RENTHAL RR4 RACING Chain - 520 x 120 links
Developed exclusively for racing applications.
Renthal’s RR4 A highly specialized lightweight 520 sealed ring chain developed exclusively for Superbike racing applications where a combination of light weight and durability are a must. Utilizes Renthal’s Self Regulating Seal (SRS) technology to increase service life. The specially developed Self Regulating Seal (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.
All road race chains come in 120 links only to allow for your choice of gearing.
