The D.I.D 520ERVT 25-foot gold chain is a premium long-length drive chain engineered for enduro riding, motocross, off-road competition, and demanding racing applications. Built in the 520 size, this chain combines low weight with high tensile strength and extended service life. Its gold finish adds a clean, distinctive appearance while supporting the performance-focused design associated with D.I.D racing chains.
Developed from D.I.D’s original non-O-ring motocross chain, the 520ERVT uses patented X-Ring technology to help reduce friction and minimize chain stretch. The sealed X-Ring design helps retain lubrication and limit contamination at the link points, supporting smoother operation and longer wear life than a conventional non-sealed chain. This makes the chain well suited to riders who need consistent power transfer and durability during intense off-road use.
The 25-foot continuous length is suitable for custom builds, professional race preparation, replacement-chain programs, and applications requiring chain to be cut to a specific length. Fitment depends on the motorcycle’s required chain size, pitch, sprocket configuration, and final chain length; confirm that your application calls for a 520 chain before installation. This product is manufactured by D.I.D and is identified by manufacturer and vendor part number 520ERVT25FT.
