ThreeD - 520MXR3D-120G - 520 MXR - 3D Drive Chain - Gold - 120 Links
The ThreeD 520MXR3D-120G is a 120-link 520 MXR 3D drive chain in Gold, built with precise forging for a stiff chain that improves acceleration and engine efficiency, lightening holes that reduce weight without sacrificing strength while removing mud and dispersing heat, and a non-sealed design with chromium carbide-coated pins to minimize friction — engineered for 125cc–500cc off-road bikes.
Features
- 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
