The KX legacy created a long line of champions. The drive to produce more has not slowed down. Our all-new flagship race machine, the KX450, offers next-level engineering and power to dominate the track. Over the decades, we’ve learned what it takes to win and stay on top. The KX450 embodies this legacy to the fullest.

Factory-Style Engine Components and Tuning

The KX450’s engine has always been a strength, but Kawasaki engineers found a way to make it even stronger. Offering increased performance across the rev-range, the more potent new engine is backed by a host of features like Launch Control Mode, electric start and a hydraulic clutch, proven to give racers an edge on the track.

Factory-Style Chassis and Tuning

Complementing its acclaimed straight-line performance and nimble handling, a redesigned frame with optimized rigidity balance enables improved cornering performance that remains consistent across a wide range of conditions, while more centralized mass also contributes to the improved handling performance. Premium Brembo brake components and ODI Lock-On grips add to both performance and brand recognition.

Advanced Tech at Your Fingertips

The new KX450 and KX450X are the first KX models to offer Power Mode selection and Kawasaki Traction Control at the push of a button. And with smartphone connectivity, riders can adjust engine maps right from their smartphones (another KX first that eliminates the need for accessory equipment using the smartphone application “RIDEOLOGY THE APP KX”).

Slim, Ergonomic Bodywork

Already highly acclaimed for their slim ergonomics, the KX450 and KX450X receive redesigned bodywork that offers an even smoother rider interface. Newly designed shrouds, side covers, and rear fender are firmer and eliminate hooking points, further facilitating rider movement.

Holeshot Advantage: Launch Control Mode

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

Hydraulic Clutch

Compared to a conventional clutch, the hydraulic clutch offers more direct feel and lighter lever action. Less play as the clutch heats up during heavy use results in more consistent feeling.

Lightweight Aluminium Perimeter Frame

A redesigned 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.

Race-Ready Suspension

Factory-style Ø 49 mm inverted coil-spring front fork and New Uni-Trak rear suspension offer race-ready suspension performance and adjustability to let riders tune their settings to suit conditions.

Quick-Release Side Cover

Side cover can be removed without tools, facilitating access to the air filter element.

Adjustable Ergonomics

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.

Even Stronger Engine

Downdraft intake layout and symmetrically aligned intake and exhaust deliver increased power across the rev-range. Redesigned intake offers a much straighter route for air-fuel mix to enter the cylinder, while a centrally positioned exhaust port lines up with the intake for high airflow efficiency, both contributing to increased performance.

Power Modes

Using the Mode (M) button on the left handlebar, riders can quickly and easily switch between two engine maps (Normal, Mild response) provided in the ECU.

Kawasaki TRaction Control (KTRC)

Using the Traction (T) button on the left handlebar, riders can quickly and easily select from two levels (Weak, Strong) of traction control to suit conditions and preference. Riders may also elect to turn the system off.

ODI Lock-On Grips

Medium-compound ODI Lock-On Grips offer excellent grip feel, while their screw-type fastening system greatly facilitates the task of swapping grips.

High-Performance Brembo Brake System

Revised brake components include drilled Braking/Sunstar discs (Ø 270 mm/ Ø 240 mm) paired with a Brembo caliper and master cylinder at the front and a Nissin caliper and master cylinder at the rear. The high-performance system offers increased controllability on the brakes, contributing to enhanced corner entry.

Smartphone Connectivity

Using the smartphone application “RIDEOLOGY THE APP KX,” riders can access and adjust their bike’s engine maps. Functionality (adjusting fuel and ignition timing) is similar to that offered by the accessory KX FI Calibration Kit used with previous models. Maintenance logs are also available.
