At DMG Motorsports, we present the D.I.D 520VX3G140FB Pro-Street X-Ring Chain — a 140-link, gold-finish 520 pitch chain built for riders who want a serious upgrade over their OEM drive chain. Engineered by D.I.D, the world's leading name in motorcycle chains, the VX3 is the brand's most popular and widely used chain across on- and off-road bikes, delivering the ideal balance of strength, smoothness, and long-term durability for street, sport, dual-sport, and off-road applications up to 800cc.

This chain is built around D.I.D's patented X-Ring seal technology, which uses an X-shaped cross-section instead of a standard round O-ring. That design creates four contact points that seal in lubrication and keep out dirt far more effectively than conventional O-ring chains, while also cutting friction for smoother, more efficient power delivery. D.I.D also increased the rigidity of the VX3 platform to reduce flex through the chain, so power gets to the rear wheel more directly, with quicker throttle response and less wasted energy. Backed by an average tensile strength of 8,210 lbs and a wear life index of 3,500, this gold 140-link 520VX3 is a premium, race-proven upgrade ready to bolt on and perform.
