Motocross was first evolved in the U.K. from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. During the 1930s, the sport grew in popularity, especially in Britain where teams from the Birmingham Small Arms Company (BSA), Norton, Matchless, Rudge, and AJS competed in the events. In 1952, the FIM, motorcycling's international governing body, created an individual European Championship using a 500 cc engine displacement formula. In 1957 it was upgraded to World Championship status. During the late 1970s and early 1980s, Japanese motorcycle manufacturers presided over a boom period in motocross technology. The sport evolved with sub-disciplines such as stadium events known as supercross and arenacross held in indoor arenas.
