• 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.

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.
