Yamaha has just launched the new YZF-R15 earlier today. And if your hopes were pinned on a 250cc motor in the new bike, you're in for much disappointment.
The new R15 is powered by the same 150cc liquid-cooled, fuel-injected motor that did sterling service in its sporty predecessor. But don't let that cause you to burn that bank cheque made out to Yamaha yet, because the R15 version 2.0 does really have a few updates, rather than a mere sticker job.
Although the specs are largely the same, the new R15 boasts of a new Engine Control Unit (ECU), upgrades to the drive train (there aren't any details yet of what exactly has been done) and a new exhaust system. Work has also been done on the clutch, with a more robust axle shaft making it into the new R15 and the throttle body pulley has been grafted into a circular profile for better throttle response
