Moto cross history

Motocross first evolved in the United Kingdom from motorcycle trials competitions, such as hearing first quarter Auto-Cycle Club in 1906 and the Scottish Six Day of Judgment that began in 1909. When balancing smooth and tight score trials were eliminated by supporting the race to become the fastest driver to finish, it was called scrambles, said to have originated in the sentence, "the old scramble rare" describes one such early races. Originally known as scrambles racing in the UK, as the sport grew in popularity, the competition became known internationally as motocross racing, by combining the French word for motorcycles, motocyclette, or motto for the short term, be portmanteau with "cross country". The first known scramble race took place at Camberley, Surrey in 1924. 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 events. Off-road bikes from that era differed little from those used on the road. Intense competition in the rugged terrain brought technical improvements in motorcycles. Rigid frames gave way to suspensions by the early 1930s, and swinging fork rear suspension appeared by the early 1950s, several years before it was established in the majority of production street bikes. The period after the Second World War was dominated by BSA which had become the largest motorcycle company in the world. BSA riders dominated international competitions throughout the 1940s.

Motocross was introduced to the United States in 1966 when the Swedish champions, Torsten Hallman rose an exhibition event against the top American rider TT in Corriganville Movie Ranch also known as Hopetown in Simi Valley, California. The following year Hallman joined by other motocross stars including Roger Decoster, Joel Robert, and Dave Bickers. They dominated events lightweight two-stroke put them into sixth place finish. Motocross started to grow in popularity in the United States during this period, which fueled an explosive growth in the sport.

The air-cooled, twin-shock rear suspension typical two-stroke engines gave way to a water-cooled engine and equipped with a single-shock rear suspension absorber. In 2003, environmental laws are more stringent in California forced some manufacturers to develop a four-stroke technology is environmentally friendly. In 2004, all the major manufacturers have begun competing with four-stroke engines. European firms also experienced a resurgence with Husqvarna, Husaberg and KTM winning world championships with four-stroke engines.

Sport evolved with sub-disciplines such as stadium events known as supercross and arenacross held in the indoor arena. Classes are also created for all-terrain vehicles.
