Yamaha YZ450FX

Description

The YZ450FX runs all the latest frame, suspension, engine and electronics upgrades found on the YZ450F – including the Yamaha’s exclusive smartphone tuning. We’ve developed the FX specifically for off-road competition. 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.

YZ450FX – when you want to push in the bush.

The compact, powerful YZ450FX engine includes all the same race-developed technologies of the class-defining YZ450F motocrosser, tuned for cross country performance. A host of go-fast innovations include steep valve angles, aggressive cam profiles, high-compression forged piston with low friction rings, high-flow intake and exhaust systems all thoughtfully packaged to optimise mass centralisation.

Yamaha’s smartphone tuning and bar-mounted map switch allows the rider to select power characteristics for changing riding conditions.
