Chain DID 520 ERV7 (Racing)

The DID ERV7 chain is an evolution of the previous ERV3, which in the last decade has always been at the center of competitions. The ERV7 DID chain is used in MotoGP and SBK. The tensile strength has been improved by 3%, the life of the chain longer by 13% and finally a new X-Ring seal has been patented. The 520 pitch ERV7 chain is a chain with X2-Ring with exceptional smoothness, not exclusively for competitive use, although it is used on racing motorcycles of all displacements, its strength characteristics (breaking load 39.5 KN) and reliability (duration ratio 34.1) make it the ideal choice both for the most demanding rider and for the motorcyclist who wants to replace his chain with a narrower and smoother one. X-RING technology.

NOTES: open chain supplied with rivet closure (to be riveted with punch and hammer or with specific tool)
