EK Chains - SRO Series General Purpose O-Ring 530 Pitch

A quality O-Ring chain at an affordable price for street and dual purpose bikes. The SRO5/SRO6 chain is also suitable for ATV's.

The SRO series chains offer a value-priced O-ring chain that will not compromise on quality or durability.

Features include: lightening holes* (except for the 420SRO and the 428SRO), high-tech heat-treated steel alloys and all the exact same quality and craftmanship that EK puts into their entire product line.

420 and 428 chains come standard with SKJ clip-type (semi-press fit) connecting links which is easy to install and very similar to a standard SPJ link. The SKJ's re-designed link plate requires additional pressure to push onto the connecting pins but offers increased dependability and a tighter fit. Comes standard with many motocross, off-road, ATV and drag racing chains. Can be easily installed with a pair of pliers.

520 upward chains come complete with the MLJ (rivet-type) connecting link which is EK Chain's most dependable connecting link and more commonly used on street machines. Requires special riveting tool to install.

Different optional connecting links are available.

Also available (limited edition), in the SRO6 range, are the 520 chains, 120 links long, in black, red and orange.
