LIGHT NARROW FRAME Great handling starts with a superior frame, and that’s one place where the CRF450R chassis puts you out front. First, it’s light—over a pound and a half lighter than the previous generation’s. By making the frame’s main spars narrow, we save weight, but more importantly we make the chassis more responsive by fine-tuning the lateral rigidity. The result is a bike that gets into, around, and out of corners faster.

HYDRAULIC CLUTCH The CRF450R features the first hydraulically actuated dirtbike clutch we’ve offered outside of our works bikes. Made by Nissin, it’s the same design as in our Grand Prix MX machines, and performs better than third-party conversions. You get a clutch-lever pull that’s ten percent lighter at its peak, even though it’s paired with an eight-plate clutch. Plus, you’ll never have to worry about making a clutch-cable adjustment, even during the longest events.

SEALED AIRBOX AND FILTER Along with the special air filter, the airbox shape helps deliver more torque. You can access the airbox through the left number plate. And because the CRF450R’s filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.

EXCLUSIVE WORKS EDITION Simply stated, the best of the best.
