LIGHTER, SLIMMER, SHARPER, FASTER

The Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The Launch Control System continues to implement traction control and features an rpm limiting setting, which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm. Both systems are controlled through the Yamaha Power Tuner App.
The YZ450F's high-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork is recognized as the gold standard in the 450 class, providing exceptional feel and bump absorption. Front fork piston now incorporates delta-shaped slow speed shims for improved fluid flow, providing calmer front-end behavior and improved comfort. Matching changes to the front, the KYB® shock features revised settings and an updated rear suspension linkage for enhanced stability and traction feel in a wide variety of riding situations
Featuring a reversed cylinder head layout, forged aluminum piston, 39 mm titanium valves, lightened crank assembly and dry sump lubrication, the 2025 YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.
