THE REDESIGNED 2021 CRF450R

Great handling starts with a superior frame, and we’ve made some big changes to our 2021 CRF450R’s chassis. First, it’s lighter—over a pound and a half lighter. By making the frame’s main spars narrower, we saved weight, but more important we made the chassis more responsive by reducing lateral rigidity 20 percent. The result is a bike that gets into, around, and out of corners faster.
