  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.

  New Hydraulic Clutch

CHASSIS

Aluminum Bilateral Beam Frame

A redesigned 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.

Compact Lightweight Hydraulic Clutch

The clutch design uses a disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother engagement and excellent feel. A new clutch cover employs a stylish geometric design that helps minimize scratching and lends a premium look.

Slim Body & optimized Ergonomics

Revised Suspension with Toolless Fork Adjustment

The YZ450F's front fork features a hand operated compression clicker for simple, toolless adjustments. To match the new chassis, front fork and rear shock damping characteristics are tuned to optimize traction and bump absorption.
