    New ECU mapping

    Featuring new ECU mapping for improved throttle feel and smoother pick up, the WR450F's torque-rich engine delivers strong, balanced and easy to control power that enables you to take control and discover your true riding potential. And for reduced weight the electric start 450cc liquid-cooled DOHC fuel-injected 4-valve engine has no kickstarter mechanism

    Reverse cylinder head with straight intake

    First seen on our MXGP-winning YZ450F motocrosser, the WR450F's revolutionary reverse cylinder head features a front facing intake and rear-exit snaking exhaust. By increasing intake and exhaust efficiency, this industry-leading layout optimizes the engine's linear torque feeling, giving deep reserves of highly controllable power.

    High levels of controllability

    The WR450F has been created using the same DNA as our World Championship winning YZ450F motocross model. For improved rideability and reduced fatigue this enduro bike runs with revised fuelling and ignition settings - while the wide ratio gearbox and enduro-specific suspension settings gives you full control.

    Wide-ratio 5-speed transmission

    The WR450F's transmission features gear ratios that enable you to fully optimize the bike's linear torque and deep reserves of controllable power. Featuring a light enduro clutch that's built to handle extreme conditions, the wide-ratio 5-speed transmission is ready to master all types of high and low speed off road terrain.

    Enduro radiator with cooling fan

    To handle the unique and extreme demands of enduro and rally riding, the WR450F is equipped with specially developed radiators that feature a different core pitch to the YZ-F, as well as newly designed shrouds. There's also a lightweight electric fan that cuts in to keep the engine running efficiently in adverse situations.

  • alt

    Lightweight, mass centralized design

    With its ground breaking reverse cylinder head and rearward slanting cylinder, the WR450F represents a new direction in enduro bike design. As well as boosting the engine's linear torque feeling, this compact and lightweight layout contributes significantly towards mass centralization for lighter and more agile handling performance.

    ISDE winning technology

    Using the knowledge gained from our 2017 ISDE winning WR450F as well as our World Championship winning YZ450F, Yamaha's designers have developed this WR450F using the most advanced engine and chassis technology ever seen in the enduro world. With its lightweight agility and strong, controllable power, this high-tech enduro bike changes everything.

    Main switch-free electric starter

    For quick and convenient starting this next generation enduro bike is equipped with a switch-free ignition system that enables the rider to fire the engine up with one push of the electric start button - and there's also an auto decompressor that cuts in and reduces the effort required to start the engine.

    Aluminium beam frame

    Developed alongside the latest reverse head engine, the aluminium bilateral beam frame is a spin-off from the 2017 ISDE winning WR450F and World Championship winning YZ450F. Running with an optimized rigidity balance, its compact and lightweight design offers agility with stability - allowing you to make full use of the deep reserves of linear torque.

    Optimized suspension settings

    Optimized suspension settings give outstanding performance over all types of extreme terrain. The highly acclaimed KYB® Air-Oil-Separate front forks ensure stable and predictable handling at low and high speeds. At the rear end, Yamaha's famous link-type Monocross suspension system delivers effective traction with a high degree of control.
