DiD ERV3 520 X-Ring Motorcycle Chain

[ridersdiscount]

DiD ERV3 chains are one of our most popular items for street and track use. The gold-colored steel plates look nice and they’re relatively light for a 520 pitch chain. The ERV3 uses X-ring seal technology which has unique properties for efficiently retaining lubricant. This lubricant retention reduces friction, increases chain life and transfers power from the engine to the rear wheel more efficiently than traditional o-ring type motorcycle chains. This chain is strong too and when measured against the older DiD ERV2 (also a great chain) the ERV3 has increased tensile strength by 5%. Tensile strength is a measure of a chain’s absolute strength in which the chain is pulled upon until it breaks. In this case, the DiD chain had an average failure point of 8,660lbs – more than four tons! Fatigue strength is another critical factor by which chains are judged. This number is indicative of a chain’s survivability when its expected normal operating load is continuously breached and the ERV3 yet gain outshines the older ‘2 model by 15%.

We have a drawer full of DiD ERV3 chains in the shop for use on all of our bikes for the reasons mentioned above – they look great, they last and they’re reliable.
