A quality O-Ring chain at an affordable price for street and dual-purpose bikes. The SRO5/SRO6 chain is also suitable for ATVs.
The SRO series chains offer a value-priced O-ring chain that will not compromise on quality or durability.

420 and 428 chains come standard with SKJ clip-type (semi-press fit) connecting links which are 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 motocrosses, off-road, ATV, and drag racing chains. Can be easily installed with a pair of pliers.
