Hero Xtreme 125R engine changes
The engine started life as the unit from the Glamour 125. Hero then tried to squeeze out some more power, but this came with increased vibrations and harshness. To offer the typically smooth experience that Hero customers expect, the engine was then given a balancer shaft as well as a silent cam chain.

The motor produces 11.55hp, which is not the highest in the class, but on par with the Raider, although its 10.5Nm of torque is a little lower than the TVS. But Hero was never promising segment-leading power; instead, its claims are that this bike has the smoothest engine in the segment and is also the most efficient, with a certified efficiency of 66kpl.
Hero Xtreme 125R refinement, performance

We only got to ride the bike for a few laps around Hero’s test track so it won’t be possible to comment on the fuel efficiency just yet, but the engine is definitely quite smooth. At low revs, it has that typical Hero refinement and there are only minor high-frequency vibrations to be felt at high rpms.

Performance feels quite good too, with good flexibility, a decent midrange and it can cross 80kph with ease. The five speed gearbox felt about average – not terrible, but not particularly slick and precise either. One area where the engine does lack compared to the TVS is in the sound – despite the stylish exhaust pipe, it’s pretty normal and doesn’t have that same bassy beat.
Hero Xtreme 125R handling, chassis dynamics

The new 125R isn’t just an Xtreme by name and it actually takes quite a few things from its bigger brother – the Xtreme 160. That includes the same 37mm telescopic fork (with retuned internals) and even the chassis is based on the unit from the 160.

As a result, this bike handles quite well, and while it had a soft and plush feeling, it was also good fun around Hero’s track. Like the Raider, this bike promises to be agile and entertaining but also easy to ride in the city. The main difference is that at 136 kilos, this is 13kg heavier than the Raider which is not insignificant, but it is still 8 kilos lighter than the Pulsar NS125.
Hero Xtreme 125R features, ABS

Braking is handled is 276mm front disc and a 130mm rear drum. There is no option for a rear disc, and actual braking performance is on par with what you would expect from this segment. However, Hero is pushing the bar by offering single channel ABS which is a first for the segment and it comes at a very fair asking price.

In fact, even beyond the ABS, the bike is quite well equipped, with full LED lighting, including a projector LED headlamp. It also has the same negative LCD dash that you will find on the Xtreme 160R.
