THE BIKE THAT BUILDS CHAMPIONS

A flat torque curve makes it easy to get on the gas sooner, delivering smooth and powerful acceleration to pass the competition and keep you ahead of the pack.

Engine maps are optimized for cross-country racing and are tunable using RIDEOLOGY THE APP KX™ on your smartphone. By tuning engine maps, the rider can change power delivery to best suit riding conditions and personal preference.

Fast, reliable starting can make or break your race, from nailing that dead-engine start to get you out front early to restarting the engine after stalling. Electric start makes it as easy as pushing a button.

The Uni-Trak® rear suspension system features a Showa shock with adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The linkage system mounts the suspension arm below the swingarm, allowing a long rear suspension stroke for precise tuning. As a result, riders can optimize damping and rear-wheel traction to suit conditions and personal preference.

The KX™450X motorcycle features Kawasaki TRaction Control (KTRC) at the push of a button. By using the traction button (T) on the left handlebar, riders can quickly and easily select from 2 levels (Weak or Strong) of traction control to suit riding conditions and preference. Riders may also elect to turn the system off.

A factory-style launch control system helps put the KX™450X motorcycle’s power to the ground for maximum acceleration. By pushing the Mode and Traction buttons simultaneously, riders activate the launch control system which is designed to deliver efficient race starts in low-traction conditions, making the holeshot yours for the taking.

Thanks to smartphone connectivity, riders can adjust engine mapping straight from their phones via RIDEOLOGY THE APP KX™, without the need for extra equipment. The app also provides KX™ FI Calibration to fine-tune fueling and ignition timing, engine monitoring for checking engine metrics, and a maintenance log for recording memo-style logs —plus many more useful functions.

A coned disc-spring hydraulic clutch offers light clutch pull and a wide engagement range. Compared to a conventional clutch, the hydraulic clutch offers more direct feel and lighter lever actuation, while large-diameter plates provide enhanced fade resistance.

The KX™450X motorcycle is built to meet the tough demands of cross-country racing. Cross-country wheels (21-in front/18-in rear) are paired with specific Dunlop Geomax AT81 tires developed for GNCC racing.

A lightweight aluminum perimeter frame delivers a high level of both light, nimble handling and a composed character. Optimized rigidity balance contributes to precise front-end feel that translates to sharp cornering performance in a wide range of conditions. 

Wide footpegs ensure excellent grip for optimum comfort and control and make it easy to weight the pegs.

Find your best performance with the Kawasaki ERGO-FIT® advantage. Four handlebar positions and 2 footpeg positions allow you to tailor the KX™450X cross-country motorcycle to your body size, riding style, and preference.

Sleek design of the shrouds, side panels, and rear fender eliminate hooking points, further facilitating rider movement.

A factory-style aluminum Renthal® Fatbar® handlebar comes standard. Medium-compound ODI lock-on grips offer excellent grip feel, while their screw-type fastening system greatly facilitates the task of swapping grips.

A quick-release side cover can be removed without tools, allowing for easy access to the air filter element.
