Renthal RR4 SRS Gold 520 race chain
RENTHAL RR4 SRS Road Race Chain 120 Links Gold. For superbike & supersport high level race applications.
A highly specialized lightweight 520 sealed ring chain developed exclusively for racing applications where a combination of lightweight and durability are a must. Utilizes Renthal’s Self Regulating Seal (SRS) technology to increase service life. The specially developed SRS ring is preloaded during assembly creating 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 offers increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out.
