One of the prime areas of focus in case of the 125M is mileage, emphasised by the ‘M’ suffix in its name. Bajaj have de-tuned the 124.6-cc engine of the T/ST to make it even more frugal in the 125M while still giving it enough horses, and it gets a four-speed gearbox with an all-up shift pattern. There aren’t any noticeable improvements in engine refinement in the 125M, but the throaty exhaust note may have a sporty appeal for some. The 125M produces 11.5 PS at 8,000 revolutions per minute, which is 1.5 PS less than the 125T/ST, but is produced at a lower engine speed, so the engine undergoes lesser stress. The 10.8 Nm of peak toque is identical, but is available at 6,000 RPM instead of at 7,000 RPM. The engine specifications aren’t really the highlight of this motorcycle, but since it weighs just 118 kg with all the fluids, it performs really well. The 125M accelerates to 60 km/h from standstill in six seconds and has a top speed of 98.5 km/h. The engine feels responsive throughout the rev range and the gear shifts are precise, so it has that essential edge when fighting for gaps in the traffic.
We weren’t able to verify the fuel efficiency of the 125M during the press event, but since the 125T/ST gave us 58.5 km/l in our standard test, the 125M’s claimed fuel efficiency figure of 60-65 km/l seems appropriate and it should offer a range of nearly 600 km on a full tank. As for the braking, the 125M has gained from Bajaj’s parts sharing strategy. The 125M has a 200-mm disc brake on the front wheel and a 130-mm drum brake on the rear one. Together, they provide more than enough retarding force and the bike feels stable under braking because the disc brake has a progressive feel and the bike has better tyres compared to the 100M.
