The R4-2 chain range incorporates Renthal's SRS (self-regulating seals) ring system, increasing chain longevity. In this system the seals are pre-loaded during assembly, creating a spring effect. SRS chains have the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain, retaining the vacuum injected grease inside the critical bush and pin wear areas. This equates to a 40% increase in chain life at no additional cost.
Note: Make sure to check your owner's manual for the proper application, especially if you are installing a O-ring chain on a bike that came from the factory with a non O-ring chain.
