Features

Chassis / Suspension

  • ROBUST ALUMINUM FRAME: An all-aluminum bilateral beam frame similar to the YZ250F provides strength, lightness and durability for all riding conditions.
  • LIGHTWEIGHT SUBFRAME: Removable aluminum rear subframe constructed of square-section tube for reduced weight.
  • ADVANCED SUSPENSION: Industry favorite fully adjustable KYB® spring-type forks with speed sensitive damping with Kashima Coat™ and a KYB® rear shock, also with Kashima Coat™ and featuring a large 50mm piston. Both the forks and rear shock are tuned specifically for Enduro riding.
  • PURPOSE-BUILT TIRES: Special Enduro spec tires are used to maximize traction while delivering excellent wear.

Engine

  • UNIQUE ENGINE TUNING: The revolutionary, rearward slanted, high-performance liquid-cooled 4- stroke, 4-valve, fuel-injected engine has been tuned for enduro riding.
  • FUEL INJECTION: The fuel injection system uses 3-D mapped electronic control for the injection of fuel and ignition timing that are optimized for the challenges of enduro riding.
  • 6-SPEED GARBOX: A 6-speed wide-ratio transmission is used to improve traction in all types of conditions.
  • ELECTRIC START: Push button electric start makes starting the WR250F easy and convenient.
  • RACE-READY COOLING: YZ-based radiators feature an electric fan, ensuring stable cooling performance in tight and slow riding conditions.

NEW IN 2018

  • ENGINE: The cylinder head, piston, camshafts, transmission internals, ECU settings and a range of other internal updates, the 2018 WR250F features improved power delivery and enhanced durability derived straight from Yamaha's racing team development.
  • FRAME: The 2018 WR250F features the same advanced frame as the YZ250F motocrosser, including new engine mounts, to revise the rigidity balance and improve rider feedback.
  • RACING-DERIVED UPDATES: In 2018, the WR250F received a range of updates developed from the YZ250F and FX racing models, including new tires and revised suspension tuning, featuring a new fork seal wiper for durable sealing in the toughest conditions.

Other Features

  • FULL-FEATURED INSTRUMENTATION: An onboard Enduro computer is standard and features speedo, odometer, average speed, clock and more.
  • PRACTICAL TOUCHES: The WR250F features a headlight, taillight and skid plate. A side stand is standard for added rider convenience

Top Features

  • COMPETITION READY: Revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with 4 titanium valves based on the YZ250F™, with an added sixth gear and wide ratio transmission, among other modifications, make it perfect for Enduro competition.
  • NIMBLE CHASSIS: Nearly the same bilateral beam frame that is found on the championship winning YZ250F is used on the WR250F™. It places the engine and fuel tank close to the center mass of the bike for extremely light and nimble handling character.
  • FUEL INJECTION: A Keihin® 44mm throttle body fuel injection system is tuned for Enduro riding ensures smooth throttle response and easy starting in nearly all conditions. Plus the electric start button reduces rider fatigue.
  • ADVANCED SUSPENSION: Industry leading fully-adjustable KYB® spring-type forks with speed sensitive damping and a KYB® rear shock, each tuned with Enduro-specific settings.
  • ENDURO-SPECIFIC FEATURES: With a 2 gallon fuel tank, multi-function Enduro computer, 18-inch rear wheel, O-ring chain, skid plate and Enduro spec tires, the WR250F is ready to win right out of the box.
