A Friend of mine, Billy Broad used to Flat Track when it was big around our parts.
He used to have it rebuilt every year by a guy in Texas. One day, he put the Triumph thru
a chain link fence on a curve, at a very high speed. He has a long scar down his one shin to prove it.
I had a single cylinder Bultaco Flat Tracker. Single cylinder and it had almost the same hp as a 750 Honda 4 cylinder. So wasn't difficult to crack it in a corner and hot foot it.
