Description

If you're running a YZ250F and want measurable gains in low-end torque and throttle response, the Hot Cams Stage 1 Intake Camshaft is a bolt-on upgrade that delivers without requiring valve spring replacement. This cam's ITR technology sharpens your bike's acceleration and mid-range pull, making it an ideal choice for both trail riding and competitive scenarios where consistent power matters.

The Stage 1 profile is engineered to maximize torque delivery in the lower and mid-range RPM bands, giving you the snap you need when accelerating out of corners or technical sections. Combined with compatibility for stock valve springs, installation is straightforward—no expensive valvetrain modifications required.
