EK 420SRO O-Ring Drive Chain — Manufacturer part number: 420SRO-STL 134 SKJ
The SRO series from EK CHAIN offers an accessible O-ring chain designed for riders who want a reliable part without extravagance. Built with a reduced perforation to limit weight and heat-treated steel alloys, this 420SRO retains EK's precision craftsmanship while being easy to maintain thanks to its O-Ring seals.
Suitable for Urban, Cross, and Roadster environments, this chain is designed for transmissions requiring a 420 pitch. It is ideal for standard replacements or restorations where simplicity, apparent robustness, and ease of maintenance (regular lubrication recommended) are desired.
