After many hours of riding with the new chain and sprocket there was very little adjustment needed to the chain and no signs of wear on the sprocket. Great Buy!!!!!!!
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.
