Michael "Mick" Sydney Doohan AM born June 4, 1965 (1965-06-04) (age 42) in Brisbane, Australia, is a former Grand Prix motorcycle road racing World Champion, who won five consecutive 500 cc World Championships, second only to Giacomo Agostini (though Doohan's feat was basically equaled by Valentino Rossi, who won the final 500 cc GP championship, and the following 4 MotoGP championships, as MotoGP replaced 500 cc GP as the top championship on the world scene). He is considered to be one of the best motorcycle racers in the history of the sport.
Originally from the Gold Coast, near Brisbane, Doohan raced in Australian Superbikes in the late 80s, and also won both races as Superbike World Championship visited Oran Park in 1988. He is one of the few 500 cc or MotoGP World Champions to have won a Superbike World Championship race.
He made his Grand Prix debut for Honda on a 500cc two-stroke motorcycle in 1989. In 1991, he was paired with Wayne Gardner on a Honda RVF750 superbike and won the Suzuka 8 Hours endurance race. Doohan competed successfully throughout the early 1990s and appeared to be on his way to winning his first world championship when he was seriously injured in a practice crash before the 1992 Dutch TT. He suffered permanent serious damage to his right leg due to medical complications and, at one stage, risked amputation of the leg. At the time, Doohan was 65 points in the lead of the championship, but could not compete for eight weeks after the crash. After an arduous recovery, Doohan returned to racing for the final two races but could not prevent Yamaha rider Wayne Rainey from winning his third consecutive title.
