    Liquid-cooled 4-stroke single cylinder engine

    Featuring a free-revving short-stroke configuration, the liquid-cooled 125cc 4-stroke engine drives though a slick-shifting 6-speed gearbox to give ultra-responsive acceleration. Equipped with a highly efficient fuel injection system, the R125 delivers thrilling performance with outstanding fuel economy.

    Lightweight aluminium chassis components

    R-Series DNA is evident in the light and immensely strong aluminium swinging arm which ensures precision handling and confident roadholding. A redesigned rear linkage gives even greater riding comfort, and with the brake pedal, shift lever and passenger footrests all made from aluminium, the R125 has a leading specification.

    Multi function LCD instrumentation

    The R125 is equipped with one of the most sophisticated LCD instrument panels seen on a 125cc bike. Its comprehensive backlit display includes a digital speedometer with a bar type tachometer, and the advanced design also includes data on fuel level and fuel consumption, as well as distance and range trip meters.

    R-series inspired bodywork

    With its aggressive twin headlight fairing and central air intake, there's no mistaking the R-series heritage in the latest R125. The radical front cowl gives this class-leading 125cc supersport a genuine big-bike look and feel, and the slippery aerodynamic bodywork is ready to slice through the air for maximum riding excitement.

    High-rigidity upside down forks

    Just like the legendary R1 and WSS-winning R6, the R125 is equipped with upside down front forks which offer high levels of rigidity for precise and responsive handling characteristics. To emphasize the R-series racing heritage the front fender features a carbon-look finish, giving the R125 a real big-bike character.

    Lightweight race-bred wheels

    Lightweight wheels utilize a race-bred multi-spoke design featuring thin Y-shaped spokes that contribute to a low unsprung weight for responsive suspension action and precise handling. And with a 100/80-17 front tyre and wide section 130/70-17 rear tyre, this 125cc superport bike is built to slice though the bends.

    High specification brakes with ABS

    The R125’s advanced braking system is a spin off from our larger-capacity R-series models. Featuring a floating 297mm diameter disc, the high specification radially mounted caliper is designed to deliver strong and effective braking performance and outstanding initial response.
