Pro Street VX -Series X-Ring – MADE IN JAPANIn 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 chains breaking point. Rigidity increases a chain’s ability to withstand forces that occur in a riders 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.Ds race proven low friction X-Rings. D.I.Ds PRO-Street VX Series Chains are a perfect match for your dual sport, sport bike or sport touring bike.Fitments:428VX max displacement 500cc520VX2 max displacement 750cc525VX max displacement 900cc530VX max displacement 1000cc Fits: Yamaha XVS250 DRAGSTAR 2003-2007
