EK CHAIN 630SRO O-Ring transmission chain, manufacturer reference 630SRO-STL 100 MLJ. Designed for roadsters and street machines, this 630 with a standard pitch is intended for motorcycles requiring durability and low maintenance thanks to the O-rings.

The SRO series offers an interesting performance-to-price ratio: the links benefit from thermally treated steel alloys and controlled perforation to lighten the chain without compromising strength. The O-Ring seals trap lubricant between the rollers and pins, reducing wear and facilitating regular maintenance.
