No copyright on marking rings ..you can stamp what like on them. I have Honda CB250K rings from the far east in red Honda packing with the Riken marks on them but they are definitely copies. Buyer beware, spoiling the ship ...blah blah blah. I would go for Genuine, Riken or NPR from a reputable source.

Do you have a reputable source Ash? Could do with sending them a piston so they can match them up.

Not really ..they seem really rare NOS and hence very expensive. I have no experience with IMD but perhaps someone on here has, and if they are good quality then worth a try. I notice originals are one piece oil control rings. Perhaps there is a later bike which may fit uses 3 -piece or IMD would probably supply 3-piece. (e.g one model CB125 single rings fit a CB500/4)

Ash,
I had a set off them for the Z650 about 2yrs ago and all seems well at the moment.
Not the cheapest but seem good quality.

IMD don't list them . I think C90 is 47mm bore size though or possibly C70 or both. Hairygit will know. I may have some sort of Honda 90 rings at home ..will check tonight.
Hmm think C90 may be 50mm bore ...ST70 is 47mm though.....Hairy ?????
