RK’s 520EXW XW-Ring Chain is the simple, fool proof answer to your motorcycle or ATV chain questions. The 520EXW’s metal components are made from a specialized high carbon steel alloy that is shot peened, heat treated, and pre-stretched to create a chain that lasts for an incredibly long time. So tough in fact that it will outlast other 520 chains by 10%.

Another factor that makes the EXW such a long wearing chain is the unique design of the XW-Ring which closes off the chain rollers with an additional sealing surface that helps retain more lubricant compared to traditional O-ring seals. Not only will it last long, but with an 8,500 pound tensile strength, RK has made this chain strong enough for any off-road application with a 750cc displacement or less.
When you need a chain that is packed with features to keep it going mile after mile, snag the RK 520EXW XW-Ring Chain for a no-nonsense performer.
