This may have been covered before but after watching Mr. Shwantz and his fellow heros wrestling with their 170bhp 500cc 2 strokes, to me it has to be a Factory RGV500. I know I’d be terrified of it but that would be the one for me - just once!
For me the race bikes are a unrealistic proposition unless you're used to that sort of thing inlife,so i would like to try a RC30,i did swing my leg over one back in 1989 when the guy was at work...as you do.
Vincent Black Shadow for 1 day, I need an enterprising person to hire me 1 lol. Found one https://fatllama.com/rentals/potters-bar/hire-vincent-motorcycles-vincent-black-shadow-1952-84951718 Along the lines of an experience day. @Exige could do it with his collection of rides lol
There was a lad bought 1 lives near me, only saw it once on the road but he was going the other way. Think he had a few exotic bikes but that was a stand out in it’s day
Rob this isn’t in the spirit of the question you’re being greedy, but yes the Britten was the first bike to spring to my mind but then I thought a Vincent.
