The perfect embodiment of the RideAbility philosophy applied to the largest displacement in two-stroke motocross engines. The RX 350 2T stands out clearly from traditional race-ready bikes, offering an incredibly smooth, linear and usable power delivery, ideal for riders seeking a relaxed yet effective riding experience based on long gear ratios and constant traction. With the updates introduced in MY27, this model increases its raw power and refines its structural strength, establishing itself as an absolute engineering benchmark within Betamotor’s cross line-up.
