CHAINS
520MXR 3D
  • 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
