D.I.D 520ZVM-X Heavy Duty Super Street Chain - 140 Links - GOLD 

The D.I.D ZVM-X Series utilizes our patented X-Ring seal and has greater strength than the VX Series and is designed for heavyweight motorcycles with tremendous torque and horsepower. The twisting action of the X-Ring® increases its sealing performance and its four contact points minimizes power loss. The ZVM-X Series’ Direct Energy Transfer, born from our experience in MotoGP, means greater stretch resistance under load.

NOTE: 520 Sprockets Conversion is a MUST to use this Chain
