The EK 630 SRO drive chain is a durable, value-focused replacement chain designed for powersports applications requiring dependable performance. Manufactured by EK Chain, this model uses high-tech heat-treated steel alloy construction to provide strength and durability under demanding riding conditions. The 110-link configuration supports fitment on select motorcycles, ATVs, and other compatible vehicles using a 630-size chain system.
O-ring seals help retain factory-applied lubricant inside the chain joints while helping prevent dirt, grit, and other contaminants from entering. This design supports consistent operation, reduced maintenance, and extended service life compared with standard non-sealed chain designs. Integrated lightening holes help reduce unnecessary chain weight while maintaining a practical balance of strength and performance.
Verify your vehicle manufacturer’s application requirements, chain size, sprocket compatibility, and required link count before installation. The EK 630 SRO is supplied as a 110-link drive chain and may require sizing or adjustment for the specific application. Manufacturer part number 630SRO-110 and vendor part number 630SRO-110 identify this EK replacement chain.
