Vincent Black Shadow.
Just reading a bit about this bike, most would have seen the photo of no ATGATT!
Some may not know how it came about.
I think the guys name was Rollie Free? He was the big cigar smoking character in the Fastest Indian movie.
Apparently reaching 150mph was the magic speed to try and get but his first run with leathers flapping only got him to 147mph.
He then stripped down to his togs and got to 151.3 mph.
Imagine laying prone in your speedos doing that speed! With your slippers on.
