D.I.D’s 520ERV3 is the chosen chain of MotoGP, Superbike, and road racing teams alike.
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.
With incredible tensile strength, the 520ERV3 is made to take a beating and is also a great option for off-road racing.
