Features

EK CHAIN 420SRO O-Ring 420 — Manufacturer Ref: 420SRO-STL 84 SKJ

Designed for small displacement bikes and light off-road use, the 420SRO from EK is an O-ring transmission chain that emphasizes durability and weight control. Its construction utilizes heat-treated steel alloys, combined with EK's precision craftsmanship, to provide a reliable chain suitable for urban, motocross, and roadster environments.

Type: O-Ring Chain
Pitch: 420
Number of Links: 84
Color: Steel / Steel
Weight: 0.78 kg / 100 links
Relative Lifespan: 1000 (based on 100 links)
Features: perforation for weight reduction, heat-treated steel

The presence of O-rings helps maintain lubrication between the links and limits dirt intrusion — an advantage on muddy paths as well as in urban settings. Ideal for small-sized motorcycles, this chain is particularly compatible with models listed by the manufacturer: HONDA CRF 110 F (2026), YAMAHA YZ 85 LW BIG WHEELS (2026), and GAS GAS MC 65 (2025).

For a clean and secure installation, check the number of links and pitch before installation. Chain sold according to manufacturer reference: 420SRO-STL 84 SKJ.
