D.I.D. 520VX3X130FB 520 VX3 X-Ring Drive Chain 130 Links Natural

The D.I.D. 520VX3 Pro-Street X-Ring Chain is a premium 520-pitch drive chain with 130 links, designed as a significant performance upgrade over stock OEM chains for motorcycles up to 800cc. Made in Japan, the VX3 is D.I.D.'s most popular and widely used chain for both on-road and off-road applications.

At the heart of this chain is D.I.D.'s patented X-Ring seal technology, which sets it apart from conventional O-Ring designs. The X-Ring reduces friction by twisting between the side plates rather than being compressed, resulting in just half the friction of a standard O-Ring chain. Four contact points provide exceptional sealing — keeping lubrication in and contaminants out — for dramatically extended chain life.

Key Features:

• 32% longer chain life than the D.I.D. VO Series thanks to patented X-Ring technology
• Average tensile strength of 8,210 lbs — rated for motorcycles up to 800cc
• 7% more rigid than D.I.D.'s previous VM Series chains for better power transfer and reduced stretch under load
• 1.5 to 2 times longer wear resistance compared to standard O-Ring chains
• Wear life index of 3,500
• Pin length: 0.736 in. | Pin diameter: 0.206 in.
• Inner and outer plate thickness: 2 mm
• Weight per 100 links: 3.35 lbs
• Includes a clip-type master link; rivet master link available separately
• Available in natural (steel) finish

The D.I.D. 520VX3 is the ideal chain upgrade for dual sport, sport bike, and sport touring riders seeking maximum durability, smooth power delivery, and responsive throttle feel. Note: The included master link is not interchangeable with older D.I.D. "V" and "VM" style chains.
