2021 Yamaha WR250FSINGLE MINDED
The off-road enhanced trail bike of choice, rooted in legendary YZ250F performance, reliability and design.
Features may include:
- High-Tech Quarter-Liter Enduro Racer
The WR250F™ builds on Yamaha’s exceptional motocross race platforms—the YZ250F™—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.
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.
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.
ADDITIONAL
- 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.
