I checked into the Integra last summer when I was considering a Burgman. I even called Honda USA and asked them if they were considering importing it. A vague answer was given, of course, but at least a hint that it was under consideration. With the Honda SilverWing being VERY long in the tooth, something needs to be done to the Honda scooter stable at the top end.
For the current time, however, I did find from the NC700D Integra forum that there are owners in Canada! I don't know how difficult it would be to cross over the border, buy one, then import to America. But, it might well be worth all the trouble.
