Description
If you’re running a YFZ450 and want measurable gains in both mid-range punch and top-end power, a quality exhaust camshaft swap is one of the highest-ROI modifications you can make. The Hot Cams Stage 3 is engineered to optimize valve timing and lift across the entire RPM band, delivering the throttle response and horsepower your engine demands without requiring engine work. This is a bolt-on upgrade that separates serious racers from casual riders.
The Stage 3 design incorporates Hot Cams’ Improved Throttle Response (ITR) technology, which sharpens throttle action and eliminates dead zones in the lower and mid-range. You’ll feel the difference immediately on the track—crisper power delivery, faster spool-up, and noticeable gains in the 4,000–8,000 RPM sweet spot where most racing happens.
