I raced a couple of years for Yamaha Pitmans in the 80's and Malcolm Pitman built my TT's with a YZ front end and wheels and White Power shock plus he built Kevin Long's TT's as well but he had White Power USD Forks on his TT which he won The News 24 Hour a couple of times. They weren't to bad of an Enduro bike but an excellent mustering bike. My dad had 4 of them until the TTR250 came out,
