His dirt track-based riding style changed the way Grand Prix motorcycles were ridden. Roberts left his mark on Grand Prix motorcycle racing as a world championship winning rider, a safety advocate, a racing team owner, and as a motorcycle engine and chassis constructor. Roberts is one of only four riders in American Motorcyclist Association (AMA) racing history to win the AMA Grand Slam, representing Grand National wins at a mile, half-mile, short-track, TT Steeplechase and road race events. He was also a two-time winner of the A.M.A. In 1978, he became the first American to win a Grand Prix motorcycle racing world championship.
