2026 Yamaha YZ 450FX Single-Cylinder 450 - Jonesboro Cycle

2026 Yamaha YZ450FX

THE ULTIMATE WOODS RACER

The premier XC racer built to compete straight out of the box, the YZ450FX takes off-road performance to the next level.

Features may include:

High Performance 450cc Four-Stroke Engine

The YZ450FX's thrilling liquid-cooled DOHC four-stroke engine is renowned for its 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 groundbreaking next-generation 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 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 now 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.
