Renthal are a global player in the manufacture and distribution of motorcycle accessories. Their obsession for detail, quality and engineering, ensures everything from handle bars, grips, sprockets and chains make Renthal products one of the finest on the market today! For road and road race applications Renthal 's 'SRS' chain has been specially developed and features sealed ring chain which utilises Renthal's Self Regulating Seal (SRS) technology to help increase the service life of the drive chain. The special SRS ring is pre-loaded during assembly to create a spring effect. As the chain wears, conventional O-rings and X-rings lose their seal, however the SRS ring has the ability to 'unload' itself during use keeping a tighter seal against the side plates. This ensures increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area for longer, helping to keep dirt, water and other contaminants out. Chain types offered: R4 SRS: A premium high grade sportsbike specific z-ring chain, supplied in 520, 525 and 530 pitch options. RR4 SRS: A premium high grade 'road race' specific z-ring chain, supplied in 520 pitch.
