2025 Yamaha WR250F

Motocross-bred power and confidence-inspiring handling from a lighter, slimmer new chassis combine to produce our fastest, most fun 250 enduro yet!

NEW FOR 2025

A completely redesigned aluminum bilateral beam frame based on the class-dominating YZ250F provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lightweight feel and increased front wheel traction, allowing the rider to enter corners with greater confidence and more line choices.

Yamaha's class-leading suspension has been revised for 2025 to lower the center of gravity for a more planted feel and increased ability in tight turns. Fully adjustable KYB® coil spring-type fork with speed-sensitive damping delivers exceptional balance between handling and bump absorption for championship-winning performance, and now includes a hand-adjustable knob for easy compression adjustments. Linkage-type rear suspension features a KYB® shock with revised settings to provide less pitch on corner entry/exit for improved stability.

Optimized intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact body. This redesign allows radiator shrouds to be two inches slimmer and the airbox cover to be lower and more narrow. The more efficient intake path also boosts mid- to high-rpm engine performance.

TOP FEATURES

Based on the class-leading YZ250F featuring Yamaha’s revolutionary front-intake, rear-exhaust, liquid-cooled, four-stroke power plant with an added sixth gear, wide-ratio transmission and a range of enduro-specific upgrades, the WR250F is super fast and fun.

The compact, powerful WR250F engine includes all the same race-developed technologies of the race-winning YZ250F, tuned for cross country performance. Revised airflow system, new cam chain and shorter muffler combine to increase linear power across the entire rev range.

The highly developed aluminum bilateral beam frame features precisely tuned flex characteristics for competition-ready performance. The forged section at the swingarm pivot, and improved engine mounting brackets provide a nimble lightweight feeling in tight, technical terrain while still providing control in fast sections. Yamaha's class-leading KYB® suspension has been revised to lower the center of gravity for a planted feel and increased ability in tight turns.

ENGINE

The revolutionary front-intake/rear-exhaust, liquid-cooled, fuel-injected, four-stroke engine has been developed for enduro competition. A new air induction system works with a high compression piston for a wide and linear spread of power.

Reversing the cylinder head while placing the intake forward and the exhaust to the rear allow for a straight shot, downdraft intake and straight exhaust port for maximized engine performance.
