2022 Kawasaki KX450

FACTORY-STYLE ENGINE COMPONENTS AND TUNING

Championship-proven Performance

Recognized as the most powerful motocrosser in the paddock, the KX450 boasts innovative engine technology inspired by Kawasaki’s race machines. Features like finger-follower valve actuation and a bridged-box bottom piston that contribute to its lofty performance are backed by electric start and a hydraulic clutch, further elevating its race-winning potential.

SERIOUSLY POWERFUL ENGINE

The high-acclaimed KX450 engine delivers hard-hitting power, while its flat torque curve makes it easy to get on the gas. Finger-follower valve actuation (a valve train designed by Kawasaki’s World Superbike engineers) enables large-diameter valves and aggressive cams. Downdraft-style intake and friction-reduction efforts (like a dry film lubricant on the piston skirt) further contribute to the high performance.

ELECTRIC START

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

The hydraulic clutch offers direct feel and light lever action. Revised construction using coned-disc springs results in lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching).

ADJUSTABLE MX ECU

LAUNCH CONTROL

Factory-style launch control system increases the chance of getting a good start by helping riders maximise grip when starting on a low-traction surface.

FACTORY-STYLE CHASSIS COMPONENTS AND TUNING

Light, Nimble Handling

Trimmed of all unnecessary material, this is the leanest KX450 chassis to date. Frame, suspension, brakes and ergonomics have all been optimized to make the KX450 even better equipped to turn quick lap times.

FRAME
Lightweight Aluminum Perimeter Frame
Complementing the powerful engine, light, nimble handling contributes to the KX450’s quick lap times. Thanks to extensive weight-reduction efforts, the lightweight aluminum perimeter frame contributes to a highly-competitive, low overall weight of only 110.2 kg.

SUSPENSION

Race-Ready Suspension

Handling suspension duties up front is a high-performance ø49 mm inverted coil-spring fork. The large-diameter inner tubes (the same size as on our factory racers) enable the use of large damping pistons, delivering smooth action and firm damping. At the rear, New Uni Trak rear suspension contributes to superb rear-wheel traction.

BRAKES

Strong Stopping Power

The oversized ø270 mm semi-floating front disc complemented by a ø250 mm disc at the rear deliver strong stopping power and a high level of control.The oversized ø270 mm semi-floating front disc complemented by a ø250 mm disc at the rear deliver 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.

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 aluminum Fatbar helps reduce vibration and shocks transmitted to the rider, while a lower, closer grip position helps put the rider in a position that makes it easier to weight the front wheel.
