Renthal RR4 SRS Z-Ring Road Race Drive Chains

Renthal RR4 SRS Z-ring road race drive chains are super chains for Superbikes! They are highly specialized lightweight 520 sealed ring road race chains that utilize Renthal's Self Regulating Seal (SRS) technology to increase service life. The SRS Z-ring is preloaded during assembly, creating a spring effect. Then, unlike conventional O-rings, the self-regulating ring chains have the ability to unload themselves during use, keeping a tighter seal against the side plates and increasing the longevity of the chains, because the grease stays in and the dirt and water stays out. When light weight and durability are an absolute must, your chain of choice should be Renthal RR4 SRS Z-ring road race drive chains. RR4 SRS Z-ring chains' other features and benefits include: * High-alloy steel plates and pins * Solid bushings and rollers * Shot-peened side plates for added strength * Pre-stretched, so less adjustment needed during initial break-in * Includes latex gloves for mess-free install Show Less
