Harvey Mushman was the alias of king of cool, Steve McQueen. Used to avoid undue attention from movie studios who tried to ban him from racing.
Steve McQueen participated in lots of off-road races including the Baja 1000, the Mint 400 & the Elsinore Grand Prix.
In 1964, on his Triumph TR6 Trophy, he represented the US in the International Six Days Trial (ISDT), a form of off-road motorcycling Olympics. McQueen's now famous ISDT competition number was 278, which was based on the trials starting order.
MAX MUMBLES says: "Steve McQueen an actor who raced or a racer who acted?"
