FEATURING:
Powerful 449 cc 4-stroke engine
Downdraft intake, cylinder with straight intake/exhaust ports, and centrally positioned exhaust
Handlebar-mounted traction control and power mode switches
Smartphone connectivity: change engine mapping with your smartphone phone
Brembo brake components
ERGO-FIT adjustable ergonomics
Off-road ready suspension, F21"/R18" wheels and off-road tYres, side stand
The KX450X’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.
FACTORY-STYLE CHASSIS COMPONENTS AND TUNING
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.
CROSS-COUNTRY COMPONENTS AND TUNING
Optimised Performance
Cross-country-specific tuning for the suspension, complemented by a 21”/18” wheel combination fitted with enduro-type tyres, and convenient standard features like a side stand make the new KX450X even more attractive for cross-country competitors.
ADVANCED TECH AT YOUR FINGERTIPS
Power Modes, Kawasaki Traction Control, and Launch Control Mode Accessed from the Left Handle Switches
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.
