The YZ450FX is developed from Yamaha’s flagship motocross model YZ450F with many added features and unique settings that make the YZ450FX the ultimate off-road racer.
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.
The YZ450FX’s advanced aluminium bilateral beam frame features precisely tuned flex characteristics that give riders the ultimate combination of cornering performance, traction feel and bump
Yamaha’s spring-type KYB forks with refined, speed sensitive damping and linkage-type rear suspension featuring a KYB shock endow the YZ450FX with its renowned, class-defining suspension performance straight out of the box.
A rigid front caliper and compact rear caliper work with aggressive pad compounds and lightweight rotors to provide exceptional braking power and controllability, dissipate heat more efficiently, and reduce unsprung weight.
The YZ450FX includes a range of cross country specific upgrades compared to the YZ450F including off-road ECU settings, KYB suspension with specially tuned damping, a composite engine guard, 18- inch rear wheel, enduro-specific Dunlop Geomax MX3S tyres, sealed O-ring chain, fuel level warning indicator, new MY23 headlight and a folding aluminium kickstand.
