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 is minimal chain drag, maximum horsepower, and uncompromising strength. A proprietary coating further reduces wear and corrosion, yielding a front sprocket unparalleled in the market

• Specially formulated coating retains strength and wear-resistance


• Internal broaching and precision machined to exact tolerances


• Core refined 655M13 nickel-chrome-molybdenum alloy steel


• Self-cleaning mud grooves prevent dirt build up


• Lightening holes reduce rotating weight
