This model Honda was never exported to the United States market, but many were sold in other markets, especially Japan. It appears a few were sold in Canada, accounting for all the ones of which I'm aware within our borders as I write this. There were larger "Dream" versions of this upswept exhaust twin sold in the NorAmer markets however, know as the CS(A)71, CS(A)76 250cc Dry Sumps, and the CS(A)72 & CS(A)77 305cc Wet-Sumps.
