Engine Upgrades Beta continues to push the limits of its smaller displacement models. For MY26, the RR X-PRO 125 2-Stroke features a new piston and redesigned cylinder head with an updated combustion chamber. These modifications significantly increase both torque and peak power, giving the 125cc single-cylinder engine a more responsive and aggressive feel. The result is a lively, high-revving engine that delivers stronger midrange punch and improved overall performance.
Gearbox Refinements To handle the engine’s added power and ensure quick, precise gear changes, the gearbox has been upgraded with reinforced gears. Built for strength and calibrated for performance, the new transmission setup ensures that the 125cc engine delivers its best at every speed. (This gearbox update also extends to the RR X-PRO 200 2-Stroke.)
Frame Returning from the MY25 X-PRO models, the reinforced frame featuring a larger main spar section (vs MY2024) makes a comeback in the MY26 lineup. This design maintains balanced weight distribution while improving overall stability. The increased rigidity delivers just the right amount of flex, offering precise cornering performance whether navigating tight single tracks or tackling demanding Hard Enduro terrain.
Suspension First introduced in the MY2025 RR X-PRO models, the revised ZF suspension system continues to deliver an ideal blend of control and comfort. With a seat height of 930 mm (20 mm lower than the RR Race models) riders enjoy a more planted and confidence-inspiring ride, no matter the conditions.
SHC Fork (Single Hydraulic Chamber) The SHC fork was developed to optimise hydraulic efficiency and reduce weight—shaving approximately 250g. The fork’s dual-leg system separates the forks function: the right leg handles spring action, while the left leg controls hydraulic damping. Both stanchions have been refined, with a completely redesigned spring guide to enhance oil flow, reduce high-speed pressure spikes, and improve internal lubrication. The result is a more linear, predictable fork response that adapts quickly and smoothly to varied terrain, providing a notably freer and moreresponsive ride than traditional systems.
Swingarm For MY26, the rear axle diameter has been increased by 2 mm, now measuring 22 mm. This upgrade enhances stiffness and torsional resistance, significantly improving rear-endperformance during aggressive riding and high-load situations.
