anyone can fit on a nsr well mabe not I struggled to fit on a 28, it was like a bit of origami folding me on but I got there in the end. I am 6ft7 and 0ver 200lbs and I have been round knockhill and cadwell and the tt course on proddy 250s a a good pace so size dont matter.a 250tt will still give people a fright in the right hands, and if yours dont fit right you will learn.
