The DID 520ERVT X-Ring Drive Chain breaks away from the traditional non O-ring motocross chain concept by keeping the lightweight feel while adding the sealing benefits of an X-Ring. The result is a chain that stays lubricated longer, resists dirt and mud ingress, and runs with less friction than a standard O-ring design—ideal for riders who want consistent performance and extended service life.
If you ride in dusty, muddy, or high-wear off-road conditions, this chain helps reduce drivetrain wear and cuts down on maintenance by keeping lubrication sealed where it belongs. DID’s updated material tuning makes the 520ERVT 2% lighter and delivers a 15% longer lifespan while maintaining strong tensile strength for confident power delivery.
Key features:
✅ 520ERVT updates the original lightweight MX chain concept by adding X-Ring benefits
✅ X-Ring sealing helps keep lubrication in and limits dirt/mud between side plates
✅ Only 4 contact points vs traditional O-ring = reduced friction and smoother running
Benefits of use:
🔹 Longer chain life with better sealing in harsh off-road environments
🔹 Lower friction for efficient power transfer and improved drivetrain smoothness
🔹 Lightweight build without sacrificing strength—great for MX and enduro riders
