DID Chain - 520x120

DID 520 Chain

We carry two of DID's best 520 chains. Pick the one that fits how you ride:

Non O-Ring - 520ERT3
The non-sealed 520ERT3 is DID's #1 selling motocross chain, run by factory race teams like Monster Energy Kawasaki, Star Racing Yamaha, Honda HRC, Red Bull KTM, Factory HEP Suzuki and more. Thanks to its strength-to-weight ratio, it's the go-to chain across a wide range of racing disciplines, especially in the 250 class.

O-Ring (X-Ring Sealed) - 520ERVT
Strength. Chain life. Lightweight. Slim profile. The 520ERVT X-Ring sealed chain is arguably DID's most well-rounded, do-it-all chain. Part of their Exclusive Racing Series, it's built with off-road and rally-style racing in mind, delivering long chain life, a lightweight design, and serious strength.

Which one is right for you?
Go with the ERT3 if you want the lightest, race-bred motocross chain. Choose the ERVT if you want a sealed chain that lasts longer and does it all, on the track or off-road
