ThreeD 520 MXR 3D Drive Chain Gold 116 Links 520MXR3D116G

Precise forging process leads to a stiff chain for better acceleration and more efficient engine work. Lightening hole allows for a lighter chain without compromising strength while removing mud and dispersing heat more efficiently. Improvement in transmission efficiency. Special pins with holes in both ends allow the chain to be lightened. Edge-cut inner plate reduces friction and allows for smooth engagement with sprocket. Non-sealed to reduce as much friction as possible. Chromium Carbide pin surface coating increases hardness and reduces chain wear. For use with 125cc-500cc motocross bikes
