Motocross Racing Bikes Wallpapers And News

                           Motocross first evolved in the United Kingdom from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1906 and the Scottish Six Days Trial that began in 1909. When delicate balancing and strict scoring of trials were dispensed with in favour of a race to be the fastest rider to the finish, it was called scrambles, said to have originated in the phrase, "a rare old scramble" describing one such early race. Originally known as scrambles racing in the United Kingdom, as the sport grew in popularity, the competitions became known internationally as motocross racing, by combining the French word for motorcycle, motocyclette, or moto for short, into a 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 the events. Off-road bikes from that era differed little from those used on the street. The intense competition over rugged terrain led to 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 incorporated on the majority of production street bikes. The period after World War II was dominated by BSA which had become the largest motorcycle company in the world. BSA riders dominated international competitions throughout the 1940s.

                                  As the competition intensified and the terrain increased in difficulty, the technology used for the design of competition and special-event motorcycles would improve, particularly with the introduction of the swinging arm suspension during the early 1950s. The international motorcycling governing body held the 500cc displacement formula European Championship in 1952 that was subsequently upgraded to World Championship status in 1957 followed by a 250cc equivalent in 1962 where two-stroke motorcycles began to make their mark in the industry.

                               Various companies throughout Europe from countries such as Sweden, Czechoslovakia and Britain thrived by creating models that became renowned for their lightness and maneuverability. The introduced improvements in motorcycles during the 1960s would relegate the older and heavier four-stroke machines to smaller, niche events.

                                It was during the 1980s that rapid technological enhancements in motocross would take place thanks to the innovation of companies from Japan. These included the creation of water-cooled machines as well as the monoshock rear suspension device. During the 1990s, new laws were introduced to ensure that the production of four-stroke motorcycles would adhere to environmentally conscious standards.

                                   Motocross racing is one of the most visually appealing forms of motorsport, with riders performing seemingly death-defying leaps, turns visibly at the edge of traction (as indicated by a sliding, spinning rear tyre throwing dirt at all behind it), and the effort of riders clearly visible as the move their bodies around their motorcycles to balance the bikes for maximum speed. Capitalising on this appeal, two variants called supercross and arenacross have evolved, held on tighter tracks in sports stadiums (even indoors) with more, even higher jumps. Freestyle motocross, a relatively new sport, shuns racing and concentrates on performing acrobatic stunts while jumping these motorcycles.
