New 2021 Yamaha WR250F Dirt Bike Motorcycle

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.
