The Bike that Builds Champions

Our all-new flagship race machine, the KX450 motorcycle, 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.

CHAMPIONSHIP-PROVEN PERFORMANCE

The KX450’s engine has always been a strength, but Kawasaki engineers found a way to make it even stronger. Offering smoother low-end torque characteristics and a stronger over-run, the more potent new engine is backed by a host of features like electric start and a hydraulic clutch.

LIGHT & AGILE

Complementing its acclaimed straight-line performance and nimble handling, a redesigned frame with optimised rigidity balance enables improved cornering performance that remains consistent across a wide range of conditions, while more centralised 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

Complementing an updated Launch Control Mode, 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.

RELIABLE STARTING

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.

LIGHT & RESPONSIVE

A hydraulic clutch offers direct feel and light lever action. Less play as the clutch heats up during heavy use results in more consistent feeling. The use of coned-disc springs contributes to lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching).

SUSPENSION

Factory-style ø49 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.

HIGH-PERFORMANCE BREMBO BRAKE SYSTEM

Revised brake components include drilled Braking/Sunstar discs (ø270/240 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.

EASY ENGINE TUNING

Using the smartphone application “RIDEOLOGY THE APP KX,” riders are able to 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 and setup logs are also available.
