Find other: DID Chains
D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.
D.I.D has merged the Professional O-Ring V Series and the 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 the 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 maximize 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, and is now available at a new low O-ring chain price. 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.
- Compared with Normal O-ring chains, 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 minimizes power loss.
- Compared with Normal O-ring chains, 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.
