I think RK or Rikken were one of the suppliers to Honda Ken, i seem to remember different part numbers in the book for different suppliers
I don't think you will go wrong with genuine Riken rings Ken. Same with ART pistons. Not sure that Cruzin are the same quality as the genuine Riken items. Having said this, Yamiya sell 750 Riken rings a way lot cheaper than CMS and don't badge them as Honda. I just wish Yamiya would start selling 500/550 parts.

Reckons they are really soft metal in comparison to the Honda rings. I wish Yamiya would as well Ash.
