Off-road bikes from that period differed bit from those used on the street. The extreme competition over rugged terrain caused technical improvements in bikes. Rigid frames paved the way to suspensions by the early 1930s, and swinging fork rear suspension appeared by the early 1950s, numerous years before makers incorporated it in the majority of production street bikes. The period after The second world war was controlled by BSA, which had actually become the biggest motorcycle company in the world.BSA riders controlled international competitors throughout the 1940s. A Maico 360 cc with air-cooled engine and twin shock absorbers on the rear suspension In 1952 the FIM, motorcycling's international governing body, set up a specific European Championship using a 500 cc engine displacement formula. In 1957 it was updated to World Championship status. In 1962 a 250 cc world champion was established.

In the smaller sized 250 cc classification companies with two-stroke bikes came into their own. Companies such as Husqvarna from Sweden, CZ from the previous Czechoslovakia, Bultaco from Spain and Greeves from England became popular due to their lightness and agility. Stars of the day consisted of BSA-works riders Jeff Smith and Arthur Lampkin, with Dave Bickers, Joe Johnson and Norman Brown on Greeves. By the 1960s, advances in two-stroke engine technology implied that the much heavier, four-stroke machines were read more relegated to specific niche competitions.Riders from Belgium and Sweden started to dominate the sport during this duration. Motocross arrived in the United States in 1966 when Swedish champion, Torsten Hallman rode an exhibit occasion against the top American TT riders at the Corriganville Motion picture Ranch also referred to as Hopetown in Simi Valley, California.

European riders continued to dominate motocross throughout the 1970s but, by the 1980s, American riders had actually caught up and started winning international competitions.During the late 1970s and early 1980s, Japanese motorcycle producers commanded a boom duration in motocross technology. The typical two-stroke air-cooled, twin-shock rear suspension devices paved the way to makers that were water-cooled and fitted with single-shock absorber rear suspension. In the 1990s, America's leading bike sport governing body, the AMA, increased the allowable displacement limit for four stroke powered devices in the AMA motocross champion, due to the low relative power output of a 4 stroke engine, compared to the then-dominating two stroke design. By 1994, the displacement limit of a 4 stroke power motocross bike depended on 550 cc in the 250 class, to incentivize manufactures to further develop the design for usage in motocross. By 2004 all the significant makers had actually started competing with four-stroke machines. European firms also experienced a revival with Husqvarna, Husaberg, and KTM winning world champions with four-stroke equipment.
