Description
Valve clearance directly impacts your CRF450R’s power delivery, fuel efficiency, and engine longevity. As your engine ages and components wear, shims shift and clearances drift—leaving performance on the table and risking valve damage. Hot Cams’ precision-engineered shims restore exact specifications, ensuring your top-end operates at peak efficiency with every ride.
This 5-pack gives you multiple shims to dial in clearance across your valve train or keep spares on hand for future adjustments. Each shim is manufactured to tight tolerances, guaranteeing consistent thickness and reliable fitment in your 2002-2012 CRF450R.
