Tough terrain won’t stop us from winning. With championship-proven technology and tuning to take on every challenge, the KX450X motorcycle has what it takes to win outdoors. Get the off-road edge by riding the bike built to stay ahead of the rest.
The powerful fuel-injected 449cc liquid-cooled, 4-stroke single from the KX450 features finger-follower valve actuation and downdraft-style intake to deliver hard-hitting performance and a flat torque curve that facilitates getting on the gas.
Being able to restart an engine quickly during a race can mean the difference between keeping your lead, or having to fight your way back through the pack. An electric start makes restarting the engine as easy as pushing a button.
Like the KX450, a hydraulic clutch offers a direct feel and light lever action. The use of coned-disc springs contributes to lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching).
Lightweight and designed for the rigours of off-road riding, the ECU contains multiple programmable engine maps to offer riders an advantage on the race course. Using the provided DFI couplers, riders are able to easily switch from one to another of the three engine maps to suit riding conditions.
The well-balanced frame from the KX450 contributes to the KX450X’s light weight, light handling, and slim ergonomics.
High-performance suspension comes directly from the KX450. Spring rates and damping settings optimised for the cross-country scene offer increased feedback, especially when riding on aggressive trails.
The KX450 brake package optimised for cross-country riding includes a large-diameter ø270 mm front disc complemented by a ø240 mm disc at the rear, KX450-type front master cylinder and KX450X-specific pads, delivering strong stopping power and a high level of control.
The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control, and a smooth, flat rider interface.
Factory-style ø28.6 mm (1-1/8”) Renthal aluminium Fatbar is standard equipment. The thick handlebar helps reduce vibration and shocks transmitted to the rider and helps put the rider in a position that makes it easier to weigh the front wheel.
While the KX450 features F21”/R19” aluminium rims, the KX450X uses a F21”/R18” combination that facilitates putting power to the ground. Dunlop AT81 enduro-type tyres complement the KX450X-specific wheels and are well-suited to the situations encountered in cross-country riding.
KX factory-style skid plate and a convenient side stand are both standard equipment. The sturdy skid plate helps to protect the underside of the engine, and facilitates sliding over obstacles encountered on the trail, while the side stand comes in handy when stopping away from the paddock area.
