420 MX - Drive Chain - 130 Link

DRIVE CHAINSProX has developed a premium line of Roller Chains to team up together with the ProX front and rear sprockets. The ProX Roller Chain is a top quality chain, exclusively manufactured for ProX by the reputable and leading OEM factory in Japan. All ProX chains are made using highest grade Japanese steel. The MX chains are assembled out of various different components that all have their specific and crucial function to make the chain a high quality product. Pins do feature an exclusive pin treatment providing an extremely hard outside coating, leaving a softer inside to increase strength while reducing overall chain wear. The pins are heavy press fitted and do feature quad staked riveting for ultra-strong connection. The solid bush inside the shot-peened, solid roller and plates are all heat treated to offer an incredible tensile strength in combination with low friction and high wear resistance. Inner plates are designed in a specific shape allowing less material to be used which in combination with the unique lightning holes results in a 3% overall lighter chain without compromising tensile strength. Specifically for the Off-road, Enduro, ATV and big 4-Stroke Motocross bikes ProX also offers a lightweight, narrow type X-Ring chain using a QX-type seal offering 40% less friction and at least 150% increased durability over a standard MX Chain. All ProX chains are pre-stressed and pre-stretched to reduce initial chain stretch and immediate performance and come with a clip type chain link as standard.
