Model: chain1Part Number: DID520ERVGGBrand: DID
Availability:
The DID ERV7 chain is used by more Factory Race Moto GP, WSB and BSB Teams around the world than any other motorcycle chain. It is the worlds lowest friction race chain, less friction equals more power!
Each chain is supplied with 'Two' Rivet Links, additional links can be ordered at the same time !
The 520ERV7 is an upgrade that will replace the 520ERV3. Quite a bit of a jump from 3-7, but that is a story for another time. It has been over a decade since the 520ERV3 was introduced, so the 520ERV7 will see significant upgrades, including stronger inner plates, resulting in a 3% higher tensile strength, and a greater chain life, which is increased by 13% due to material upgrades with our patented X-Ring seal. The ERV7 will be slightly heavier than the ERV3 at 3.41 lbs per 100 links !
