2026 Yamaha YZ450FX

Based on the benchmark-setting YZ450F motocrosser, the YZ450FX is designed to dominate cross country competition. With its lightweight chassis, powerful engine, exceptional rider ergonomics, and Yamaha's groundbreaking next-generation Power Tuner app, the YZ450FX is ready to make fast riders even

Features may include:

Light and compact, the 450cc engine maintains the YZ450F's exceptional pulling power and renowned ease-of-use, all while boosting the rev limit by 500 rpm for even more top-end power.

Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App is revised to be even more user-friendly. New features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with engine and suspension tuning guides.

The all-new 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.

A completely 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.

The all-new clutch design replaces the coil springs of the previous model with a new 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.

A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud. The rider triangle is also improved with increased legroom between the seat and footpegs, and revised handlebar position for a more natural posture and enhanced rider comfort.

Rear brake feel is improved by reducing the rigidity of the brake hose, providing a wider range of control at the pedal.
