D.I.D's 520ERV7 is the chosen chain of road racing teams in MotoGP, WSBK, MotoAmerica and BSB
Upgraded from the 520ERV3, the 520ERV7 boasts a 3% higher tensile strength, a 13% longer chain life, and less friction due to X-Ring material improvements
The ERV7 is our top-of-the-line racing chain created for MotoGP and is now utilized by professionals in rally, enduro, and sx/mx. When tenths of a second and ounces matter, the ERV7 has dimpled pin heads to reduce weight without compromising the strength of the chain. Championship quality for the SERIOUS racer.
