2022 KAWASAKI KX450F - 70219

Kawasaki’s KX450 has topped the charts in Dirt Rider’s 450 Motocross Shootout since 2019. After receiving minor revisions in 2021, which included a new coned disc-spring hydraulic clutch, larger-diameter clutch plates with a revised friction material, new dry film lubricant coating on the piston skirt, a 1-1/8-inch handlebar, and bold new graphics (BNG), the 2022 model hits dealership floors with only BNG on the update list.
