Designed for small displacement bikes and cross/urban/roadster practices, the EK 420SRO offers an accessible solution with O-Ring seals to limit lubrication loss between the links. This chain embodies EK's expertise: carefully designed perforations to lighten the connection, thermally treated steel alloys, and precision machining on each link.

• Type: 420 O-Ring chain
• Number of links: 100
• Color: Steel / Steel
• Weight: 0.78 kg (for 100 links)
• Relative lifespan: 1000 (manufacturer reference for 100 links)

Suitable for lightweight and mini-cross motorcycles (e.g., HONDA CRF 110 F JE02, YAMAHA YZ 85 LW CB10, GAS GAS MC 65), this 420 chain fits on sprocket/crown of the same pitch. Always check the number of links and tension after installation, and perform a gradual break-in to ensure proper seating.

For riders looking for a robust and economical chain with O-Rings, the EK 420SRO remains a reliable option to keep the drivetrain clean and lubricated for daily use as well as trail riding.
