The worlds no.1 motorcycle and quad chain

D.I.D's X-Ring chain is designed for high performance motorcycles. Their patented X-Ring construction creates a chain that is low in friction and high in wear resistance. D.I.D's sealed chains incorporate D.I.D's uniquely designed seal-rings which seal D.I.D's special "V" grease in the pin/bushing area and lock dirt out. They are expected to last at least ten times longer than standard chains without significant wear elongation under satisfactory maintenance.

Coming soon:

• D.I.D 428 Pitch Drive Chains
• D.I.D 520 Pitch Drive Chains
• D.I.D 525 Pitch Drive Chains
• D.I.D 530 Pitch Drive Chains
• D.I.D 532 Pitch Drive Chains
• D.I.D 630 Pitch Drive Chains
• D.I.D 632 Pitch Drive Chains

Since motorcycle drive chains will be used under the most rigorous conditions, the ultimate technologies provide resistance to wear, durability against fatigue, and quiet operation. D.I.D motorcycle chains are trusted and highly rated-that's why D.I.D's chains are used in major motorcycle races, such as Moto GP, World Endurance Championship, Motocross, and the Paris-Dakar Rally. D.I.D is the number 1 global brand for power train technology

D.I.D's High Performance X-Ring® for Street Bikes
D.I.D X-RING® IS SUPERIOR TO OTHER TYPES OF O-RING DESIGNS

Half the Power Loss
(Compared with Normal O-Ring)
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 makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimises power loss.

1.5 to 2 Times Longer Wear Resistance
(Compared with Normal O-Ring)
The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.

New Pro-Street X-Ring® VX Series

All New; D.I.D has merged our Professional O-Ring V Series and our top selling Premium X-Ring® VM Series into “ONE” New Pro-Street X-Ring® VX Series. Created from the severe demands of today’s top World Superbikes, D.I.D is proud to introduce this New high performance VX Series. In developing this new series, D.I.D focused on improving “Rigidity”. Traditionally, “Tensile Strength” has been used to indicate the overall strength of a chain. But Tensile Strength is only a laboratory static measurement of a chain’s “breaking point”. Rigidity, on the other hand, is the ability of a chain to withstand forces that occur in a rider’s real world experience. Increased rigidity means better power transfer from the engine to the ground and greater resistance to stretching under load. This translates into smooth handling and quicker response time. To maximise performance, D.I.D’s race proven X-Ring® design delivers overall improved performance that meets the demands of today’s high-performance machines. The VX Series is the ultimate in performance and durability, now available at a new low O-Ring Chain Price. VX Series Chains are available in 428VX, 520VX2, 525VX and 530VX sizes. D.I.D’s New PRO-Street X-Ring® VX Series Chains are a perfect match for your dual sport, sport bike or sport touring bike.
