The RR X-PRO 125 2T is the lightest and most easy to handle of the X-PRO family. Ideal for young riders coming up from the lower categories, but also for more experienced riders looking for an agile and fun bike.
Engine and gearbox: More responsive, explosive and fun
The new RR X-PRO 125 2T features a completely redesigned piston and cylinder head, with a new combustion chamber that increases torque, power and responsiveness. The result is an even more brilliant and powerful engine, capable of delivering explosive performance in all conditions.
To support the more aggressive power delivery, the 2026 model year also introduces a totally new gearbox, with reinforced gears and optimised ratios: faster, more precise and more reliable gear changes, to get the most out of every gear.
