Engine
450cc Four-Stroke Engine
Yamaha Power Tuner App
Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App is revised to be even more user-friendly.
Traction Control & Updated Launch Control
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 updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
Hydraulic Clutch
Chassis
Aluminum Bilateral Beam Frame
An 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.
Slim Body & optimized Ergonomics
Suspension with Toolless Fork Adjustment
The YZ450F's front fork features a hand operated compression clicker for simple, toolless adjustments. To match the chassis, front fork and rear shock damping characteristics are tuned to optimize traction and bump absorption.
