At DMG Motorsports, we present the D.I.D CHAIN 520ERV7 118L GOLD/GOLD (520ERV7118ZB) — the flagship racing chain from the world's most trusted drive chain manufacturer. The 520ERV7 is the top-of-the-line racing chain for all types of motorcycle racing, on and off road, built around D.I.D's patented X-Ring seal technology that makes it a top performing racing chain. It's the chosen chain of road racing teams in MotoGP, WSBK, and MotoAmerica, trusted by riders such as Valentino Rossi, Andrea Dovizioso, and Alex Rins. This gold-on-gold, 118-link chain is ready to bolt on and deliver race-proven performance whether you're on the track or the street. DMG Motorsports is proud to offer this genuine D.I.D chain for riders who demand uncompromising strength, low friction, and long service life.

Features:

• Boasts a 3% higher tensile strength versus the previous ERV3 generation, along with a 13% longer chain life and reduced friction thanks to X-Ring material improvements
• D.I.D's patented X-ring construction reduces friction by twisting between the side plates instead of squashing like ordinary O-rings, and its four contact points greatly increase sealing performance
• This design keeps dirt out and lubrication in far better than conventional O-rings, giving X-rings the greatest wear resistance of any O-ring or non-O-ring chain type
• Average tensile strength rated at 8,800 lbs, with a manufacturer rating up to 1000cc engines
• Weighs approximately 3.41 lbs per 100 links with a maximum chain width of 0.752 inches
• 118-link length in a striking Gold/Gold finish, complete with a rivet-style (ZJ) master link
• Manufactured by D.I.D, whose brand drive chains and aluminum rims are produced in Kaga, Ishikawa prefecture, Japan and supplied through motorcycle dealers worldwide
• This focus on uncompromising quality has made D.I.D a top original parts supplier for Japanese and European motorcycle manufacturers
• Great for club racing or top-level competition, used by many AMA, MotoAmerica, WSBK, and MotoGP race teams
