After racing motocross as a child, Russell raced in WERA events before reaching AMA in 1987. In 1988 he was runner-up in the 750 cc Supersport class and also had some successes in Superbike and 600 cc Supersport. He was Superbike runner-up in 1989, before winning the 750 cc Supersport title three years in a row from 1990 to 1992 and winning every race in 1991. In 1992, Russell claimed the AMA Superbike championship. In the 1995 Daytona 200 he crashed on the first lap, but got back on the bike and won, finishing ahead of Carl Fogarty. Having previously scored a handful of World Superbike podiums, he became the Superbike world champion riding for MuzzyKawasaki in 1993, and was runner-up in 1994. He left the series after a poor start to 1995, replacing the retired Kevin Schwantz at Suzuki in the 500 cc Grand Prixworld championship. Staying with Suzuki in 1996 he finished sixth overall. Russell returned to World Superbikes with Yamaha in 1997, coming sixth overall with a pole and two podiums. In 1998, he came tenth overall but rarely ran near the front. His season is most remembered for the Laguna Seca round, in which he made a blatant jump start and ignored the instruction to come in for a stop-go penalty, eventually falling off, almost causing teammate Noriyuki Haga to crash. Russell had an unsuccessful spell racing Harley-Davidson bikes in the AMA Superbike championship during the following two years. His final year in AMA Superbike ended at the first race of 2001 at Daytona after a move to the HMC Ducati team. Ducati had high hopes that "Mr. Daytona" would help them achieve their first ever 200 win. However, during the start, Russell's bike stalled and was hit from behind after trying to move out of the way to the side of the track. Russell suffered severe injuries which ultimately ended his two-wheeled career. In 2005, Russell was inducted into the AMA Motorcycle Hall of Fame. Scott returned to the highbanks of Daytona in 2008 on a Jamie James prepared Yamaha R1. Russell began serving as lead motorcycle road racing analyst for SPEED TV in May 2009, replacing Freddie Spencer whose European scheduling conflicts led to the change. In 2008, Russell made the switch professionally to four wheels, racing in the Grand American Road Racing Association in both the Rolex Sports Car Series and Koni Challenge series. In the 2010 season, he won Round 11 at Montreal along with co-driver Paul Edwards.
