Works great on R1, looks good too!
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's engineers are continuously improving chain designs in order to handle the tremendous horsepower loads of today's high performance motorcycles. In developing the new DID ZVM-X series, D.I.D focused on "Rigidity." Traditionally, "Tensile Strength" has been the bench-mark to indicate overall strength, but tensile strength is only a laboratory static measurement of a chain's fracture point. Rigidity, on the other hand, is the ability of a chain to withstand the forces that occur in the real world that riders experience. Increased rigidity means better power transfer from the engine to the ground, greater resistance to stretching under load, and overall improved performance that meets the demands of the current high-power bikes and the people who ride them.
Half the Power Loss - 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.
1.5 to 2 Times Longer Wear Resistance - 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.
