At DMG Motorsports, we present the D.I.D Pro VX-Ring Chain Master Link — the precision-engineered connecting link purpose-built for D.I.D's world-renowned VX3 Pro-Street X-Ring chain series. Whether you're replacing a worn link on the trail, the track, or the street, this is the only master link you should trust on your D.I.D VX3 chain. Engineered in Japan to the same exacting standards as the chain itself, this master link delivers the same hallmark rigidity and X-Ring seal performance that has made the VX Series D.I.D's most popular chain family for on- and off-road riders. Available in multiple pitches (520VX3, 428VX, 530VX) and in both clip-style (FJ type) and rivet-style (ZJ type) configurations, with your choice of natural steel or striking gold finish — this is the ideal replacement or spare link for any serious rider.

Features:

• Patented X-Ring Seal Technology: D.I.D's X-Ring cross-section reduces friction by twisting between the side plates to disperse pressure, seal in lubrication, and keep dirt out — delivering half the friction of a standard O-Ring chain.
• 32% Longer Chain Life: The 520VX3 master link is engineered for a chain boasting 32% longer service life than the VO Series, and 1.5–2× greater wear resistance than standard O-Ring chains.
• 7% Greater Rigidity Than VM Series: The VX Series is 7% more rigid than D.I.D's previous VM Series, meaning better power transfer from the engine to the ground and superior resistance to stretching, bowing, or warping under load.
• "Direct Energy Transfer" Technology: Increased chain rigidity delivers excellent throttle response, smoother handling, reduced power loss, and quicker acceleration feel.
• Average Tensile Strength of 8,210 lbs: Rated for motorcycles up to 800cc with a wear life index of 3,500 — built to handle the demands of today's high-performance street and off-road machines.
• Choice of Clip (FJ Type) or Rivet (ZJ Type): The FJ-type clip link is a press-fit design for convenient installation; the ZJ-type rivet link offers a fully peened, permanent connection for maximum security. A chain press/rivet tool is recommended for both types.
• Available in Natural or Gold Finish: Match or complement your VX3 chain with a clean natural steel look or bold gold colorway.
• Multiple Pitches Available: Compatible variants include 520VX3, 428VX (Pro-Street), and 530VX — covering a wide range of street, sport, dual-sport, and ATV applications.
• Made in Japan: Manufactured to D.I.D's legendary precision standards in Japan, ensuring an exact fit for VX3-series chains only. Not interchangeable with older V or VM series chains.
• Highest Value in the D.I.D Lineup: Represents the top of D.I.D's Pro-Street series, offering the best combination of performance, durability, and longevity in their chain range.
