Hi Gary,
I had a Honda 250 Dream - but a bit unique as it was one of the first 6 Honda Dreams [250c to come into the UK. I was "breathed on" by Bill Smith who won a couple of TTs, and was faster than a few 500cc motor bikes, and could touch 115 mph. It was quicker than my Triumph T100 which could reach a touch over 100 mph.
Joking a bit about the IOM mountains -- I would love to take my S Type [208 bhp] over them. The big diesel loves the hills, and proved it last weekend in the Lake District. The only problem I have is that my wife thinks that at 81 I am too old for speed!
Regards,
Peter.
