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.
The D.I.D X-ring® is superior to other types of O-ring designs; it has half the power loss and 1.5 to 2 times the wear resistance of a normal O-ring chain. 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. 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.
