Who makes a 428 O-ring chain?

[snb73]

My son's KX-100 is in need of a new chain and sprockets. The bike had a DID 428, but I seem to be adjusting it before each ride. Does anyone make a 428 O-ring chain? I've been searching, but haven't found anything.

Thanks, Steve.

RK Chains has a 428 O-ring chain. We use it for offroad racing.

O-RING and X-RING much better for enduro, I think
