EK 630SRO O-Ring Drive Chain 630 - Manufacturer Ref: 630SRO-STL 94 MLJ
Designed for demanding roadsters, the EK 630SRO chain incorporates EK CHAIN's expertise with a durable construction and a steel/steel finish. Equipped with O-rings, it minimizes oil loss between links and facilitates maintenance while protecting wear surfaces.
The SRO series focuses on thermally treated steel alloys and a carefully designed perforation to reduce weight without sacrificing strength. The result: a drive chain that withstands everyday demands — starts, accelerations, and long rides — while remaining easy to install and maintain.
Ideal for both vintage and modern roadsters, it is particularly suitable for models such as Kawasaki GPZ 1100, Suzuki GS 1100 ES, and Honda CB 750 K Four. For a clean and secure chain replacement, pair it with a quality sprocket and crown, and adhere to the recommended torque and installation guidelines.
