At DMG Motorsports, we present the D.I.D CHAIN 520ERV7 114L GOLD/GOLD (520ERV7114ZB) — the flagship racing chain from the world's leading chain manufacturer, built for riders who demand maximum strength, minimum friction, and podium-proven durability. This 114-link, 520-pitch chain features D.I.D's patented X-Ring seal technology, an upgrade over the previous ERV3 generation, delivering greater wear resistance and reduced power loss for both street and race applications. Its eye-catching gold-on-gold finish adds a premium look to your drivetrain while standing up to the elements.

The 520ERV7 is trusted at the highest levels of competition. D.I.D's 520ERV7 is the chosen chain of road racing teams in MotoGP, WSBK, MotoAmerica, and it is also run by factory off-road and rally teams worldwide, a testament to its performance pedigree. Whether you're pushing hard on the track, tearing through off-road terrain, or simply want a stronger, smoother-running chain for the street, the 520ERV7 gives you the confidence to ride at the limit.

Features:

• Patented D.I.D X-Ring seal technology twists between side plates rather than squashing, reducing friction and improving sealing at four contact points versus standard O-rings
• Upgraded pin, bushing, and inner/outer plate materials over the previous ERV3 chain for increased wear resistance and a longer service life
• 3% higher tensile strength than the ERV3 thanks to stronger inner side plates and thicker pins, with an average tensile strength of 8,800 lbs
• Approximately 13% longer wear life compared to the ERV3 due to enhanced X-Ring durability
• Rated for engines up to 1,000cc, suitable for serious street, track, and off-road use
• 114-link length in a striking gold inner and outer plate finish for a premium, corrosion-resistant look
• Includes a rivet-style master link for a secure, race-ready connection
• Proven at the top level of motorsport, used by factory teams in MotoGP, WSBK, MotoAmerica, and premier off-road/rally series
