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.

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.

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* *

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.

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.

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.

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.

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.

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

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

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.

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.

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.

Being able to restart an engine quickly after a spill 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.

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

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.

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.
