EK 630SRO O-Ring transmission chain by EK CHAIN, designed for roadster machines that demand reliability and value for money. Coming from the SRO series, this O-Ring chain combines a lightweight design—through perforations on the links—with heat-treated steel alloys to maintain precision and longevity in the transmission.
The O-Rings help maintain internal lubrication between pins and bushings, limiting dirt intrusion and improving durability compared to a non-sealed chain. The perforated construction reduces mass while retaining the necessary mechanical strength for road use and typical roadster accelerations.
Compatible with classic large displacements such as the KAWASAKI GPZ 1100, SUZUKI GS 1100 ES, or the HONDA CB 750 K FOUR, this EK chain is aimed at riders looking for a reliable replacement for transmission maintenance. Installation and adjustment according to manufacturer recommendations are recommended.
