    Traction control system

    The R125’s traction control system gives you a high degree of controllability during hard acceleration by reducing driving force to the rear wheel, if any tendency to slip is detected. The premium and high specification of the bike also includes an Assist & Slipper clutch for controlled deceleration. And the R125 is also pre-wired for the fitment of an optional quick shift system for seamless upshifts.

    Torque rich 125cc EURO5 4-stroke engine with VVA

    Producing 11 kW (15 HP) at 9.000 rpm, the R125’s torque rich 125cc EURO5 4-stroke engine benefits from large intake and exhaust valves and a compact combustion chamber for impressive acceleration. Its performance-boosting Variable Valve Actuation (VVA) system optimizes the valve timing, to secure good torque delivery and powerful response throughout the whole rpm range – and the sports exhaust system sounds great at all speeds!

    High specification suspension

    Like every Yamaha R-Series, the R125 is equipped with state-of-the-art suspension.

    Equipped with a large diameter 292mm floating front disc as well as a 220mm rear disc, the braking systems of the R125 produce outstanding performance.

    Wide 140-section Michelin Pilot Street rear tyre

    To confirm its strong R-series DNA the R125 runs on Michelin Pilot Street tyres, with a wide 140/70-17 rear tyre that gives excellent stability and confidence in cornering. Offering a good balance of grip and durability, this Supersport style tyre is designed to enable you to optimize the potential of the engine’s broad spread of power – and its wide section accentuates the bike’s aggressive R-Series attitude.

    Sporty riding position

    Besides the M1 style MotoGP®-inspired cockpit, the race-bred R125 is also equipped with a 2-piece rider and passenger seat featuring thick foam for a smooth ride.
