EK 630SRO O-Ring Transmission Chain 630 (Manufacturer part number: 630SRO-STL 84 MLJ) — a road chain designed for riders seeking robustness and longevity without complication. Part of the SRO series, it combines O-Ring seals and lightweight perforated construction to limit mass while maintaining the precision of EK CHAIN assemblies.
The O-Ring seals protect contact surfaces and help preserve the internal lubrication of the links for optimized maintenance intervals. The perforated design reduces unsprung mass, beneficial for the agility of roadsters without compromising the mechanical integrity provided by the heat treatment of the components.
Practical tip: check the 630 pitch and the number of links required for your setup before installation. Common compatibilities: Kawasaki GPZ 1100, Suzuki GS 1100 ES, Honda CB 750 K Four — see manufacturer references for adjustments.
