FEATURES

Powerful 450cc Engine

Powerful 450cc Engine

The YZ450FX's advanced compact four-stroke engine is higher revving and produces broad power across the entire rev range. Additionally, ECU settings are tailored to suit the specific needs of trail riding and enduro competition.

Adjustable Engine Mapping

Adjustable Engine Mapping

The lightweight handlebar-mounted switchgear allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner App—to adjust for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response and slower revving characteristics for when traction is limited.

Cross County Features

Cross County Features

With the electric starting system, a 7.8L fuel tank, rugged plastic skid plate, 18-inch rear wheel and XC racing tyres, the YZ450FX is ready to win right out of the box.

Bilateral beam frame

Bilateral beam frame

Striking the perfect balance of precise cornering performance and handling stability, the aluminium bilateral beam frame consists of more than 10 different aluminium components welded together with YZ450FX-specific XC-tuned engine mounts. The result is a better handling machine with lighter feel, improved bump absorption and increased traction, allowing the rider to enter corners with greater confidence and more line choices.

Class Leading Suspension

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 while fork covers 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.

Yamaha Power Tuner App

Yamaha Power Tuner App

The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to an iOS® or Android® device, allowing owners to adjust air/fuel mixture and ignition timing, log race set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time, and more. The newest version of the app has been revised to be more user-friendly, with new features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction Control tuning, lap timer, and helpful engine and suspension tuning guides.
