The titular event, Isle of Man TT Race (known as Isle of Man TT Festival from 1989 onwards) is one of the most prestigious motorcycle circuits, taking place annually from 1907 on the Isle of Man, a self-governing dependency between Ireland and Great Britain. Between 1949 and 1976 the event was a part of FIM Motor-cycle Grand Prix World Championship, known as the World Series of motorcycle racing. As a result of the controversies regarding the safety of the event, the Isle of Man series had been removed from the championship schedule, retaining its fame as one of the most dangerous cyclical sport events that is notorious for taking the lives of 251 participants throughout its duration.
