Renthal R3-3 520 MX SRS Motorcycle Chain

Renthal R3-3 Off-Road Chain boasts a unique Self-Regulating Seal (SRS) design that are pre-loaded during assembly. The spring effect created during this process delivers constant seal pressure as the chain wears, allowing for extended lubrication intervals while delivering incredible durability unlike traditional O Ring chains which lose sealing pressure as they wear. The result is a strong, long-lasting, high-performance o ring dirt bike chain, ideal for extreme offroad & enduro applications. The R3-3 SRS chain utilises the same high performance materials found in the Renthal R1 Works MX Chain.
