At DMG Motorsports, we present the D.I.D 520VX3 130L Natural (520VX3X130FB) — a professional-grade X-Ring drive chain built for riders who demand durability, efficiency, and a responsive feel from their motorcycle's drivetrain. As D.I.D's most popular and widely used chain for both on and off-road bikes, the 520VX3 upgrades any street, sport, dual-sport, or off-road machine up to 800cc with technology proven on the world's top Superbikes. This 130-link natural finish chain is ready to bolt on and deliver mile after mile of confidence-inspiring performance.

Built around D.I.D's patented X-Ring seal technology, this chain replaces the traditional circular O-Ring cross-section with a unique X-shaped design that creates four contact points instead of two. The result is a chain that seals in lubrication and keeps out dirt and grime far more effectively than conventional O-Ring chains, while cutting friction significantly to free up power at the rear wheel. D.I.D also focused heavily on rigidity in developing the VX Series, since tensile strength alone only measures a chain's static breaking point rather than its real-world performance. Increased chain rigidity means less flex, better power transfer, and noticeably quicker throttle response — exactly what riders need when pushing a bike hard.

Features:

• Patented D.I.D X-Ring seal technology reduces friction with four contact points that seal in lubricant and block out dirt
• Greater rigidity delivers smoother handling, reduced power loss, and quicker throttle response
• Up to 32% longer chain life than D.I.D's VO Series, and noticeably superior longevity versus previous VM series chains
• Up to 2x longer wear life than standard O-Ring chains thanks to lower-friction X-Ring construction
• Average tensile strength rated at 8,210 lbs with a chain life index of 3,500
• Rated for street, ATV, and off-road use on motorcycles up to 800cc
• 130 links, 520 pitch, natural steel finish
• Pin length of 0.736 in. and pin diameter of 0.206 in., with 2mm inner and outer plate thickness
• Weighs approximately 3.35 lbs per 100 links for a strong yet lightweight build
• Includes a clip-style master link for straightforward installation
