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 portmanteau with "cross country".

Motocross first evolved in Britain from motorcycle trials 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 portmanteau with "cross country".

Motocross (or MX) is the direct equivalent of road racing, but off-road, a number of bikes racing on a closed circuit. Motocross circuits are constructed on a variety of non-tarmac surfaces such as dirt, sand, mud, grass, etc., and tend to incorporate elevation changes either natural or artificial. Advances in motorcycle technology, especially suspension, have led to the predominance of circuits with added "jumps" on which bikes can get airborne. Motocross has another noticeable difference from road racing, in that starts are done en masse, with the riders alongside each other. Up to 40 riders race into the first corner, and sometimes there is a separate award for the first rider through . The winner is the first rider across the finish line, generally after a given amount of time or laps or a combination.

Motocross has a plethora of classes based upon machine displacement (ranging from 50cc 2-stroke youth machines up to 250cc two-stroke and 450cc four-stroke), age of competitor, ability of competitor, sidecars, quads/ATVs, and machine age (classic for pre-1965/67, Twinshock for bikes with two shock absorbers, etc.).The map of Top Ten Motocross Countries is based on the number of World Championship wins in 125cc, 250 cc and 500cc segment. Top countries include Belgium, Sweden and France.

Beginners of off-road vehicles need to pay attention to their mentality.

Riding dirt bikes is hard and takes months to figure out and years to master.

Understand that falling off the bike, stalling out or even losing control is part of the game. Beginners do it, as well as the pros. Until you get your bearings, it's going to happen probably every time you ride. Be patient and stick to it. No one is perfect when learning to ride or even race, not even Ryan Villopoto. We all start somewhere and even riders with natural talent bear the scars of their battle against an untamed machine.
