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.
Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action.
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.
