Description
If you’re running a YFM660 Raptor in competition, your camshaft is the bridge between fuel and motion—and a poorly matched cam will leave horsepower on the table. Hot Cams’ stage-selectable designs let you dial in exactly where you want power delivery: low-end grunt for trail acceleration or top-end speed for open track. Both configurations drop in without modification, meaning you get measurable performance gains with minimal downtime.
