250 RR Enduro 2T

This is Beta’s little baby, perfect for those looking for a 2-stroke bike with a gentler character and with slightly lower power and torque ratings to ensure excellent handling. No doubt, this bike will be a protagonist in this season’s E2 category of the Enduro World Championship.

New cylinder: improves performance in terms of torque and power output throughout the rev range while keeping the response perfectly linear.

New combustion chamber: thanks to a slight increase in compression ratio, an upgrade in performance was possible.
