Nice photo.
Well, there must have been at least 4 early cb750s in England.
I have the Feb 71 Issue of Motorcycle mechanics, with a proud "Ooooo you are Awful, but I like you" Dick Emery on his first model candy blue/green CB750 ( Note: Finned oil cover, "450" Taillight assembly...as correct for UK), in living colour on the cover.
If I knew how to post it I would?
His number plate is "BYU762H"
I wonder if its still alive??
Of course there were the 2 English early CB750 test bikes...both "Red"
going by the B&W photos....."AYO61H" and restoed in the '80s "YLY70H" (finned oil covers, 450 taillight etc)
