Fast Fun
Motocross-bred power and confidence-inspiring handling from a lighter, slimmer new chassis combine to produce our fastest, most fun 250 enduro yet!
Features New for 2026
All-New Aluminum Bilateral Beam Frame
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.
Revised Suspension Settings
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.
New Air Intake
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.
New Four-Level Traction Control
New four-level Traction Control is enabled through Yamaha's groundbreaking next-generation Power Tuner App, along with additional convenient features including a lap timer, data logging and helpful setup guides.
