EK 420SRO O-Ring Drive Chain — Manufacturer part number: 420SRO-STL 130 SKJ. Part of EK CHAIN's SRO series, this O-Ring chain offers an economical solution for small displacement motorcycles without compromising on meticulous manufacturing processes. Designed with thermally treated steel alloys and perforated links to reduce weight, it maintains the precision characteristics that the brand is known for.

• Type: O-Ring drive chain

For maintenance: check the tension, inspect the condition of the O-Rings, and lubricate regularly to maximize the chain's longevity.
