Renthal 525 R4 SRS Road Chain 130 Links C391

A chain is only as good as its ability to stay lubricated and sealed against the elements—and the Renthal 525 R4 SRS achieves this through intelligent engineering rather than brute force. The Self Regulating Seal technology adapts to wear over time, maintaining consistent performance throughout the chain's lifespan while reducing maintenance intervals. For sportbike and street motorcycle applications up to 1,300 cc, this is the chain that delivers reliability without compromise.

Built from high-alloy steel with shot-peened side plates, the R4 SRS combines tensile strength with flexibility that rivals or exceeds O-ring chains while offering smoother operation. The pre-stretched design means less fiddling during installation and break-in, letting you focus on what matters: riding. Whether you're pushing lap times or logging street miles, this chain handles the demands of modern high-powered motorcycles with precision and durability.
