Upgrade your Yamaha YZ85 with the ProTaper Part Number 038381 Front Sprocket. Crafted from core-refined 655M13 nickel-chrome-molybdenum alloy steel, this sprocket is CNC machined and internally broached to ensure precise fitment and optimal performance. The proprietary coating enhances wear resistance and corrosion protection, extending the sprocket's lifespan and maintaining peak efficiency over time. Designed for durability and lightweight performance, it reduces chain drag and maximizes horsepower, helping you achieve superior acceleration and power transfer. The self-cleaning mud grooves prevent dirt and debris buildup, ensuring consistent operation in rugged conditions. Lightening holes further decrease rotating weight, contributing to improved handling and responsiveness during intense riding sessions.
