KX ENGINE PERFORMANCE

Lead the Pack: One of the KX450’s greatest strengths is its engine, and that performance is available on the KX450X. In addition to the hard-hitting fuel-injected 449 cc liquid-cooled, 4-stroke single, the KX450X also shares the electric start, hydraulic clutch and the multi-map programmable race ECU of Kawasaki’s flagship motocrosser.

  • POWERFUL ENGINE - Serious Power Comes to the Cross-Country Scene: The powerful fuel-injected 449 cc liquid-cooled, 4-stroke single from the KX450 features finger-follower valve actuation (a valve train designed by Kawasaki’s World Superbike engineers) and downdraft-style intake to deliver hard-hitting performance and a flat torque curve that facilitates getting on the gas. Engine maps optimised for the cross-country scene deliver a broad spread of useable power.
  • ELECTRIC START - Reliable Starting: 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. Electric start makes restarting the engine as easy as pushing a button.
  • HYDRAULIC CLUTCH - Light & Responsive: Like the KX450, a hydraulic clutch offers direct feel and light lever action. Less play as the clutch heats up during heavy use results in more consistent feeling. 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).
  • SETTING-ADJUSTABLE ECU - Easy Engine Tuning: 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 plug-and-play style system is quick, easy and stress-free. Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.

KX CHASSIS PERFORMANCE

Light & Nimble: Complementing the powerful engine, the lean chassis from the KX450 offers light, nimble handling. High-grade suspension and brake components, and slim, adjustable ergonomics all add to off-road riding performance.

  • FRAME - Lightweight Aluminium Perimeter Frame: The well-balanced frame from the KX450 contributes to the KX450X’s light weight, light handling, and slim ergonomics.
  • SUSPENSION - Race-Ready Suspension: 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.
  • BRAKES - Large-Diameter Brakes: 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.
  • BODYWORK - Slim, Ergonomic Bodywork: The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control, and a smooth, flat rider interface.
  • ADJUSTABLE ERGONOMICS - Get the Perfect Fit: A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference. 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 weight the front wheel.

CROSS-COUNTRY COMPONENTS AND TUNING

Optimised Performance: The demands of cross-country courses are vastly different from those of supercross and motocross tracks. Accordingly, in addition to cross-country wheels and tyres, the KX450X’s suspension and brake systems have been optimised for the cross-country scene.

  • CROSS-COUNTRY WHEELS AND TYRES - Putting Power to the Ground: 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.
  • ESSENTIAL CROSS-COUNTRY EQUIPMENT - Protection & Convenience: 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.
