At DMG Motorsports, we present the D.I.D 520VX3 Pro VX-Ring Chain — the pinnacle of street and off-road drive chain performance. As D.I.D's most popular and widely used chain for both on and off-road applications, the 520VX3 is a true upgrade over OEM, engineered to deliver smoother handling, sharper throttle response, and unmatched longevity. Powered by D.I.D's patented X-Ring seal technology, this chain delivers 32% longer chain life than the VO Series, halves the friction of standard O-Ring chains, and raises the bar with 7% greater rigidity over the previous VM series. Whether you're carving corners on the street or tackling demanding off-road terrain, the D.I.D 520VX3 is built for riders who refuse to compromise.

Features:

• Patented X-Ring Seal Technology: D.I.D's unique X-Ring cross-section design reduces friction by twisting between the side plates to disperse pressure, seal in lubrication, and keep out dirt — delivering 50% less power loss compared to standard O-Ring chains.
• 32% Longer Chain Life: Outlasts the VO Series by 32% and provides 1.5 to 2 times longer wear resistance compared to normal O-Ring chains, making it D.I.D's highest value chain series.
• 7% Greater Rigidity Than Previous VM Series: Increased rigidity reduces flex for better power transfer from engine to ground, greater resistance to stretching under load, smoother handling, and quicker throttle response.
• Direct Energy Transfer Technology: Enhanced chain rigidity enables excellent throttle response and superior resistance to stretching, bowing, or warping under real-world riding conditions.
• Average Tensile Strength of 8,210 lbs: Built to withstand the demands of today's high-performance motorcycles, rated for engines up to 800cc.
• 520 Pitch: Available in multiple link lengths (84L–150L) to fit a wide variety of street, dual sport, and off-road motorcycles.
• Two Color Options: Choose from classic Natural (steel) or eye-catching Gold finish to match your bike's style.
• Includes Rivet-Style Master Link: Clip-style master link sold separately. Note: master link is not interchangeable with older "V" and "VM" style chains.
• Made in Japan: Manufactured to D.I.D's exacting quality standards for reliability and durability mile after mile.
• Replaces V and VM Series: A direct upgrade over the Professional O-Ring V Series and the Premium X-Ring VM Series.
