Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App allows owners to adjust air/fuel mixture and ignition timing to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more. Features include an intuitive “Simple Tuning” slide bar for quick engine mapping adjustments, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides. Best of all, it's free-of-charge.
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.

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.
