POWER DELIVERY, TORQUE AND ABSOLUTE CONTROL

BETA RR RACE 2T 300 2027

POWER DELIVERY, TORQUE AND ABSOLUTE CONTROL

The ultimate expression of power, traction and Betamotor’s two-stroke racing technology. With the introduction of the new engine head geometry, the recalibrated exhaust valve and the new main bearings, the 300cc model refines its power delivery at low and medium revs, confirming its status as the ultimate weapon on racetracks around the world.

The 300cc 2-stroke engine has taken a decisive leap forward in terms of performance. Beta’s engineers have revised the engine head geometry and exhaust valve timing with the aim of making the engine’s response even more progressive and controllable at low and medium revs, maximising the usability of the torque. Added to this are the new main bearings, which reduce internal friction, delivering a lively, full-bodied power delivery that responds instantly to the throttle control.
