Thank you so much for the outstanding photos!
The two neatest bikes in your pics for me are the black CS92 (or it could be a CS95) with the high pipes - "S" standing for "Sport" if you can believe it and the red CB450 with factory-installed left and right side high pipes - not both on the left like the CL450. I've got photos of both in old magazines but never ever saw either one here in Canada.
Some of the other bikes might be what today we'd call grey market bikes - they were never imported into the States by Honda. A lot of servicemen brought them back after their tours of duty overseas ( mainly 'Nam but Europe as well).
When you're back there, have a look around for any 125cc twins with dual carbs and if you see any, I'd be obliged if you'd snap a few photos for me... 'cause they're really rare over here (I've only ever seen one).
Great find, great piccies, thanks for making my Monday!
