Developed by working closely with top-level professional race teams and input from testing professionals like Kris Keefer at Keefer Inc. Testing. We came up with a camshaft that puts the power right where it is needed. The 2017-2020 CRF 450R is already fast, but by getting that power in the right spot it is important. The goal was to be able to make the power and torque range more broad and usable so you can get that low end grunt out of the corners but still make the power pull longer in each gear. This cam does exactly that, we highly recommend installing our intake valve springs for this camshaft.
