DID's ERV3 is probably the ultimate race chain.  The attention to detail that has gone into every aspect of its design is incredible, and all of it aimed at getting the strongest possible chain at the absolute minimum cost in terms of weight and transmission losses.

Built For Professionals

D.I.D's 520ERV3 is the chosen chain of MotoGP, Superbike, and road racing teams alike.

Speed Counts

When tenths of a second and ounces count, the ERV3 is built with dimpled pinheads to reduce weight and push your bike to the speed you need.

Extreme Strength

With incredible tensile strength, the 520ERV3 is made to take a beating and is also a great option for off-road racing.

All chains are listed in standard lengths between 96 and 120 links.  Prices are based on 108 links with optional pricing for shorter or longer chains.  If you want a chain shorter than 96 links or longer than 120 links, please contact us for pricing on custom lengths.
