OVERVIEW

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

Being able to restart your engine quickly after a stall can make or break a race. Powered by a compact and lightweight Li-ion battery and supported by an automatic centrifugal decompression system, all it takes is the push of a button to start up.

The new Uni-Trak® rear suspension system features adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The result is optimal damping and rear-wheel traction.

The all-new KX™450 is the first KX™ model to feature 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 two 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™450 bike’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 check fuel volume and ignition timing, engine monitoring for checking engine metrics, a maintenance log for recording memo-style logs and many more useful functions.

A coned disc-spring hydraulic clutch offers light clutch pull and a wide engagement range. Large diameter plates provide enhanced fade resistance.

Based on feedback from Kawasaki's factory race teams, the KX™450 now features a larger-diameter rear hub. The hub’s increased rigidity allows loads to be transferred more directly to the ground, contributing to greater rear-end traction. New Dunlop MX34 front and rear tires offer increased longevity, improved ground contact contributing to better cornering performance in the front, and improved bump absorption performance and increased traction in the rear.

A redesigned lightweight aluminum perimeter frame accommodates the updates to the engine’s intake and exhaust systems, while delivering a high level of both light, nimble handling and a composed character. Optimized rigidity balance contributes to increased front-end feel that translates to improved cornering performance in a wider range of conditions.  

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

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

Newly designed shrouds, side panels, and rear fender are firmer and eliminate hooking points, further facilitating rider movement.

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

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