PERFORMANCE REFINED
The class benchmark. Yamaha took the championship winning YZ450F and made it even better with highly refined power and handling characteristics for a level of feel and control that unlocks a racer’s full potential.

Features May Include:

Powerful 450cc Four-Stroke Engine

• Featuring a reversed cylinder head layout, forged aluminum piston, 39 mm titanium valves, lightened crank assembly and dry sump lubrication, the 2026 YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.

Advanced Aluminum Bilateral Beam Frame

• The precisely tuned aluminum bilateral beam frame 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 lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.
