High Performance 450cc Four-Stroke Engine

The YZ450FX's thrilling new liquid-cooled DOHC four-stroke engine is designed to provide broad power character and ease-of-use, with ECU settings tailored to enhance both low-end tractability and top-end power.

Industry-Leading Yamaha Power Tuner App

Like having factory team support in your pocket, Yamaha's Power Tuner App is even more user-friendly with an intuitive “Simple Tuning” slide bar for quick engine mapping selections, new four-level Traction Control, a lap timer, and helpful engine and suspension tuning guides. Best of all, it's free-of-charge.

Advanced Aluminum Bilateral Beam Frame

The newly updated advanced aluminum bilateral beam frame with YZ450FX-specific engine mounts provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to tackle tight, technical courses with greater confidence.

Class-Leading Suspension

World renowned suspension performance straight out of the box. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption, and features toolless compression clickers for easy adjustment and fork covers to help prevent debris damage. The linkage-type rear suspension features a KYB® shock with cross-country focused damping characteristics to match the YZ450FX's refined chassis.

Ergonomics Designed for Control

The YZ450FX's slim, flat, compact body eases rider movement for improved control, including seamless, rounded features from seat edges and side covers to the narrow fuel tank and front shroud. The rider triangle is also designed to provide increased legroom between the seat and foot pegs for enhanced rider comfort.
