Classic racing .Its a tough call , at some of the BHR meetings I have been doing there are modern day copies running in a classic race. But these are not just copies they are upto date modern day technology copies, they are so much bettter that the bikes they are supposed to a copy of. But then how much of a bike can you change for modern day engineered copy bits and it still remains classic ?

I know with the classic TT there were bikes using out of era engines and parts which is just against the grain .

But where and who draws the line in the sand ?
