That's correct, it was offered by CJ Ball Honda in Norwich, as the owner wanted to exchange it against the new CB1100. He kept the 1100 for around three years, however a sports injury meant that it became too heavy for him.
For a while, he had both the 750 and the 1100 together, but a lack of garage space meant that it was a temporary situation only. He has never lost the urge to own a CB750 though and occasionally rides my K2 and, at the end of every ride when he drops it off talks of swapping his Z900 RS for it!
