The first session had been horrible, but this was fantastic fun. The rain was coming down quite hard now, and the slippery Misano track had already seen three crashes this morning. But as the RSV4 tipped smoothly into the turns, drove through with a guttural V4 growl, and then catapulted towards the next bend with a stirring howl, the speed and poise of Aprilia’s new challenger was thrilling despite the conditions.

This was the upmarket Factory version of the Italian firm’s new super-sports flagship, and the name was well deserved. The production RSV4 was managing — with its looks, its agility, its suspension control and sheer power — to give a flavour of the works V4 on which Max Biaggi has shaken up the established players in the first weeks of the World Superbike season.

It shouldn’t really have been a surprise to anyone that Aprilia would be so competitive so quickly on the track, or that the 183PS production RSV4 would be mighty good to ride. After all, the Noale firm is part of the Piaggio Group that is Europe’s biggest bike firm. More than three years and 25 million euros have been invested in this project, after starting with a blank sheet of paper.

“Our goal was clear,” Piaggio’s director of motorcycle engineering Romano Albesiano had said last night. “We wanted to build the fastest motorcycle on the racetrack, for use on track and road. There were no limitations; no constraints. We were free to choose the engine layout and the chassis. We wanted to make the most compact super-sports bike ever built, and we did it in a unique way: by combining the work of two teams, the engineers of the R&D department and the race department.”

Aprilia’s history also pointed to the RSV4 making an immediate impact. Back in 1998 the original RSV Mille V-twin, the firm’s first ever superbike, was a fine roadster although it never turned World Superbike race wins into a championship victory. This new bike’s links to the V-twin include its trio of headlights and aluminium beam frame layout. But this all-new V4 is very different; lower and more compact, as well as more stylish.

The dozen RSV4s poking from Misano pit garages had cut through the early morning gloom. Miguel Galluzzi, creator of Ducati’s Monster and now head of Piaggio’s design team, has given the V4 a unique and aggressive look. The sharp lines of the cut-down fairing and sculpted tailpiece are reflected in the upswept black silencer. The aluminium frame spars are smooth and polished. Classy, typical Factory-spec touches include Öhlins suspension, Brembo radial Monoblocs and forged Marchesini wheels.

There’s nothing particularly unusual about the view from the rider’s seat, which is quite low and slim (although luxurious compared to the razor-blade that a pillion gets to sit on). Clip-on bars bolt to 43mm forks whose gold-and-blue tops jut through the cast top yoke. A low screen gives a view of the digital display. But there was definitely something special about the way the motor came to life with a raw, raspy V4 sound through the four-into-one exhaust, revving urgently as I blipped the throttle.

Being tall I was glad to find that despite the bike’s compact dimensions it didn’t feel cramped. But I wasn’t glad about the weather. Aprilia had gambled by holding the launch in north-eastern Italy, and had been rewarded by rain. The standard Pirelli Diablo Supercorsa SP tyres had been replaced by softer still racing wets, but I still didn’t enjoy relearning the slippery circuit, especially after one guy had crashed on the opening lap.

Miguel Galluzzi, Director of Piaggio Group Style Centre “I joined Aprilia in September 2006 and in my first week we started talking about this bike. The engine was already on the test bench. To start such an important project with a clean sheet of paper was a once in a lifetime opportunity. “But this was also a very difficult project because the RSV4 is very small, which gives extra problems for a designer. Size was the priority: the bike is nimble, the form is the function. Next priority was to make it distinctive — to create the face and the tail. When you see it coming it’s an Aprilia; when it’s going away it’s an Aprilia. “It was a conscious decision to keep the bodywork to a minimum, to let people see the engine and the frame. We thought there would be a lot of heat coming to the rider but when we tested the bike we found the hot air goes away. We spent quite a lot of time in the wind tunnel, but not too much because you can get confused by it. “The hardest part was the exhaust. Designing something that looks good with the necessary volume is a big problem. We tried maybe 150 different solutions: with one silencer, two, high, low, all over the place. When we got the look we started working on the sound — getting that metallic note when the valve opens up… “This is a good time at Aprilia. Everyone here has the passion for motorcycling. We have a budget, and the right way of working. This engine will lead to other exciting bikes. It’s going to be a lot of fun.”

The bike was not to blame for that. To suit the conditions Aprilia’s technicians had suggested setting the three-way injection map to the S for Sports position, the middle of the three. This is easily done, using the starter button while the motor is running. The T for Track setting gives max power in all gears; S smooths delivery and cuts max output in the lower three ratios; and R for Road flattens the torque curve and limits output to 142PS at all times.

With the Sport setting selected the V4 was fabulously flexible and sweet-revving. The close-ratio box’s first gear is tall, so I was splashing round the tighter bends with the revs dropping below 5000rpm. Yet the Aprilia picked up sweetly as I cautiously opened the ride-by-wire throttle. The engine note was initially gravelly; a touch of vibration briefly came through the footrests… then the sound rose in pitch and the motor smoothed as the bike stormed down the straight, kicking harder at about 8000rpm and hurtling towards the next turn.

On the wet track I was happy to leave the engine in S mode for almost all my three sessions. A brief test of the Road setting was enough to suggest that its gentler delivery might be useful occasionally. There was certainly not enough grip to allow any advantage from the Track setting’s full power in the lower gears, so I left that for another day.

Even in the dry there would have been no room at Misano to get close to the Aprilia’s near-300km/h top speed, but the bike was into fifth in the generally sweet-shifting box, and still pulling hard (no time to glance down at the digital speedo) on the main straight. That’s despite it having to cut through the wind and rain with my unaerodynamic body increasing the bike’s tiny frontal area despite my efforts to hide behind the low screen. The RSV4 certainly felt seriously fast; just how fast it is remains to be seen.

Full analysis of its handling ability will also have to wait, because the track didn’t dry out. It’s ironic that the RSV4 has the most comprehensively adjustable chassis ever seen on a production streetbike — giving the option to change steering geometry, ride height, swing-arm pivot point and even engine position — but the weather meant that I didn’t adjust even its suspension.

Instead I was happy that the front and rear Öhlins units were reasonably soft and very well damped, and gave good feedback in conjunction with the super-soft Pirellis. Misano’s relatively recent change to run anti-clockwise has resulted in a couple of tricky, decreasing-radius right-hand turns that put emphasis on front-end grip. So it was just as well that the RSV4 steered with a light and neutral feel that made direction changes easy.

I hadn’t expected to enjoy splashing round in the wet, even so. But during my second session the bike felt so precise, controllable and sweet-handling that I was having a great time despite the rain. I was cornering faster, leaving my braking later — glad that the Brembo Monoblocs gave plenty of feel, as well as stopping power — and winding on the gas earlier and harder out of the turns.

Then I had a biggish rear-end slide exiting the same second-gear left-hander that had seen a Greek rider high-side in the previous session. Clearly even this most rider-friendly and poised of bikes could easily exceed its limits. By mid-afternoon seven riders had crashed. Our final session was cancelled amid fears that Aprilia would run out of bikes for the following day.

So the RSVR Factory’s debut ended inconclusively, and the V4 still has work to do to show that it can be as competitive a production bike as its works-racer variant has shown it can be in World Superbikes. Perhaps Aprilia will give the Factory traction control, to compete with Ducati’s similarly priced 1198S, after introducing the cheaper RSV4-R model (with Showa springs, cast wheels and probably a simpler, non-adjustable frame) that is expected in about six months’ time.

Despite the weather and the crashes, though, the Factory had done enough to suggest that Aprilia’s second major assault on the open-class superbike market will be even more successful than the first. The competition is hotter than ever this year. But the RSV4 was mighty good in the rain, and will surely be better still in the dry. The superbike world has a very serious new challenger.

RSV4 Tech
This bike represents the start of an important new family for Aprilia, who threw huge resources into developing an engine that will eventually power naked and sports-touring models, as well as a base-model R version of the RSV4. The firm’s aim to create the “missing link between track and road” led them to use engineers from both R&D and race teams, and to run sophisticated computer programmes to analyse potential lap times of numerous engine layouts — including V-twin, triple and transverse four — before opting for a dohc V4.

An eight-valve V4 with cylinders at 65 degrees was eventually chosen as the best compromise between engine power — for which a larger angle allows more space for intakes — size and vibration level. “We chose the configuration with optimum performance and mass distribution,” said Piaggio’s bike engineering chief Romano Albesiano. “We wanted to keep the same weight distribution as the RSV V-twin, but make it smaller. The V4 is narrower and produces less vibration than an in-line four, so the higher development and manufacturing costs were worthwhile.”

The 999cc engine’s dimensions of 78 x 52.3mm match those of Yamaha’s latest R1, the most oversquare of Japan’s inline fours. Camshaft drive is by lateral chain to the intake cam, then gear to the exhaust cam, allowing very compact cylinder heads. Titanium is used for the valves; magnesium for the engine covers. A single balancer shaft minimises vibration. The transmission incorporates a six-speed cassette gearbox and wet, mechanical slipper clutch.

Breathing is highly sophisticated, featuring variable length intake ducts and ride-by-wire throttle control. The Weber-Marelli injection system incorporates two injectors per cylinder: one located downstream of the throttle valve for optimum low-rev response; the other in the airbox to boost fuel atomisation for maximum high-rev power. Peak output is a claimed 183PS at 12,500rpm. Pressing the starter button toggles between the maximum output T (Track) mode; S (Sport) which smooths output and limits torque in the first three gears; and R (Road) which gives a 142PS limit in all gears.

Aprilia’s road and race heritage demanded a polished, twin-spar aluminium frame. The RSV4’s is welded from cast and pressed sections, weighs 10.1kg, and is fine-tuned for optimum stiffness, giving 39 per cent more torsional rigidity than the RSV V-twin’s equivalent, but less rigidity elsewhere. The matching aluminium swing-arm weighs 5.1kg and is stiffer than its predecessor in every respect. Most of the 17 litres of fuel lives under the seat, for improved weight distribution.

The RSV4’s key chassis feature is a level of adjustability unprecedented in a production bike. Removable steering head inserts can alter the headstock position and alter rake and trail from the standard settings of 24.5 degrees and 105mm. Rear end height can be adjusted via the swing-arm pivot as well as shock length. Even the engine has alternative mounting points.

This adjustability is largely for the benefit of Aprilia’s Superbike race team, and springs from the race department’s close collaboration in the RSV4’s design. “Some targets such as power, weight and handling were clear to both the R&D department and the racing engineers, but the potential for chassis adjustment was a demand of the racing department,” says veteran RSV engineer Mariano Fioravanzo. “The adjustable frame was more complicated and expensive, and we discussed it a lot. But in the end the racing department got what they wanted.”

The Factory model’s cycle parts match the frame’s quality. The 43mm usd forks, piggy-back shock and steering damper are all by Öhlins. Forged wheels are a kilogramme lighter than those of the Factory V-twin, let alone cast alternatives. Brembo’s radial Monobloc calipers bite purpose-designed 320mm discs. Carbon-fibre mudguards and sidepanels contribute to a claimed weight of 179kg without oil or battery.

 

Phenomenally fast, better looking, easier to ride – but that’s simply not enough…

By Michael Neeves

Suzuki’s new GSX-R1000 K9 is a big improvement over the old K7/K8 model, but it’s not the giant leap forward we expected. It’s much more a case of evolution than revolution for the new Gixer, despite it having its most radical overhaul since it was introduced in 2001.

As well as looking similar to the old K7/K8, retaining the two-exhaust design, it’s pretty close in character too. It has the same ‘sit-in’ riding position and the same torrent of power when you twist the throttle. After a day riding it around the twisty Almeria circuit in southern Spain it’s clear it has new- found agility and friendliness the old bike lacked.

Compared to some of its competition, the GSX-R is not as razor-sharp in and out of the corners and it’s still missing that intoxicating mix of grunt and light weight that made the old K5/K6 the sensation it was at the time. With things like extra soundproofing and the ever-bigger catalysts Suzuki have to run nowadays to get through Euro 3 laws, it seems the glory days of the waif-like K5 are gone forever.

Another sign that it’s now 2009 and not 2005, is the price. The new bike is the most expensive GSX-R1000 ever, costing £9800 (Rs. 7 lakh approx) when it hits showrooms at the end of March. Gixxers have always been at the most affordable end of the 1000cc market, but it’s now nearly the dearest, just after the new R1.

Thankfully the new GSX-R1000 motor isn’t as angry as before, thanks to a mass overhaul (see following pages) to smooth out the rough edges. Although power and torque remain the same, a claimed 185bhp isn’t to be sniffed at. It’s still an obscene amount, but it’s easier to use than before.

Power is smoother all the way through the rev range and there’s grunt oozing from every engine bolt, despite having a shorter stroke engine than before. All this gives you the confidence to twist the throttle further. But don’t worry, the GSX-R1000 hasn’t gone all soft. The K9 still retains that spine-tingling, evil bark when you blip the throttle and it wants to wheelie at every opportunity coming out of corners. The K9 isn’t as flabby as the old K7, either. That went a bit ‘90s GSX-R1100’, compared to the lightweight K5 model that went before. With its 5kg reduction in overall weight combined with the smoother power delivery, the K9 is now much easier to muscle around a track.

Last year we did our 1000s group test here at Almeria. The K8 GSX-R1000 finished up
two seconds behind the slightly more powerful ZX-10R and the significantly less powerful FireBlade, the overall winner of our test. It was only a fraction behind the R1, though. The Suzuki’s bulk and lack of agility (you could even feel the weight getting it off the sidestand) compared to the competition was the main reason it lagged behind. This is a technically demanding track dominated by constant throttle, high radius corners and flip-flop chicanes, so you need a bike which is light on its feet. What I do remember is that it flew down the long sixth-gear back straight like a guided missile, as it would with a true 169bhp at the rear wheel.

---

I’m sure the K9 would make a dent in those two seconds if we were to run the test again. It still has the power and speed and it’s even easier to get that throttle open now, but it still lacks the agility of the Blade and ZX-10R. And of course now it has the grunty new R1 to think about, too.

Except for the straight, the whole of Almeria can be taken in second gear, so you have to ride the big Suzuki like some hyper-speed twist-and-go moped for most of the lap.

For corner after corner, you dive in towards the apex and the K9’s slipper clutch eliminates most of the engine braking, so you get a nice smooth, balanced corner entry as you dial in more and more lean.

Getting settled into a turn, which seems to last forever, at full lean and holding a steady throttle is easy, thanks to the fuel injection’s smooth and predictable response.

As the corner opens up, gently feed on the power, stand the bike up, feel for grip through the rear tyre and squirt it. With the taps open the K9 rockets to the next corner, front wheel skimming the tarmac and bum forced back into the seat hump, leaving you hanging on by your fingernails. This is every inch a mad, bad, howling GSX-R1000, make no mistake.

Despite its shorter stroke engine, it’s still packed with enough grunt to let you take corners a gear taller than you need, and it’ll still fly out the other side pretty sharpish.

The only thing that stops us from really uncorking the full fury of the K9 at Almeria is the standard road-going Bridgestone BT-016 rubber. The engine wants to play, but it’s a lot to ask of an all-purpose sports tyre to be ragged senseless all day, with only a break for lunch. They do a great job of hanging on, they warm up fast, grip well and are predictable, but you really have to be careful with your right wrist with all that oomph to play with.

On stickier Michelin Power One rubber I rode the K9 on the following day at Cartagena, it turns sharper and you can explore more of the chassis and engine. The two big things to happen to the chassis are the new longer swingarm and the Showa Big Piston forks (see following pages), which replace the old
Kayaba units. Let’s start with the Blade-esque short engine/long swingarm combo.

Asked for by Suzuki’s racers around the world the new longer ‘banana’ style swingarm improves rear tyre grip and predictability. Given the power on tap and the relative low grip of the road tyres in track conditions, you’ve got to say the idea has worked, because it’s only when the rear tyre gets very worn that it starts to slide. When it does it’s with warning and gradual.

I say slide, move a bit is probably more accurate, compared to what Sylvan Guintoli was doing when he was out on track with us. Suzuki’s new BSB signing and ex-MotoGP god was laying the most obscene, thick black lines around the track, and in places you’d never think you’d be on the throttle, let alone at full powersliding fury! He’s going to be a star this year.

Just like the FireBlade, which runs a similar long swingarm, you have to watch it when pulling a wheelie, something that’s de rigueur for GSX-R1000 owners. The front wheel comes up gradually as normal, then when it’s at about chest height it suddenly goes ‘whoosh’, and tries to loop. If you’re ready for it fine, if you’re not you might wake up with a crowd around you.

So, job done there with the swingarm, then but the new forks take more getting used to. They offer a lot of resistance when you ease off or brake, and they only really seem to work at their best when you’re really pushing hard.

For the first few riding sessions at Almeria I didn’t like them, they felt too stiff and made the bike feel heavy and slow steering. They also made my wrists sore by the end of the day. But after a while you realise that the harder you push the better they feel and the more you can judge what the front tyre is doing.

First impressions of the K9’s handling weren’t good when I first climbed on, it felt clumsy, slow-steering and slightly unstable on the rear going into corners. A lot of this was down to set-up.

Once I’d got up to speed and used to pushing the front end harder to make the forks work and give me feel, it was better. I also added some more preload (on John Reynold’s advice) to the rear shock to speed up the steering. By the end of the day I finally started to have some serious fun. On sticky tyres the K9 is even better.

Brakes are an improvement but they still have the same GSX-R trait of feeling a bit mushy at the lever and liable to fade on hard use.

There’s no denying the K9 is a superb motorcycle. Suzuki have been fanatical about weight saving and balance and all these tweaks to make it lighter and grippier will no doubt pay dividends for the race teams who use the road bike as the basis of their Superbike or Superstock racers. Die hard GSX-R fans will still go all gooey over its evil exhaust note, searing top-end rush and slider-shredding cornering ability.

But there’s something missing and I can’t put my finger on it. I wasn’t left giggling, or open-mouthed after each riding session, like I should have been. It’s exciting, there’s no doubt about that, it’s still a wild 180mph superbike, after all.

But maybe with all the changes I was expecting a lightweight, snarling GSX-R1000 K5 MkII? Maybe it feels and looks too much like the old K7/K8 despite all its changes? Maybe it’s still too bulky? Maybe it’s just that Honda and Yamaha have moved the game on so much with the Fireblade and R1.

This is the best-ever time to buy a superbike. They might be edging towards £10k (Rs. 7-lakh approx), but they’re at such a high level, have so much power and are so packed full of technology it’s insane. The trick nowadays isn’t to find more power, it’s to harness the incredible bhp on offer.

The Suzuki ticks all these boxes, it’s better than the old K7/K8. But for me, it’s not different enough to really get me salivating.

Expert views

John Reynolds, Ex-BSB champ and Suzuki test rider “It’s a totally different chassis on the K9 from the K7. We’ve got a setting now where the bike works really well on the race track, and with a couple of turns of preload off the rear shock and a bit off the front end you’ve got a bike that’s wonderful for the road as well. “Suzuki have taken all the feedback from the riders in WSB and all the people who’ve been riding the K7 and K8 and worked out what’s needed is more grip on the back end. The way the geometry of the chassis is now, it’s really focused towards racing bikes more than anything else.”	Sylvain Guintoli, Crescent Suzuki BSB Team racer “It was an interesting experience riding the K9 today because I’ve never tried a road bike before. I was really surprised. I always thought road bikes on the track would be heavy and soft, but the K9 is good fun and fast. “We tried the K9 in Calafat a few weeks ago, but it didn’t have all the evolution parts on at that point. “Now we will ride the K9 full-spec superbike in a test this week, so we can find out exactly what it’s like. “ I’m looking forward to BSB, because we’ve done this test in Calafat and its gone really well and the team are really nice guys to be around and really good fun.”	David Taylor, Suzuki GB Sales and Marketing Director “With the K9, we’re trying to maintain Suzuki’s position of producing the top-selling bike over 125cc. “The racing side of Suzuki has brought the bike to a pinnacle with the front fork design and mass that’s been taken out of the bike. “We’re critically interested in how this year turns out with all the new stuff that’s going on in WSB and BSB, and all the Japanese manufacturers face an interesting challenge this year. I think we’ve timed it right with what we’ve got.”

Under the skin of the GSX-R1000

1. Engine
More compact and lighter than before, this is Suzuki’s first major-league engine redesign in the GSX-R1000’s history. The K9 has a shorter engine, by 59mm front-to-back, which lets the bike run a 33mm longer swingarm to help rear tyre grip. The overall length of the GSX-R1000 is still 2045mm.

The new motor has a bigger bore and a shorter stroke to give more power at high rpm, but it still has the longest stroke of all the Japanese 1000s. A long stroke equals grunt. This more ‘over-square’ engine layout will give race teams more scope for tuning and raising revs safely. The redline is set at 13,750rpm.

There’s more power up top, but Suzuki claims more low and midrange torque, too, thanks to new camshafts, a reshaped combustion chamber and a hike in compression ratio from 12.5:1 to 12.8:1.

A new two-piece crankcase design and a lightweight crank accounts for most of the engine’s 670g weight loss. The crank has a more efficient lubrication system. Titanium inlet valves are up from 30mm to 31mm and exhaust valves up from 24 to 25mm. Double valve springs replace single ones for better control at high revs. By stacking the primary and secondary gears and moving the clutch and crankshaft forward Suzuki has been able to make the engine shorter. The rear sprocket is down one tooth from 43 to 42.

The throttle bodies are now 10mm shorter, with 12-hole fuel injectors providing a finer spray for improved combustion. Inlet trumpets are now different heights to improve midrange and high rpm efficiency.

There’s still a slipper clutch, but it’s now cable instead of hydraulically operated.

The swoopy exhausts have titanium headers and servo-controlled butterfly valves to maximize power through the rev range. The system is 400g lighter than before.

2. Chassis
The new K9 weighs 5kg less than the old bike. The twin-spar aluminium frame is now shorter (from 645.8mm to 615mm) and comes in five welded-together sections. There’s also a cool ‘banana’ swingarm in cast aluminium, which lets the exhausts tuck in closer to the bike and is 500g lighter than before. The wheelbase is 1405mm – 10mm shorter than the K7/K8. Footrests are three-way adjustable, as is the gearlever. The new, removable cast aluminium subframe is lighter, too.

3. Suspension
Showa replaces Kayaba for the new K9. New 43mm Showa Big Piston Forks (BPF) are now fitted to the GSX-R1000 for the first time. They have just one 39.6mm internal piston per fork leg controlling rebound and compression damping instead of two. They run a lower pressure than conventional forks, so there’s less change of oil cavitation. Springs are at the bottom of the forks and are submerged in oil. This simpler set-up is 720g lighter than conventional forks. Both compression and rebound damping screw adjusters are on the top of each fork leg and preload is at the bottom.

The new Kayaba rear shock (500g lighter) is fully adjustable, including high and low speed compression damping, and works through a new suspension linkage (200g lighter). The speed-sensitive steering damper is 45g lighter.

4. Brakes and wheels
New forged aluminium Tokico one-piece radial calipers are more rigid and 250g each lighter than the old two-speed items. These are bolted to new-style carriers. Different sized pistons are used on the leading and trailing ends of the calipers for even pad wear. The radial-pump master cylinder diameter is down from 19 to 17mm for better feel through the lever. Cast aluminium wheels are 420g lighter.

5. Bodywork
The new fairing has a narrower lower section for better aerodynamics and a wider top to improve wind protection. SRAD (Suzuki Ram-Air Direct) intakes, which cut into the new headlight, have new internal louvres and are moved closer to the centre of the bike to take advantage of the higher air pressure there. A new slimline tail section has clear lens indicators and comes with a clip-in single seat unit. The new fuel tank retains its capacity of 17.5 litres.

6. Instruments
New clocks feature a gear position and power mode indicator, a bar graph showing how bright the clocks are and a lap timer, triggered by a button on the right bar.

On the road Michael Neeves rode the K9 from the launch in Almeria to Cartagena, the venue for our upcoming 1000s group test. The route took in twisty mountain roads and motorway. “If you’re coming from a K7/K8 GSX-R1000, the riding position will be immediately familiar. The seat is comfortable, you sit low and the bars are relatively high, so it’s OK to do distance on. “There’s still good grunt at low revs, though you can’t be completely lazy. Purr along in high gear at normal speeds and you need to stir the gearbox to overtake cars. “The Big Piston Forks still feel stiff through the twisties, but on normal roads they suck up the bumps beautifully giving very good ride quality. “The K9 is more fun on the road than on track. You can clutch up big power wheelies at a ton. There’s an excess of power to play with, making the K9 the dog’s on the road!”

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.
