RR RACE 4T 390 2026

It’s RACE time!

RR Race bikes represent the race versions of Beta’s Enduro models, characterized by a series of modifications to the engine, suspension, frame and equipment, making the bikes ideal for giving their best on the track – always in the sign of RideAbility.

4-stroke engines received new maps with respect to the previous Model Year, to improve their delivery along the entire range. Whatever the displacement, Beta engineers optimized their linearity and usability of the propellers, to better manage the power available, at any speed, even on complex terrains.
