The ProTaper Race Spec (RS) Front Sprocket with 14 teeth is engineered for ultimate performance and durability in powersports applications. Crafted from core-refined 655M13 nickel-chrome-molybdenum alloy steel, this sprocket undergoes CNC machining and internal broaching to achieve precise tolerances that ensure optimal fitment and balance. Its proprietary coating enhances wear resistance and corrosion protection, extending the sprocket’s lifespan while maintaining peak performance. Designed to minimize chain drag, this sprocket helps maximize horsepower transfer, making it ideal for competitive riding or demanding off-road conditions. The self-cleaning mud grooves prevent dirt buildup, ensuring consistent operation even in muddy environments. Lightening holes reduce rotating weight, further improving acceleration and handling. This sprocket is compatible with several Yamaha YFM660R Raptor and YFZ450 models from 2001 to 2008, providing a reliable upgrade for enthusiasts seeking high-quality drivetrain components. Whether replacing worn parts or upgrading for improved performance, the ProTaper RS Front Sprocket offers a balanced combination of strength, precision, and weight savings for superior riding experience.
