Description

The stock camshaft in your 2014-2015 YZ450F limits mid-range response and peak power delivery. The Hot Cams Stage 1 Intake Camshaft unlocks measurable gains in torque and horsepower while maintaining compatibility with your existing valve springs—no spring replacement needed. Whether you're chasing faster lap times or simply want sharper throttle response on the track, this is the bolt-on upgrade that delivers real performance without complexity.

Hot Cams' proprietary Improved Throttle Response (ITR) technology refines intake charge dynamics for snappier power delivery across the rev range. The drop-in design means installation takes minutes, not hours, making this one of the most efficient performance investments for any YZ450F owner.
