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: Honda CBR250RR 1990 1992-1993 CT200 AUTOAG 1984 1986-1987 1989 1993 MSX125 Grom 2015-2018 2020 TRX90 2WD 1999-2002 VTR250 1999-2000 Husqvarna TC 85 2023 TC 85 BW 2023 TC85 Big Wheel 2014-2021 TC85 Small Wheel 2014-2021 KTM SX 85 2023 SX 85 BW 2023 Kawasaki KLX150L 2014-2015 Suzuki DS80 1998 GN125 1996-1997 Yamaha AG100 2003-2010 2013 AG125 2017-2021 TTR125 LWE BIG WHEEL 2005-2008
