At DMG Motorsports, we present the D.I.D 520VX3 120L Gold X-Ring Drive Chain (520VX3G120FB) — a premium 520-pitch chain built for riders who demand serious performance from their drivetrain. As one of the most trusted names in motorcycle chain technology, D.I.D engineered the VX3 series to deliver greater rigidity, smoother handling, reduced power loss, and quicker throttle response, making it the highest value chain in the entire D.I.D lineup. This gold-finished 120-link chain is a direct upgrade over previous VM series chains, offering superior longevity and dependable strength for street, dual-sport, and off-road machines up to 800cc.

Built around D.I.D's patented X-Ring seal technology, this chain's unique X-shaped ring design twists between the side plates to reduce friction, creating four contact points that seal in lubrication and keep out dirt far more effectively than standard O-ring designs. The result is a chain that runs cooler, smoother, and lasts significantly longer between services — a favorite among sport bike, dual-sport, and sport-touring riders looking to replace worn OEM chains with something built to handle real demands.
