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:

NEW FOR 2026

A new industry-first ECU lock function helps prevent theft and unauthorized engine start-up via a password-required lock.

New four-level Traction Control selectable within the Yamaha Power Tuner App maintains ideal rear wheel traction.

ENGINE

Compact, lightweight and durable clutch assembly yields smooth engagement and excellent feel.

The YZ450FX features a compact electric starter system to minimize restart delays and add convenience.

Tri-shaft transmission layout vertically stacks the transmission shafts for a lighter, more compact transmission.

A wide-ratio 5-speed transmission is geared for cross country, from tight technical single track to high speed open sections.

Lightweight handlebar-mounted switchgear allows the rider to quickly select between preloaded engine maps.

A convenient “Simple Tuning” slide bar further simplifies engine mapping within the Power Tuner App.

Yamaha's industry-leading Power Tuner App offers the ability to tune air/fuel mixture and ignition timing to suit rider preference.

An advanced fuel injection system uses a 44mm throttle body to ensure optimum fuel atomization and air/fuel calibration.

CHASSIS/SUSPENSION

Fully adjustable Speed Sensitive KYB® fork delivers exceptional balance between handling and bump absorption.

Premium Dunlop® Geomax MX33 tires achieve an ideal balance of traction and durability.

The YZ450FX's 18-inch rear wheel comes laced with a three-cross-spoke pattern for improved impact absorption and rider feel.

Premium Excel® wheels are strong, lightweight and reduce unsprung weight without sacrificing durability.

Wide foot pegs with lightweight aluminum alloy mounting brackets provide additional control and comfort.

Tapered aluminum handlebars are secured to four-position adjustable handlebar mounts.

The rider triangle is designed to provide increased legroom between the seat and foot pegs for enhanced rider comfort.

The YZ450FX's slim, flat, compact body eases rider movement for improved control.

ADDITIONAL FEATURES

Sleek air cleaner cover provides tool-free access to the air filter for simplified servicing.

Premium competition-inspired graphics are embedded to provide excellent durability and scratch resistance.

Other enduro-specific features include a 2.1-gallon fuel tank with warning indicator, composite engine guard and sealed drive chain.

Additional features include a PVC handlebar pad, seamless seat cover, updated switchgear and a folding aluminum kickstand.
