Imagine a 750 Two stroke four in a flat track frame and you have a Steve Baker replica flat tracker. They raced these for one race but the AMA banned them probably due to Harley Davidson crying about the butt kicking they experienced. You should read or find a video about Kenny Roberts exploits on the TZ750 at the Indianapolis mile. This is a beautiful TZ750 flat tracker and it is street legal. I love the sound of that two stroke with the four expansion chambers. The TZ750 was a dominant force in American Road Racing and Steve Baker actually won a Formula 750 World Championship on a TZ750
Remember if it don't smoke its broke!!!
