MECHANICAL EFFICIENCY AND IMMEDIATE RESPONSE

The quintessential two-stroke ‘quarter-litre’, designed for riders who demand instant responsiveness, lightness and torque that’s always on tap during races. With the MY 27, the RR RACE 2T 250 takes a significant evolutionary leap forward thanks to the introduction of new main bearings, combined with KYB suspension settings developed directly on the world’s race circuits.

The 250cc 2-stroke engine features a key mechanical upgrade for the MY 27: the introduction of new crankshaft bearings. This solution drastically reduces internal engine friction, improving the smoothness of the crankshaft’s rotation and overall reliability. The benefit is an even more responsive, lively and powerful power delivery across the entire rev range, ensuring immediate traction and decisive acceleration when accelerating from a standstill or picking up speed from low revs.
