History of Motocross

In 1924, the first known British off-road event known as the Scrambles was held at Camberley in Surrey. This would become the earliest known origin of freestyle motocross as we know it today.

Over the years, the event would evolve, largely through the efforts of riders from Europe who shortened the tracks while adding laps and various obstacles through the course such as jumps.

The sport's popularity would increase during the 1930s, particularly in Britain where events involving teams from various districts and companies would be held regularly. Bikes used in those competitions at the time would be barely distinguishable from those used on the streets.

1950s to 1970s

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 machines.

In the late 1960s,

companies from Japan would rival their European counterparts in the manufacture and production of high-quality motorcycles for motocross enthusiasts. In fact, in 1970, Suzuki would claim the first world championship for its motherland after being victorious in the 250cc event.

1975 would see the introduction of the 125cc world championship and the sport experienced significant growth due in no small part to the increase in popularity of motocross in the United States. While European riders would continue to excel in events held during the 1970s, the Americans would gradually improve before winning international competitions during the 1980s.

1980s to 1990s

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 Today

Recently, motocross has gradually developed new forms of riding and disciplines ranging from indoor stadium arena events such as Supercross and Arenacross to Freestyle Motocross where riders display an array of skills while performing thrilling jumps and stunts.

FIM Motocross World Championship

The Grand Prix (or Motocross World Championship) is predominantly held in Europe with some "flyaway" rounds, recently in Chile, South Africa and Japan, 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.

AMA Motocross Championship


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; "125cc" and "250cc". Each round has two motos of thirty minute-plus-two-laps

Motocross des Nations

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.

Freestyle

Supermoto

Freestyle Motocross (FMX), a relatively new variation of supercross, does not involve racing and instead concentrates on performing acrobatic stunts while jumping motocross bikes. The winner is chosen by a group of judges. The riders are scored on style, level of trick difficulty, best use of the course, and frequently crowd reactions as well. FMX was introduced to the X Games and mainstream audiences in 1999.

Supermoto involves taking a motocross bike meant to be raced off-road and converting it to be raced on tracks consisting of both dirt and pavement. The bikes are fitted with special road racing tires and are "grooved" to grip both the pavement and dirt. Some tracks for these race events have jumps, berms, and whoops just like true

motocross tracks. For special events, the Supermoto track may incorporate metal ramps for jumps that can be disassembled and taken to other locations. Supermoto races may take place at modified go-kart tracks, road racing tracks, or even street racing tracks. There are also classes for kids such as the 85cc class.

ATV/Quad Motocross

Throughout the United States and the United Kingdom there are many quad racing clubs with enduro and quadcross sections. GNCC Racing began around 1980 and includes hare scramble and enduro type races. To date, events are mainly held in the eastern part of the United States. GNCC racing features many types of obstacles such as, hill climbing, creek and log crossings, dirt roads and wooded trails.

ATV National Motocross Championship] was formed

around 1985. ATVMX events are hosted at motocross racetracks throughout the United States. ATVMX consists of several groups, including the Pro (AMA Pro) and Amateur (ATVA) series. Championship mud racing (CMR) saw its infancy in 2006 as leaders of the ATV industry recognized a need for uniformity of classes and rules of various local mud bog events. Providing standardized rules created the need for a governing body that both racers and event

promoters could turn to and CMR was born. Once unified, a true points series was established and lead to a national championship for what was once nothing more than a hobby for most. In 2007 the finalized board of directors was established and the first races were held in 2008. Currently, the CMR schedule includes eight competition dates spanning from March to November. Points are awarded throughout the season in several different competition classes of ATV and SxS Mud Racing. The


2008 year included Mud Bog and Mudda-Cross competitions, but the 2009 and future seasons

will only have Mudda-Cross competitions. Classes range from 0–499 cc to a Super-Modified class which will

allow any size ATV in competition.

Supercross

Supercross is a cycle racing sport involving racing specialized high performance off-road motorcycles on artificially-made dirt tracks consisting of steep jumps and obstacles. Professional Supercross contest races are held almost exclusively within professional baseball and football stadiums. Many notable differences exist from regular motocross. Supercross tracks generally have much tighter turns and are more technical than motocross tracks due to the

limited space of an indoor arena. The supercross season takes place during the winter and spring months, partially due to more controllable indoor climates involved.

Travis Alan Pastrana

Travis Alan Pastrana (Born October 8, 1983, in Annapolis, Maryland) is a motorsports competitor and stunt performer who has won championships and X Games gold medals in several events, including supercross, motocross, freestyle motocross, and rally racing.

Motocross/Supercross

Pastrana has won two motocross racing championships, the 2000 A.M.A. 125cc National championship, and the 2001 125cc East Coast Supercross Championship. Pastrana also raced in the 2000 MX of Nations. Pastrana moved up to the 250cc class or "Supercross" class in 2002. Pastrana's stand-up style, ability to spot jump combinations and great speed through the whoops make him easy to spot on the track. Although Pastrana has never won a 250cc race, his kindness to the fans and love of the sport still makes him one of the most popular riders of all time. Pastrana has always raced and competed on Suzuki motorcycles, and remains fiercely loyal to the brand. He races with Team Cernic's Suzuki. His motorcycles and rally cars carry the number 199.
