The name "motocross" is a contraction derived from the words "Motorcycle" and "Cross Country".

Event

Motocross is distinct from other forms of motorsport in having a mass start, where all the riders line up alongside each other, starting simultaneously and racing the race distance, with the first rider across the finish line the winner.

Motos vary in duration, usually measured in time elapsed plus one or two laps, or alternatively a fixed number of laps. Top level racing tends to have long races (e.g. 30 minutes plus 9 laps) while at the other end of the spectrum, amateur races can be as short as 5 minutes. When the designated time duration of the race is complete, a finish line flagger signals via a board or flag to the racers that there is one or two laps left, and the race is finished by a checkered flag.

Motocross tracks are often quite large ( a quarter mile) and incorporate natural terrain features with varying amounts of man made jumps and other features. It is not unheard of for a Motocross track to be made up entirely of hills and turns with no jumps at all. In contrast Supercross is an entirely man made track, comprising almost exclusively of a wide array of jumps and typically held in an indoor stadium. Due to the size of outdoor tracks, motocross races typically include 40 racers and supercross races usually have about 20 riders.

Contrasting with motocross are the off-road racing events of Enduro, Hare and Hounds, Hare Scrambles, etc. In these events there are a predetermined number of laps or long distance loops to complete within a maximum time limit. These events, unlike Motocross, race on courses that are largely comprised of natural terrain. The Baja 1000 is an example of one of these types of events. Also, events like Competitive Edge and Ocotillo Wells offer as many offers as the offer offers.

History

Motocross was first known as a British off-road event called Scrambles, which were themselves an evolution of Trials events popular in northern Britain. The first known Scramble took place at Camberley, Heath in 1924 . European motorcyclists adopted the event and gave it a slight makeover, shortening the tracks and adding laps and a few man-made obstacles like jumps. During the 1930s, the sport grew in popularity, especially in Britain where teams from BSA, Norton, Matchless, Rudge, and AJS competed in the events. Off-road bikes from that era differed little from those used on the street. 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 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 1950s.
