At DMG Motorsports, we present the D.I.D CHAIN 520ERV7 120L GOLD/GOLD (520ERV7120ZB) — the flagship racing chain trusted by champions and privateers alike. This is D.I.D's top-of-the-line racing chain, engineered for all types of motorcycle racing, both on and off road, and built around the brand's patented X-Ring seal technology for a winning combination of strength, low friction, and long service life. Finished in eye-catching gold on both the inner and outer plates, this 120-link, 520-pitch chain delivers serious performance credibility — it's the same caliber of chain relied upon by factory teams competing in MotoGP, WSBK, MotoAmerica, Superbike, SX/MX, and off-road rally racing. Whether you're chasing lap times on the track or hammering through motocross whoops, this chain is built to keep pace with your machine.

Features:

• Top-of-the-line racing chain: Designed by D.I.D as their flagship performance chain for all types of motorcycle racing, on and off road.
• Patented X-Ring seal technology: The X-Ring twists between the side plates rather than squashing flat like a standard O-ring, dramatically improving sealing performance, retaining lubrication, and keeping contaminants out.
• Upgraded over the ERV3: Boasts a 3% higher tensile strength, a 13% longer chain life, and reduced friction thanks to X-Ring material improvements.
• High average tensile strength: Rated at approximately 8,800 lbs for confidence-inspiring durability under hard acceleration and racing loads.
• Gold/Gold finish: Gold-colored inner and outer plates for a premium, race-ready appearance that stands out on any bike.
• 120-link, 520 pitch configuration: Sized for a wide range of motorcycle applications requiring a 520 chain in the 120-link length.
• Proven at the highest levels of competition: Chosen by factory teams and top riders across MotoGP, WSBK, MotoAmerica, SX/MX, GNCC, and rally racing.
• Made in Japan: Manufactured by D.I.D, a leading global supplier of motorcycle drive chains known for precision and quality control.
