D.I.D Black X-Ring Chain 520ZVM-X

Superbike Strength – D.I.D’s ZVM-X Series has greater strength than the VX Series and is designed for heavyweight motorcycles with Tremendous Torque and Horsepower.
Longest Wear Life – The twisting action of the X-Ring® increases its sealing performance and its four contact points minimize power loss.
Quicker Response – The ZVM-X Series’ Direct Energy Transfer, born from our experience in MotoGP, means greater stretch resistance under load.
