At DMG Motorsports, we present the D.I.D 520VX3 120L Natural Chain (520VX3X120FB) — a premium 520-pitch drive chain built for riders who demand smoother handling, crisper throttle response, and long-term durability. As the flagship of D.I.D's VX Series, this chain is engineered to be a serious upgrade over OEM equipment and delivers exceptional value across D.I.D's entire chain lineup. Whether you're running a street bike, sport bike, or off-road machine, the 520VX3 is built to handle the demands of daily riding and spirited performance alike.

This chain relies on D.I.D's patented X-Ring seal technology, which replaces the traditional round O-ring cross-section with an X-shaped design. That extra set of contact points seals in lubrication and keeps out dirt and grit far more effectively than standard O-rings, translating into significantly reduced friction and less power loss between the side plates. The result is a chain that not only lasts longer but also feels noticeably more responsive under acceleration.

Features:

• Patented X-Ring seal technology for superior lubrication retention and dirt exclusion
• Greater rigidity than previous D.I.D chains, reducing flex for smoother handling and quicker throttle response
• 32% longer chain life compared to D.I.D's VO Series thanks to improved X-Ring retention and durability
• Reduced power loss between side plates from the low-friction X-Ring design
• Highest value offering across the entire D.I.D chain series
• Superior longevity versus the previous VM series
• Rated for use on machines up to 800cc
• Average tensile strength of approximately 8,210 lbs
• 520 pitch, 120-link natural steel finish
• Includes a master link for straightforward installation
• Recommended as a direct upgrade from OEM chains on both street and off-road bikes
