Magee won his first Grand Prix at the 1988 Spanish motorcycle Grand Prix at Jarama and the future looked bright for the young rider. However, at the 1989 United States motorcycle Grand Prix, he was involved in a terrible crash with Bubba Shobert on the cool off lap after the race, wherein Shobert drove into the back of Magee's motorcycle. Magee stopped his motorcycle in the middle of the track and performed a rear-wheel "burnout", presumably due to frustration that dwindling fuel had cost him 3rd place in the race. The wreck occurred while Shobert was congratulating racer Eddie Lawson and it ended Shobert's career. Ironically, Magee would crash at the same spot during the 1990 race, suffering head injuries that put him out for the season. In 1991 he appeared a couple of times for Suzuki and once for Team Roberts, along with another wildcard Grand Prix appearance in 1993.
