520 MXR - 3D Drive Chain - Gold - 120 Links
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
