- Class-Leading Suspension
The Yamaha WR250F uses KYB® spring-type forks 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-compliant spark arrestor-type muffler, the WR250F is ready to go where you want, when you want.
- 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-specific 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 lead acid battery powered compact electric starter system to simplify restarts on the trail and add convenience everywhere else.
- 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.
- YZ250F-Derived Bilateral Beam Frame
Yamaha’s refined aluminum frame provides high performance on technical, aggressive terrain sections and 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 feel.
- 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, while the seat gives the rider additional room to move. 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.
- 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.
- 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.
- 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.
