DID ERV3 or ZVM-X 520 chain conversion + sprockets

We use DID ERV3 520 pitch 120 link gold chain as it is the strongest chain we know of (and also the most expensive), steel countershaft sprockets and hard anodized aluminum rear sprockets supplied by either AFAM or Drive Systems to create a high quality, performance kit for most sportbike makes and models.

DID has recently come out with a brand new ZVM-X 520 chain that is rated to 1200cc's by their standards and is hailed as a "street" chain instead of a racing chain. It only weighs .3 of a lb more than the ERV3 520 and while I haven't actually used it I have sold a bunch of them and all the reports are coming back positive. If you would prefer one of the ZVM-X chains you can select it as an option below
