It’s the bike that inspired Kenny Roberts, one of the most fearless motorcycle racers that ever lived, to utter these immortal words: “They don’t pay me enough to ride that thing!” Desperate to compete with the dominant Harley-Davidson XR750s in the 1975 AMA Grand National championship, tuner Kel Carruthers shoe-horned the two-stroke four-cylinder from King Kenny’s TZ750 roadracer into a Champion flat track frame and set him loose at the 1975 Indy Mile. Roberts won that race from a near-last-place start, cementing his name forever in flat track history. The TZ750 flat tracker made 125 horsepower, had a light-switch powerband, a 150-plus mph top speed and no front brake. It was so fast, and so difficult to control, that the AMA banned it from competition after just three races—before someone got killed. Now the very same bike has been restored to riding condition, and Editor-in-Chief Catterson wants me to ride it for your entertainment. Is this his sick and twisted idea of an “early retirement” program, or what?
