ride its giant brother. I’m tall and had no trouble getting both feet on the ground, but still had to concentrate hard at a standstill. Once this bike leans more than a certain angle, you ain’t going to pull it upright again.

This latest Adventure gets an identical upgrade to the standard GS. Same new dohc radial-valve engine and same extra torque, which is arguably even more useful with that extra weight to shift. Like the standard model, it retains its existing chassis, complete with extra suspension travel. It comes with the hand protectors and aluminium cylinder head guards that are an accessory for the standard bike. It wears wire-spoked wheels instead of cast, with the option of knobbly rubber.

Given that the standard GS is an exceptionally tall, well-equipped, rugged machine with a very generous fuel range, you have to wonder whether many riders really need a more expensive, heavier and more unwieldy version with even more of the same attributes. Most people would undoubtedly be better off on the standard GS.

But there was undeniably something very special about sitting on that wide, comfortable seat, sheltering behind the more protective, similarly adjustable screen that allowed me near-silent 150km/h cruising (unlike any pure bred touring bike I can recall riding), and glancing down at a digital display that was showing I had more than 500km ahead before needing to stop for gas.

It was also inspiring to know that I could simply have turned off the road onto a dirt track, and kept on going almost no matter what got in the way – at least until I fell off and had to pick up the great brute, anyway. My short off-road excursion was fun, and for once I actually stayed upright, but the BMW’s size and weight were never far from my mind.

I spent my last blast on the Adventure back on the main road, thinking that it was simply the most complete, do-it-all bike I’d ever ridden; and that if I had to own just one bike for ever, this would be it. But I had to conclude that for me, as for so many others, it would be excessive.

Just as with the standard GS, the Adventure’s new engine makes a very good bike better still. But even if you’re fortunate enough to be able to afford a very substantial basic price that is sure to grow considerably with accessories, it’s important to be sure that this is a bike you really need and can use. The Adventure is up to the challenge. The question is: are you?

BMW R1200RT
The bike is new; the BMW touring experience is timeless. At a steady 130km/h on the motorway, I’m sheltered by a broad, adjustable screen. A relaxed riding position and heated seat add to the comfort. The flat-twin motor beats effortlessly down below. I glance at the digital instrument panel to find that the bike is averaging 15.3Kmpl, and will not require a fuel stop for more than 300km. Bring them on…

BMW has introduced so many totally different models of late, from middleweight parallel twins via mad naked fours to the insanely fast S1000RR, that it almost seems strange to be riding a new German bike of the old school: a fully-faired tourer with big fairing, boxer motor, shaft final drive and panniers; even if this RT has been updated for the iPod era with extra performance as well as a new sound system and numerous other tweaks.

It’s the engine that provides the main news. The air/oilcooled, 1170cc flat twin is developed from the HP2 Sport unit, and is identical to that of the latest R1200GS. That means it has twin overhead cams and four radial valves per cylinder and produces 110bhp at 7750rpm. That maximum output is unchanged from the previous RT’s, but the new motor makes more torque through most of the range and its 8500rpm limit is 500rpm higher.

With its broad fairing, standard fit panniers and those sticking out horizontal cylinders, the new bike looks subtly different but still very much an RT. New headlights and reshaped fairing nose give a sharper look, although the modernising effect is limited by the limited paintwork options. There’s a generous four to choose from, but all are variations of grey, with no colour to be seen. Maybe a bit too traditionally BMW.

The view from the rider’s fairly low seat is bang up-to-date, though, especially on the fully accessorised RT on which I spent most time. Between the two main analogue dials is a digital display that can show everything from average speed to the music selected on the MP3 player (or memory stick) that can be kept in a lockable compartment in the right of the fairing.

The right bar has buttons for heated grips and seat but it’s the left handlebar that gets complicated, at least on a fully loaded RT. As well as a conventional single button (at last!) for the self-cancelling indicators, this BMW has buttons for windscreen height, ABS, traction control, cruise control and ESA electronic suspension adjustment. Oh, and a rotating wheel to control the sound system, which also has an array of buttons on the fairing.

It was all a bit confusing at first inspection, but at least the RT itself is relatively simple. Inevitably the broad fairing makes the bike feel quite bulky, but the air/oilcooled twin-pot motor contributes to a dry weight of 229kg. That’s light by touring standards — in fact it’s 35kg lighter than Yamaha’s FJR1300, the lightest of the touring fours, and an incredible 171kg down on the 400kg figure of Harley’s Ultra Classic Electra Glide.

That lack of weight helped the RT feel reassuringly manageable when I climbed aboard on the launch in southern Spain, midway through a two-day trip shared with the R1200GS. At 820-840mm, the standard seat is low enough to allow most riders to get both feet down (and there’s an optional low seat that’s just 750mm). The new motor fired up with a distinctive boxer throb but sounded less throaty than the new GS, despite also gaining an electronically controlled flap on its exhaust.

Straight line performance was pretty similar, though. That 110bhp maximum is nothing special by big tourer standards, but it’s backed up by a broad spread of torque that gave effortlessly strong acceleration. The BMW happily pulled from 3000rpm out of the bends, as we headed west on the generally well-surfaced roads near Almeria, and always seeming to have the right gear in its smooth shifting six-speed ‘box.

There’s slightly more torque all through the range, except for at the very top. Such is the midrange performance that I rarely revved it near that new 8500rpm limit, although vibration levels remained low — perhaps a bit lower than the old pushrod engine’s. With a crisp response from the injection system, and plenty of punch at five or six grand, it was simpler and more satisfying to change up early and enjoy the BMW’s long legged character.

The RT’s new found grunt will be useful when it’s heavily loaded, and was welcome when we hit the A92 motorway. The bike was happy sit at a relaxed 120km/h plus in top gear and then delivered a burst of acceleration when its predecessor might have demanded a downchange. Comfort was as important as performance and predictably, the BMW scored highly, starting with a riding position that is unchanged but now incorporates rubber mounted bars and an adjustable gearlever.

The fairing and screen are both wide enough to give plenty of protection, in conjunction with the big, low set mirrors whose view was slightly obscured by my hands. For my money, an adjustable screen as almost essential on a serious tourer, and the RT’s is among the best. Being very tall I found it wasn’t quite high enough even when fully extended, and generated mild turbulence that disappeared if I crouched slightly, but most riders won’t have that problem.

After a couple of hours, I was enjoying the RT’s effortless distance eating ability, slightly annoyed that I couldn’t find anything worth listening to on the radio (which has 24 presets instead of the previous six) and that I didn’t have the necessary adaptor for an iPod. Having set out with my overjacket in one of the big panniers, and with no chance to stop, I was grateful for the bike’s heated grips and seat. Then we turned off the motorway, and the RT had a further chance to shine.

This bike has an updated, ESA II version of BMW’s electronic suspension system. This allows preload and spring rate, as well as damping, to be set with the press of a button, and also has a broader range of damping adjustment. The ability to adjust the spring, which will be useful when adding or removing a pillion or luggage, wasn’t needed on our trip. But when we reached a twisty road it was great to be able to firm up the RT’s handling by changing damping from Comfort to Sport mode, without even slowing down.

Within seconds, a bike whose suspension had been supple enough to absorb motorway imperfections became a much firmer, more responsive machine that was happy carving through the bends. The RT wasn’t as agile as the lighter, wider-barred GS boxer, but it could be hustled along pretty quickly, with the help of excellent Metzeler Roadtec tyres, ample ground clearance and powerful, ABS assisted brakes.

The RT was certainly taut, light and controllable enough to be fun, and to encourage spirited riding, on a twisty road — which is more than can be said of plenty of its heavier and no better equipped rivals. The ESA system is so easy to use that after a bout of back road scratching it was no problem to switch back to Comfort for pobbling through villages, over road repairs or speed humps. The ESA is not cheap, but I’d pay the extra every time.

The test bikes were also fitted with BMW’s accessory ASC traction control system, which was worth having just in case, although I didn’t notice it working. Back on the motorway heading towards Malaga, I put the screen back up, flicked the cruise control on, and got back to searching for a radio station. It’s tempting to dismiss some of these features as gadgets, but they certainly help make life more pleasant on a long trip.

And the important thing about the RT is that its basics are right too. Both panniers are big and easy to use, with space no longer wasted by a CD player, and the tank is designed to take a tank-bag. The 25 litre fuel capacity combines with the boxer’s efficiency — 7 litres/100km when ridden hard, with under 6 litres/100km possible — to give a typical range of 350km.

A pillion gets a broad seat and plenty of legroom, plus a switch to control their half of the accessory heated seat. There are countless other accessories, of course, from top-boxes and inner bags to chromed parts and additional power sockets. Most buyers will doubtless opt for several although the RT is not cheap, either in its basic form or in the more expensive SE model (which, depending on market, includes ESA, heated grips and seat, computer, cruiser control, extra socket and chromed exhaust).

Perhaps this grey BMW sometimes lacks a little excitement, in its performance as well as its paint schemes. But by the time we reached Malaga, the RT had done enough to suggest that it’s a very worthwhile improvement over its predecessor and a bike that makes that timeless BMW touring experience better than ever.

R1200RT TECH

The RT is powered by the same dohc, air/oilcooled flat twin engine as the updated R1200GS. Developed from the HP2 Sport motor, the radial eight-valve boxer is detuned to give a maximum of 110bhp. That’s an identical peak output to the previous RT (and 20bhp down on the Sport), but torque is increased from 2500rpm to the 7750rpm point at which maximum power is delivered.

Like the HP2 Sport motor, the new unit features chain-driven cams that are conically shaped to suit the radial valves, which are operated via rocker-arms. This engine differs by using two spark plugs per cylinder, like the previous GS, instead of a single plug like the Sport. The cams sit horizontally, in line with the bike, with each cam operating one inlet and one exhaust valve.

Changes from the old RT engine include bigger valves (inlets 36 to 39mm; exhausts 31 to 33mm), new pistons and reshaped combustion chambers. Bottom-end parts including the crankshaft and conrods are unchanged. The intake system is uprated with redesigned trumpets and larger manifolds (50mm diameter from 47mm). The exhaust gains an electronically controlled valve.

The RT’s main chassis change is the adoption of ESA II, an updated version of the Electronic Suspension Adjustment system. This allows adjustment of preload and even spring rate for the first time, to one of three positions intended for riding solo, two-up, or two-up with luggage. In each preload position, there is a choice of three damping settings: Comfort, Normal and Sport. (Only damping can be altered with the bike moving.) The differences between the damping settings are significantly greater than with the previous ESA system.

I seldom ride a motorcycle on a test track with the transmission resting in the fifth cog. While riding through numerous tight curves where speeds fall below 50km/h, I was still not using my left hand or the left toe for that matter to downshift. Neither did I shift my body weight while taking turns. Instead, I sat upright like a typical commuter trying to experience the traffic negotiating manoeuvers of Bajaj’s all-new traffic buster machine, the Pulsar 135LS. Even with my weight and a few slightly uphill sections, the bike pulled cleanly from low speeds in the highest gear. I have to admit, I was beginning to enjoy riding the LS in this manner on the track before being flagged down by my colleague Ravi who was waiting patiently for his turn to hit the track.

But why was my riding so different in the first place? Apart from its blistering engine (for the capacity) and eye-catching looks, the LS is also about its ability to weave in and out of traffic effortlessly at low to midrange engine speeds. As our test ride session was scheduled at Bajaj’s racetrack, there was no better way to understand their new product than ride it in the manner explained above.

In the recent few months, Bajaj’s dominance in the premium commuter segment has seen a huge positive growth. The Pulsar model line-up comprising of the 150, the 180 and the 220 models has strengthened its presence in the market. But Bajaj wanted to provide something for young enthusiasts that would combine the best of both worlds – a 125cc machine’s efficiency and sticker price with a typical 150cc bike’s performance and looks. Hence, the birth of the Pulsar 135LS.

At first glance, you might mistake it to be the Hero Honda Hunk, at least I did. But once you notice the side and the rear profile, all similarities end. The front seems to use a FZ style headlamp stacked between sharp plastic panels and a smart little visor on the top. The tank looks like a typical Pulsar one but has neat side plastic shrouds with the four valve sticker – more on that later. The step seats are a welcome addition and the rear panels again remind you of the bigger Pulsar models, though they end very sportily with a twin split grabrail and a striking tail lamp. I particularly loved the fender less treatment at the rear, although to comply with government regulations, Bajaj had to use a tyre hugger – the first mod chop most youngsters will do once they get the bike. Another unique design treatment is the tapering exhaust that might not be to everyone’s liking. At 1995mm, the LS’ wheelbase is even longer than its own elder sibling, the Pulsar 150.

This bike, for the first time in the Pulsar range history, makes use of the engine as a stressed member in the box section chassis. An all-new swingarm was engineered for the rear and the bike sports tubeless tyres which are fast becoming a norm on Indian motorcycles. Though the bike has a longish swingarm, the steep steering angle made sure it behaved well around the test track, being over eager and enthusiastic to lean into corners and scrape the pegs without upsetting the entire balance. Even while gunning down the last straight at triple digit speeds, the bike felt reassuringly stable in spite of early morning crosswinds. I really couldn’t judge the behaviour of the suspension for Indian conditions due to the limited testing environment, though our readers should get that report in the next issue.

Now isn’t that a familiar console? Yes, the Discover 135 has the same one	Smooth and punchy – the 135cc mill impressed us

Coming to one of the main aspects of the LS -its engine. On paper, it might feel average for this segment with a 134.6cc motor, but dig deeper into its technicalities and you are bound to be impressed. To start with, this is India’s first indigenously developed four valve powertrain which enhances the engine’s breathing characteristics. This combined with Bajaj’s patented DTS-i tech gadgetry helps in giving the bike not only a punchy low and midrange, but also class demolishing top end performance. 13.5PS of power might not be tyre shredding, however when you factor in the bike’s impressively low kerb weight of just 122 kilos (which in itself is lower than all the other 125cc bikes from the competitors and hence the tag LS or Light Sports), you are bound to be surprised once the performance test data is revealed. A 0-60km/h timing of 5.18 seconds not only makes the 135LS the quickest in its segment, but it also ends up shaming most 150cc bikes out there. However due to it’s relatively lower engine capacity, as speeds climb in excess of 80km/h, the bike starts losing steam, hitting the ton mark at a shade over 19 seconds. Nonetheless, it still remains quicker than some bigger bikes and further goes onto hit a genuine top whack of 112km/h with the over enthusiastic speedometer registering in excess of 120km/h!

As I mentioned in the opening lines, the LS also impresses in the way it gathers speeds at low revs. The 30-70km/h roll on, for example, takes just 7.31 seconds in the third and 9.51 seconds in the fourth. The engine has the ability to pick up speeds from as low as 25km/h, however, compression knock is very evident especially with a pillion while pulling from low engine speeds. The motor, however, remains smooth and vibration free until you rev it close to the red line. The light weight of the bike also endows it with impressive handling capabilities and an experienced rider won’t find it difficult to indulge in peg scraping antics when the environment allows. The brakes perform well too and stunt junkies will appreciate the bike for its ability to roll on the front one easily.

All said and done, no matter how good a bike is, a lot boils down to its sticker price in India. Most top of the line 125cc bikes in the country retail at around Rs 50,000 (ex-showroom). The Pulsar 135LS, with extra grunt and a bigger bike feel at almost the same price, translates into more bang for your buck. Not to forget that in spite of all that segment shattering performance, ridden sanely, the bike still manages 60km to a litre in the city and close to 80km on the highway. Icing on the cake? You bet!
