Strong Chain for Superbikes D.I.D’s ZVM-X Series has greater strength than the VX Series and is designed for heavy weight motorcycles with tremendous torque and horsepower. Longest Wear Life – The twisting action of the X-Ring® increases its sealing performance and its four contact points minimise power loss. Quicker Response – The ZVM-X Series’ high rigidity, born from our experience in MotoGP, means greater resistance to stretching under load. Features: High Rigidity: ‘RIGIDITY’ is D.I.D’s Original Concept born from years of experiences in MotoGP development Lower Rigidity = Pins flex robs horsepower. Higher Rigidity = Pins resist flexing reducing power loss Quicker response Reduced power loss Smoother handling X-Ring: D.I.D’s Patented X-Ring is superior to others. Half the power loss (compared with normal O-Ring) – D.I.D’s patented X-Ring construction reduces friction by twisting between the side plate instead of being squashed. The twisting action of the X-Ring disperses the pressure and minimises power loss. X-Ring Chain Endurance Performance (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 type seal. Solid Bush – Cold-Formed High-Precision Bushing: Solid Bushing chains have a high wear-resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness. Solid bushing = longer chain life This chain is a rivet link chain with 120 links.
