Yamaha took the championship winning YZ450F and made it even better—more powerful, lighter, slimmer, with enhanced overall stability and more agility than ever! Because the best don’t rest.
NEW FOR 2025
A revised rear suspension linkage and updated shock settings enhance stability and traction feel in a wide variety of riding situations. To match the rear linkage revision, front suspension settings have also been updated including incorporating delta-shaped piston shims providing calmer front-end behavior and improved rider comfort.
To match the new suspension components and settings, the front engine mounts have been revised improving chassis compliance and enhancing handling stability.
An updated clutch design increases the number of holes feeding oil to the clutch plates from 6 to 18, improving cooling efficiency for excellent reliability even under hard, continuous use.
