History

Motocross evolved in the UK out of trials, such as the Auto-Cycle Clubs's first quarterly trial in 1906 and the Scottish Six Days Trial that began in 1909.[1] When delicate balancing and strict scoring of trials were dispensed with in favor of a flat out 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.[1] When scrambles spread to the European continent, the French word for motorcycle, motocyclette, or moto for short, was combined in a portmanteau with "cross country", and the name motocross stuck.[1] The first known scramble took place at Camberley, Surrey in 1924.[2] 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.[3] The period after the Second World War was dominated by BSA which had become the largest motorcycle company in the world.[3] BSA riders dominated international competitions throughout the 1940s.[3]

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 it to World Championship status.[3] In 1962, a 250 cc world championship was created.[3] It was in the smaller 250 cc category that companies with two-stroke motorcycles came into their own. Companies such as Husqvarna from Sweden, CZ from the former Czechoslovakia and Greeves from England, became popular due to their lightness and agility.[3] By the 1960s, advancements in two-stroke engine technology meant that the heavier, four-stroke machines were relegated to niche competitions. Riders from Belgium and Sweden began to dominate the sport during this period.[citation needed]

Motocross was introduced to the United States in 1966 when Swedish champion, Torsten Hallman rode an exhibition event against the top American TT riders at the Corriganville Movie Ranch also known as Hopetown in Simi Valley, California. The following year Hallman was joined by other motocross stars including Roger DeCoster, Joël Robert, and Dave Bickers. They dominated the event placing their light weight two-strokes into the top six finishing positions.[4][5]

By the late 1960s, Japanese motorcycle companies began challenging the European factories for supremacy in the motocross world. Suzuki claimed the first world championship for a Japanese factory when Joël Robert won the 1970 250 cc crown.[6] Motocross also began to grow in popularity in the United States during this period, which fueled an explosive growth in the sport. The first stadium motocross event was held in 1972 at the Los Angeles Coliseum.[7] In 1975, a 125 cc world championship was introduced.[8] European riders continued to dominate motocross throughout the 1970s but, by the 1980s, American riders had caught up and began winning international competitions.[9]

During the early 1980s, Japanese factories presided over a technology boom in motocross. The typical two-stroke air-cooled, twin-shock rear suspension machines gave way to machines that were water-cooled and fitted with single-shock absorber rear suspension. By the 1990s, increasingly stringent environmental laws in California forced manufacturers to develop environmentally friendly four-stroke technology.[10][11] At the turn of the century, all the major manufacturers have begun competing with four-stroke machines. European firms also experienced a resurgence with Husqvarna, Husaberg and KTM winning world championships with four-stroke machinery.

The sport evolved with sub-disciplines such as stadium events known as supercross and arenacross held in indoor arenas. Freestyle motocross (FMX) events where riders are judged on their jumping and aerial acrobatic skills have gained popularity, as well as supermoto, where motocross machines race on both tarmac and off road. Vintage motocross events have also become popular with riders competing on bikes usually pre-dating the 1975 model year.[citation needed]

The world is dominated by two main Motocross series; the FIM's Grand Prix, the World Championship series, and the AMA's American National Championship. The AMA Motocross champions in 2010 were 250 - Trey Canard (USA), Christophe Pourcel(FRA) and Dean Wilson (GBR) 450 - Ryan Dungey (USA), Brett Metcalfe (AUS) and Andrew Short (USA)

The Grand Prix (or Motocross World Championship) is predominantly held in Europe with some "flyaway" rounds, recently in Chile, South Africa, Japan and the United States, but over its history it has visited numerous countries including; Indonesia, Australia and countries on both American continents. There are three classes: MX1, MX2 and MX3 (analogous to "450cc" and "250cc", and "open", respectively). Race day consists of two moto's with a duration of 35 minutes plus two laps, while the series is longer, generally incorporating over 16 rounds.

The AMA Motocross Championship (the "outdoor series") season begins in early May and continues until mid-September, and consists of twelve rounds at twelve major tracks all over the continental United States. There are two classes:[12] the 250 Motocross Class for 0–125 cc 2-stroke or 150–250 cc 4-stroke machines; and the 450 Motocross Class for 150–250 cc 2-stroke or 251–450 cc 4-stroke machines.

The annual Motocross des Nations (now called Motocross of Nations) is usually held at the end of the year when National and World Championship series have ended. The format involves teams of three riders representing their nations. Each rider competes in a different class (MX1, MX2 and "Open"). There are three motos with two classes competing per moto. The location of the event changes from year to year. The United States, Belgium and Great Britain have had the greatest success.

The Maxxis British Motocross Championship is the main UK off road competition and organised into classes of MX1 and MX2. MX1 for is for 251cc to 450cc (fourstroke) and MX2 for 175cc to 250cc fourstroke motorcycles.[13] In 2007 an additional youth class, the MXY2 class, was added to the programme at selected rounds.[14]

A 'Veterans' series was introduced in 2009 with just two rounds but the demand for places was so high that from 2011 the Veterans series will have three rounds, held over six races.[15]
