D.I.D 525ZVM-X2 X-Ring Chain Black — 120 Links

D.I.D's flagship street chain — the same family of construction used by World Superbike and MotoAmerica teams, built for liter-class bikes and trackday riders who hammer their drive.

• X-Ring seals with low-friction profile reduce internal drag versus conventional O-Rings while keeping grease in place for 20,000+ miles of typical street use.
• Heat-treated alloy steel pins, plates, and bushings deliver the highest tensile strength in D.I.D's street range.
• Pre-stretched, pre-lubricated, and dimensionally checked end-to-end at the factory.
• The recommended chain for hypersport, superbike, and 1000cc+ touring platforms.
• Made in Japan; black or gold plating depending on link spec.

Intended use: sport, hypersport, track-capable.

Pitch / length: 525 pitch / 120 links (verify against your owner's manual; chains are cut down at install if longer than OEM spec).
