So as well as enduro engine and suspension settings, the FX has an 18 in rear wheel, bashplate, sealed O-ring chain, fuel level warning indicator and an aluminium sidestand. The Australian model comes with off road kit fitted as standard that makes it eligible for recreational registration in applicable states.

Potent Fuel-Injected Engine

A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give YZ450FX riders the ideal power spread in challenging off-road racing conditions.

Adjustable Engine Mapping

A handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner app—to account for changing track and weather conditions.

Bilateral beam frame

Yamaha’s bilateral beam aluminum frame features main spars, FX-specific engine mounts and an engine mounting position that centralises mass and provides an ideal balance between cornering feel and straight-line confidence.

Compact Body and Seat Design

The YZ450FX features stylish bodywork from tip to tail, including a large 8.2 litre, mass-centralised fuel tank, the body design is narrow for more comfortable knee grip and control feeling, while the narrower and lower seat gives the rider additional room to move aboard the machine.

Yamaha Power Tuner App

Yamaha’s exclusive Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike via the onboard WiFi system for the ultimate in track-side tuning.
