    2021 Yamaha WR250F Features​



    TOP FEATURES
    High-Tech Quarter-Liter Enduro Racer
    The WR250F[​IMG] builds on Yamaha’s exceptional motocross race platforms—the YZ250F[​IMG]—with added features and unique settings designed to optimize the WR® for enduro riding.
    Strong and Compact Electric Start Engine
    A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give WR250F riders a broad spread of useable thrust with excellent high-rpm power. All available with the convenient push of a button starting that features a compact starter motor system battery.
    Advanced Alloy Frame
    Yamaha’s bilateral beam aluminum frame is derived straight from the YZ250F to centralize mass and provide an ideal balance between cornering feel and straight-line confidence.
    Class-Leading Suspension
    Yamaha uses KYB® spring-type forks on the WR250F, with industry leading functionality and easy tuneability for a wide range of conditions.
    EPA-Compliant Emissions
    Thanks to carefully balanced ECU tuning and a Forestry Service-complaint spark arrestor-type muffler, the WR250F is ready to go where you want, when you want.
    ENGINE
    Rearward-Slanted Cylinder Design
    The WR250F’s distinct rearward-slanted cylinder design—complete with rear exhaust and forward-mounted intake system—features a cylinder head that works with the frame geometry for optimized weight distribution. Inside, the engine features all of the updates found in the race-focused YZ250F: a straight intake tract, aggressive cam profiles, high-compression “box bridge” piston design with DLC-coated piston pin, and more.
    Enduro Engine Tuning
    WR250F-specfic ignition and fuel injection maps are optimized for enduro riding and racing, for exceptionally smooth and controllable midrange power with longer-lasting pulling power in the top-end.
    Unique Intake and Exhaust Systems
    The WR250F features a two-piece air filter that works in conjunction with the tuned intake tract length and a WR-specific muffler to boost the linear feeling of traction and drive. Not only is the WR250F muffler completely mechanical—eliminating the need to repack—it integrates a U.S. Forestry Service-compliant spark arrestor, too.
    High-Capacity Radiator
    The WR250F uses a large radiator with excellent cooling capacity shared with the YZ250F motocrosser, complete with a cooling fan for consistent performance during the toughest enduro rides.
    Electric Starter System
    The WR250F features a compact electric starter system to simplify restarts on the trail and add convenience everywhere else, powered by an ultra-compact lithium battery.
    Advanced Fuel Injection
    The engine breathes through a 44mm Mikuni® throttle body fed by a high pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding elevations and conditions.
    Robust Transmission and Clutch
    The WR250F’s wide-ratio 6-speed transmission is shared with the YZ250FX, providing the optimized gear for tight technical terrain as well as wide open fire roads. The clutch system has a specific friction plate combination for heat dissipation and easy clutch lever effort.
    CHASSIS/SUSPENSION
    YZ250F-Derived Bilateral Beam Frame
    Yamaha’s refined aluminum frame provides high performance on technical, aggressive terrain sections as well as comfort for those long days in the saddle, with frame spars and engine mounts developed alongside the YZ250FX cross country racer to centralize mass for the best possible balance of bump absorption, stiffness and rider feeling.
    Compact Body and Seat Design
    The WR250F features stylish bodywork from tip to tail, including a large 2.15 gallon, mass-centralized fuel tank. The body design is narrow for more comfortable knee grip and control feeling while the seat gives the rider additional room to move aboard the machine. Even the rear fender is designed for added rigidity to make moving the machine easier.
    Class-Leading Suspension
    The WR250F’s industry-leading, fully adjustable KYB® coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption, with mid-speed valving tuned for improved feel at slower fork speeds.
    270mm Front Brake
    Large 270mm front disc brake coupled with aggressive pad material offers outstanding braking performance and machine control, with exceptional stopping power and controllability.
    Cross Country Wheels and Tires
    The WR250F features an 18-inch rear wheel to help prevent pinch flats and provide additional comfort across rough, broken terrain.
    ADDITIONAL FEATURES
    Enduro-Ready Detailing
    The WR250F includes a range of enduro-specific upgrades compared to the YZ250F motocrosser, including a wide, full-coverage composite engine guard, 18-inch rear wheel, large 2.15-gallon fuel tank, radiator fan, sealed O-ring chain, fuel level and engine warning lights, steel rear sprocket and a high-mounted folding aluminum kickstand.
    Multi-Function Enduro Meter
    The display’s Standard mode features the speedometer, two trips meters and clock functions, while Race mode features average speed, timer and trip functionality.
    Compact Headlight Unit
    The WR250F’s updated headlight fairing and compact taillight unit centralize mass and improve the racy, agile styling of the machine.
    Embedded Graphics
    Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
