All D.I.D. premium chains are stocked in 100 foot rolls and any length can be cut upon request.

D.I.D.'s patented X'ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O'rings and other maker's modified O'rings have squashed points that increase friction. The twisting action of the X'ring disperses the pressure and minimizes power loss. D.I.D. has redesigned the shape of the X'ring to maximize wear resistance of the 520ZVMX, 525ZVM2 and 530ZVMX chains. Super Street X2-Ring chains have also been beefed up in tensile strength to make them the ultimate chains for today's high performance sport and sport touring motorcycles.

520ZVMX is one of the strongest 520 pitch chains on the market and rated to 1200cc's. Works great on all high horsepower applications including ATV's. Each chain includes one rivet style master link.
