Hi, I have just bought a 1970's Suzuki GT550 off the dreaded e-bay! and wanted to trace a bit of history. It was raced in the Isle of Man and has SMGP RACING on the tank and the racing no 6 on the front, it has box section swinging arm/expansion pipes/rear sets etc which i think are Dunstall items? I wondered if anyone knows anything about it or SMGP racing? Cheers, Tim.
