ProTaper Race Spec (RS) Front Sprockets are CNC machined and internally broached to precise tolerances from case-hardened, core-refined chromoly steel. Computer engineering ensures precise fitment, optimal weight savings and perfect balance. The result of this manufacturing process is minimal chain drag, maximum horsepower and uncompromising strength. A proprietary coating further reduces wear and corrosion, yielding a front sprocket that is unparalleled in the market.
