AMA Supercross is one of the highest-profile motorsports in the world. It features world-class athletes pushing motorcycles to their limits in stadium settings across the country.
It all begin in 1971 when the AMA conducted a professional motocross race on a temporary track at Daytona International Speedway. While most motocross races had been held in the remote, rural countryside, Daytona brought motocross to the people. A year later, the concept was taken a step further — motocross was brought to major urban sports stadiums, beginning with the Los Angeles Coliseum. The term “Supercross,” a combination of Super Bowl and Motocross, was coined. In the 1980s and 1990s, teams, motorcycle manufacturers, broadcast partners, race facilities and sponsors worked together to bring the sport to new audiences. Top Supercross riders became household names, and off-road motorcycle sales soared.
Today, AMA Supercross is undisputedly the top Supercross series in the world and draws elite rider talent from every corner of the globe. An international cadre of manufacturers targets their best equipment and development teams at these series in the quest for Championship titles.
The AMA Supercross Championship is presented in the 450 SX class, which primarily features four-stroke 450cc technology. The 250 SX class, which showcases riders on four-stroke 250cc motorcycles, is split into U.S. eastern and western regional divisions, each awarding its own title.
