History

Motocross first evolved in Britain from

competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When organisers dispensed with delicate balancing and strict scoring of trials in favour of a race to become the fastest rider to the finish, the activity became known as " hare scrambles", said to have originated in the phrase, "a rare old scramble" describing one such early race. Though known as scrambles racing (or just scrambles) in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, ''motocyclette'', or ''moto'' for short, into a

competitions. Off-road motorcycles 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 manufacturers incorporated it in 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. In 1952 the FIM, motorcycling's international governing body, set up an individual European Championship using a 500 cc engine displacement formula. In 1957 it was upgraded to World Championship status. In 1962 a 250 cc world championship was established. In the smaller 250 cc category companies with

, the FIM introduced a 125 cc world championship. European riders continued to dominate international motocross competitions throughout the 1970s with Belgian or Swedish riders winning ten Motocross des Nations (MXDN) events between 1969 and 1980 but, by the 1980s, American riders had caught up with American teams winning a string of 13 consecutive MXDN victories between 1981 and 1993. Brad Lackey became the first individual American motocross world champion in 1982 after an 11 year pursuit of the title. From the late 1970s to early 1990s, Japanese motorcycle manufacturers presided over a boom period in motocross technology. The typical air-cooled two-strokes with twin-shock rear suspension and telescopic front forks gave way to

engines and single-shock absorber rear suspension and "upside-down" (or inverted) front forks. Although the advancement of two-stroke engine technology was the primary focus of the major Japanese motorcycle manufacturers well into the mid 1990s, a rekindled interest in engineering a competitive, lightweight four-stroke motocross race bike was expressed among several brands, including Yamaha Motor Corporation and Husqvarna. Facing tightening federal emissions regulations in the United States, the AMA increased the allowable displacement capacity for

engines in 1997, in an effort to encourage manufacturers to develop environmentally friendlier four-stroke machines. Due to the low relative power output of a four-stroke engine compared to the then-dominating two-stroke design, the displacement limit of a four-stroke power motocross bike was raised to 250cc in the 125 class and 550cc in the 250 class. The new regulations resulted in competitors aboard four-strokes made by smaller European manufacturers, with Husqvarna,

AMA Motocross Championship

The AMA Motocross Championship begins in mid May and continues until late August. The championship consists of twelve rounds at twelve major tracks all over the continental United States. There are three classes: the 250cc Motocross Class for 150–250 cc 4-stroke machines, the 450cc Motocross Class for 251–450 cc 4-stroke machines and a 250cc Women's Class, using the same rules as men's 250cc. Race events take place over two motos of 30 minutes plus two laps each.

Motocross des Nations

The annual Motocross des Nations is held at the end of the year when National and World Championship series have ended. The competition 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.

British Motocross Championship

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

Sports derived from motocross

A number of other types of motorcycle sport have been derived from Motocross.

Supercross

Supercross is a cycle racing sport involving specialized high-performance off-road motorcycles on constructed dirt tracks with steep jumps and obstacles. Compared to regular motocross, supercross tracks generally have much shorter straights and tighter turns. Professional supercross races, held as the AMA Supercross Championship in the

, are held almost exclusively in professional baseball and football stadiums. The supercross season takes place during the winter and spring months, with races in a different city every weekend. There are 17 races in the AMA Supercross Championship schedule, normally beginning in Anaheim, California, and ending in Las Vegas, Nevada. The 250 cc class is split into two series, east and west. The 450 cc class has one large series with events across the US and Canada. In 2022, the World Supercross Championship was demerged from the AMA Supercross Championship, to be held as a standalone series once more. The series previously ran from 2003 to 2008. Supercross events are also held in

Freestyle

Freestyle Motocross (FMX), a relatively new variation of supercross started by the South African champion, Marco Urzi, does not involve racing and instead it 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. FMX was introduced to the X Games and mainstream audiences in 1999.

uses motocross bikes converted for racing on tracks consisting of three sections: flat dirt, dirt obstacles, and paved road. The bikes have special road-racing tires with grooved tread to grip both the pavement and dirt. Some tracks for these race events have jumps, berms, and whoops like 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 children, such as the 85 cc class. Supermoto began in the US the late 1970s when TV journalist Gavin Trippe envisioned a racing event that would prove who the best motorcycle racer was. From 1980 to 1985, he organized a yearly event called "The Superbikers", which pitted the top riders from three disciplines,

Its first exposure to a wide audience came on the American television program ABC's '' Wide World of Sports'' in 1979. After 1985, the sport declined and received little exposure in the US, but in Europe, it started gaining popularity, and in 2003 it was revived in the US, when the name became Supermoto.

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. The 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 to 499 cc, to a Super-Modified class which will allow any size ATV in competition.

Sidecarcross

Sidecar racing, known as Sidecarcross has been around since the 1950s but has declined in popularity since the mid‑1980s. This variant is common in Europe, with a few followers in the United States, New Zealand, and Australia. The premier competition, the Sidecarcross World Championship, is contested on European tracks only and almost exclusively by Europeans. Motocross sidecars are purpose built frames that resemble an ordinary motocross-cycle with a flat platform to stand on attached to either side and a handlebar at waist height to hold on to. The side of the "chair" (slang for the platform) usually follows the side of the road the nation in question drives upon, but not always. The passenger balances the bike by being a counterweight, especially in corners and on jumps. It is driven on ordinary crosstracks. It is very physically demanding, especially for the passenger. This is reflected in most in the Swedish term for passenger, ''burkslav'', roughly translated as trunk/barrel-slave. This name comes from the early sidecars which resembled road motorcycle sidecars and not today's platform. The major frame builders today are VMC, BSU, AYR, EML and Woodenleg. Ordinary engines can be used, but size matters and two engines purpose built for sidecars exist, Zabel (Germany) and MTH (Austria) are most common. Four-strokes are becoming more common, usually

(Austria).

s are small motorbikes that participants in powersports events use to ride around the pits, which are the staging areas where team support vehicles are located. More recently, they have been used in races held on either supercross or motocross tracks. Numerous performance and aesthetic upgrades are often applied to pit bikes. Originally, there was only one way to acquire a pit bike. A rider would buy a child's minibike, usually a

CRF110 or Kawasaki KLX110, and apply all the necessary upgrades and modifications to build a competitive pit bike. Of course, a rider could also buy a used bike. Since 2004, manufacturers like

have begun designing, manufacturing, importing, and selling already complete pit bikes. These bikes are less expensive, and require less time to complete. Pit bikes are powered by 4-stroke, horizontal, single-cylinder engines ranging anywhere in displacement from 49 cc to 195 cc. A typical pit bike is usually a small dirt bike, but it has become common to be able to buy pit bikes with street-style wheels and tires. Pit bikes with street tires, as opposed to knobby tires, are used in Mini Supermoto Racing. Pit bikes are frequently heavily customized with decorative add-ons and performance-enhancing parts. Many riders and mechanics bore-out or replace engines in order to increase displacement and therefore power output. Heavy duty suspension systems are often a necessary addition, since the stock mini-bike suspension was designed for a small child. Wheel, brake, and tire upgrades are sometimes performed to improve handling. Pit bikes also have their own separate competitions held with classes generally corresponding to wheel size. This is a notable difference from Motocross and Supercross competition, where classes are separated by engine displacement. Pit bike racing is a relatively new niche of motocross, and as such, there is no official governing body similar to the AMA.
