At DMG Motorsports, we present the D.I.D 520VX3 110L Gold X-Ring Chain (520VX3G110FB) — a premium 520-pitch drive chain built for riders who demand smoother power delivery and long-term durability from their street, dual-sport, or sport-touring machine. As part of D.I.D's top-selling VX Series, this chain combines the strengths of D.I.D's Professional V Series O-Ring chain and the popular VM Series X-Ring chain to deliver serious performance gains over stock. With a striking gold finish and 110-link length, it's a direct upgrade for riders looking to replace worn OEM chains with something built to handle real demands.

The 520VX3 is engineered around D.I.D's patented X-Ring seal technology, where the ring's X-shaped cross-section twists between the side plates instead of squashing flat like a conventional O-ring. This creates additional contact points that seal in lubrication and keep out dirt and grime far more effectively, cutting friction and power loss roughly in half compared to standard O-ring chains while extending wear life significantly. Combined with increased pin rigidity for reduced flex, riders get noticeably smoother handling and quicker throttle response, all backed by an average tensile strength rated at 8,210 lbs.

Features:

• Patented D.I.D X-Ring seal technology twists between side plates for lower friction, better lubrication retention, and superior dirt exclusion
• 32% longer chain life than D.I.D's previous VO Series thanks to the advanced X-Ring design
• Increased pin rigidity reduces chain flex for smoother handling, reduced power loss, and quicker throttle response
• Average tensile strength of 8,210 lbs, suitable for street, dual-sport, and off-road machines up to 800cc
• Superior longer life and improved seal performance compared to the previous VM series
• 110-link length in a bold gold finish, ideal for a wide range of sport bikes and dual-sports
• Highest value offering in the full D.I.D chain lineup
