    Switch-free electric starter

    For easy and reliable starting every time, this next generation enduro bike is equipped with a switch-free ignition system that enables you to fire the engine up with one push of the electric start button. And to reduce the WR250F's overall weight, the kickstart mechanism has been removed.

    Yamaha Power Tuner

    The Yamaha Power Tuner allows you to adjust the WR250F's performance character to suit different riding conditions. This plug-in accessory gives you a wide range of engine tuning options that enable you to select your own custom settings from the newly developed 3D mapping. With the Power Tuner you now have factory tuning technology at your fingertips!

    Smoother enduro clutch and wide-ratio 6-speed transmission

    The WR250F's transmission is equipped with a clutch that has been specially developed to handle hour after hour of punishment. The push lever gives even smoother clutch action - and to optimize the stronger performance of the upgraded engine, there's a purpose-built wide ratio 6-speed transmission.

    Optimized suspension settings

    The enduro-specific suspension runs with optimized settings for enhanced control. The KYB® 48mm upside down AOS front forks give speed-sensitive damping for class-leading performance on varied terrain. And at the rear end this high-tech 250cc 4-stroke runs with a link-type Monocross rear suspension system and KYB® shock for ultimate traction.

    Mass centralization

    The mass centralized design is a concept we pioneered, and it's what gives the WR250F the edge over the competition. By locating major components like the fuel tank, cylinder and exhaust system close to the centre of the chassis, we've been able to create an enduro bike whose agile handling gives the Yamaha rider a real advantage - all day long.

    Compact YZ250F-type aluminium chassis

    To optimize the performance gains of the upgraded engine, the WR250F comes with a lightweight YZ250F-based bilateral aluminum beam frame. Its compact design offers an idealized balance of strength and rigidity, giving you the confidence and ability to take full control over all types of extreme terrain, at low and high speeds.

    Reverse cylinder head

    The reverse cylinder head has shorter intake and exhaust ports for stronger top end power, while cams and valve springs enhance the low to mid range torque. And for a broad band of balanced performance, the WR250F gets a lightweight flat top piston and hardened DLC-coated low friction piston pin, as well as a crank and con rod.

    Revolutionary 250cc 4-stroke engine

    Equipped with 4 titanium valves, the revolutionary rear slanted liquid cooled 250cc fuel-injected DOHC 4-stroke engine gets a remapped ECU giving optimized power and an improved rev limiter. For balanced power output with boosted reliability, the bottom end features a revised crank balance ratio and a nickel-chomoly steel con rod.
