d.i.d. 520ERVT racing chain

A Racing

The 520ERVT is the top-of-the-line enduro chain, but it's strength, lightweight, and extended chain life makes it an ultimate racing chain.


Born from our original non-o-ring motocross chain, the ERVT boasts our patented X-Ring technology which provides less stretch, a higher tensile strength, and ultimately a longer lasting chain.

Yet Light

This is our lightest and longest lasting X-Ring chain in the 520 size.


  • The DID 520 ERVT Chain breaks down the concept of non o-ring chains and adds the benefits of an x-ring. By adjusting the materials the ERVT chain is 2% lighter and has a 15% longer lifespan, all the while maintaining the tensile strength.
  • 120 links
  • Suitable for 500cc max.
  • Average tensile strength of 8,440 lbs.
  • Includes clip style master link.
