D.I.D 520ERV7 Racing Chain
Performance-driven, race-proven — the D.I.D 520ERV7 Racing Chain is engineered for riders who demand maximum strength, smooth power transfer, and long-lasting durability on the track or street.
-
High tensile strength: Precision-forged steel plates and rivets deliver superior load capacity for aggressive acceleration and high RPM use.
-
Low friction design: Optimized plate geometry and a hard chrome pin coating reduce friction and wear for improved efficiency and longer life.
-
Lightweight construction: 520 pitch balance offers reduced rotating mass without sacrificing durability — ideal for racing and high-performance setups.
-
Reliable sealing: Advanced O-ring/ X-ring options protect internal lubricant from dirt and debris for consistent performance under harsh conditions.
-
Precision fit: Factory-controlled tolerances ensure smooth engagement with sprockets, stable chainline, and reduced noise.
This chain is perfect for sportbikes, track machines, and competition builds where every gram and watt matters. Backed by D.I.D’s motorsport heritage, the 520ERV7 delivers race-level performance and confidence lap after lap.
