    Everything about the R125 is designed to give you the ultimate Supersport riding experience. Inspired by Yamaha’s MotoGP® bike, the racy cockpit features a new high-quality R1-type handlebar crown – and the clip-on handlebars are equipped with a new R1-replica right switch cluster.

    Dynamic next generation Yamaha Racing design

    Inspired by Yamaha’s winning race machines, the R125’s dynamic all-new next generation aerodynamic bodywork gives this lightweight Supersport a commanding big-bike look and feel. Its aggressive R-Series face features an M-shaped nose inspired by the M1 MotoGP® bike to underline its racing heritage – and the latest Icon Blue and Tech Black colours and graphics highlight the premium finish of the completely new body design.

    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 optimises 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. The 41mm KYB upside-down front forks provide an idealised balance of shock absorption and handling stability – while the rear link-type suspension system is designed to ensure excellent road holding together with a high level of riding comfort.

    Deltabox frame and aluminium swingarm

    Yamaha’s race developed Deltabox frame design is a signature element of R-Series Supersport technology, and its combination of low weight with high strength ensures agile and stable handling performance. And combined with premium front and rear suspension and short aluminium swingarm, this class-leading chassis provides you with a lightweight Supersport handling experience.

    Outstanding braking performance

    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. Featuring a 2-pots radial mount front caliper and lightweight front and rear discs for powerful and progressive stopping power, this sophisticated braking set-up gives you precise and accurate control.

    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 optimise the potential of the engine’s broad spread of power – and its wide section accentuates the bike’s aggressive R-Series attitude.

  • alt

    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. With an optimised handlebar position as well as a slim-sculpted fuel tank with recessed knee-grip areas and aluminium rear set footrests, the R125’s ergonomics give a balanced riding experience that's both sporty and comfortable.
