Robert William Hannah (born September 26, 1956) is an American former professional motocross racer.
He competed in the AMA Motocross Championships from 1976 to 1989, most notably as a member of the Yamaha factory racing team.
He was one of the most successful motocross racers in AMA history, with 70 AMA national championship race victories and 7 motocross national championships.Hannah was a brash and outspoken personality whose wild riding style, seemingly on the verge of losing control and often with his feet off the foot pegs, earned him the nickname, "Hurricane Hannah".
His physical fitness, fierce determination on the race track and a hatred of losing, reshaped American motocross by boosting the speed and competition to higher levels.
He was at the forefront of a surge in American motocross competition in the late 1970s and early 1980s that saw American riders overtake and surpass the previously dominant European motocross riders.
Hannah was inducted into the AMA Motorcycle Hall of Fame in 1999 and the Motorsports Hall of Fame of America in 2000.
