2020 KX450, LIGHT & FAST 450cc MOTOCROSSER
To maintain its edge in this fiercely competitive class, the 2020 KX450 benefits from an engine mounted in its leanest chassis to date, enabling it to turn even quicker lap times, and make it the most powerful machine in the paddock. Complementing its already high performance, with a number of features – including finger-follower valve actuation, electric start and a hydraulic clutch, – further elevate its race-winning potential.
Designed with mid-level to expert riders in mind, the KX450 motorcycle has always been built with one goal in mind: to put riders on the top step of the podium. And for over 40 years KX brand motocrossers have been extremely successful at doing just that.
