Manufacturer reference: 420SRO-STL 108 SKJ — Brand: EK CHAIN
The EK 420SRO O-Ring 420 chain is a reliable and compact transmission designed for small displacement engines and applications requiring a 420 pitch. Made with heat-treated steel alloys and O-rings, it combines strength with protection against dust and debris. The perforation of the plates reduces weight without compromising the geometry of the links, ensuring neutral behavior during RPM changes.
Versatile, this chain is suitable for urban, cross, and roadster environments. It is perfectly suited for small motorcycles and mini-motorcycles listed as examples (Honda CRF 110 F, Yamaha YZ 85 LW Big Wheels, Gas Gas MC 65) or any machine requiring a 420 pitch and 108 links. To get the best performance from your transmission, adhere to the manufacturer's recommended maintenance intervals and tension.
