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 minimizes 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.

In developing the Pro-Street VX Series, D.I.D focused on improving chain “Rigidity”. Traditionally, “Tensile Strength” has been used to measure the strength of a chain. But Tensile Strength is only a laboratory measurement of a chain’s “breaking point”. Rigidity increases a chain's ability to withstand forces that occur in a rider’s real world experience. Rigidity increases 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, ZVM-X chains have D.I.D’s race proven low friction X-Rings. D.I.D’s PRO-Street VX Series Chains are a perfect match for your dual sport, sport bike or sport touring bike.
