The KX450 has always been built with one goal in mind: to put riders on the top step of the podium. With over 40 years of KX heritage, Kawasaki delivers an unrivalled MX1 category machine with a stronger engine mounted in the leanest chassis to date. On top of that, the machine has many class defining features ensuring riders reach the podium in style.
Renthal Fatbar
A factory-style ø28.6 mm Renthal aluminium Fatbar, a popular aftermarket part, is now a standard feature.
Hydraulic Clutch
Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action.
KX FI Calibration Kit (Accessory)
KX FI Calibration Controller, a portable handheld calibration tool, enables riders to make changes to engine maps by plugging into the ECU without needing a PC or battery. Comes equipped with seven preset map settings.
Light Weight & Light, Nimble Handling
Complementing the powerful engine, light, nimble handling contributes to the KX450’s quick lap times. While the addition of electric start and the return to a coil-spring fork add weight, efforts were made to keep the weight gain to a minimum. The result is the KX450’s leanest chassis to date, and a highly-competitive, low overall weight of only 110.0 kg – a gain of only 1.3 kg.
Electric Start
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.
Setting-adjustable motocross ECU
Lightweight ECU was designed specifically to withstand the rigors of motocross racing. ECU contains three engine maps (plus a fourth for Launch Control Mode). Settings for the three maps can be reprogrammed with the optional KX FI Calibration Kit.
