ThreeD 520 MXR 3D Drive Chain

Description

• 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
