DID · Part
The DID 520ERVT Chain is an off-road drive chain designed to bring X-Ring sealing benefits to the feel and concept of an original motocross-style non O-ring chain.
Its X-Ring design is intended to help keep lubrication sealed in while limiting dirt and mud from entering between the side plates.
The 520ERVT uses an X-Ring to help keep the chain sealed with lubrication while limiting dirt and mud from getting in-between the side plates.
Designed for off-road riding, the 520ERVT reworks the concept of the original motocross chain (non o-ring) by adding the benefits of an X-Ring. The result is aimed at riders looking for a drive chain that better manages lubrication sealing and contamination control in muddy conditions.
It is also described as more lightweight with longer chain life, making it a focused option for off-road drivetrain use.
This product is the DID 520ERVT Chain. It is intended for off-road use and is described as taking the original motocross chain concept (non o-ring) and adding the benefits of an X-Ring, with emphasis on lubrication sealing and limiting dirt and mud intrusion between side plates.
| 520ERVT breaks down the concept of the original motocross chain (non o-ring) and adds the benefits of an x-ring. |
| X-Ring helps keep your chain sealed with lubrication, limits dirt and mud from getting in-between the side plates, and only has 4 contact points with the plates which means less friction than the traditional O-Ring chain. |
| More lightweight and longer chain life. |
| By adjusting the materials, the 520ERVT is now 2% lighter and has a 15% longer lifespan, all while maintaining the tensile strength. |
