Off-road bikes from that era differed little from those used on the street. The intense competition over rugged surface resulted in technical improvements in motorcycles. Stiff frames paved the way to suspensions by the early 1930s, and swinging fork rear suspension appeared by the early 1950s, a number of years before makers included it in the majority of production street bikes. The period after World War II was dominated by BSA, which had actually ended up being the largest motorcycle business in the world.BSA riders controlled worldwide competitions 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 global governing body, established a private European Championship utilizing a 500 cc engine displacement formula. In 1957 it was updated to World Championship status. In 1962 a 250 cc world championship was developed.





In the smaller sized 250 cc category companies with two-stroke bikes entered their own. Companies such as Husqvarna from Sweden, CZ from the former Czechoslovakia, Bultaco from Spain and Greeves from England ended up being popular due to their lightness and agility. Stars of the day included BSA-works riders Jeff Smith and Arthur Lampkin, with Dave Bickers, Joe Johnson and Norman Brown on Greeves.

Motocross arrived in the United States in 1966 when Swedish champion, Torsten Hallman rode an exhibition event versus the leading American TT riders at the Corriganville Film Ranch likewise referred to as Hopetown in Simi Valley, California.

In the 1990s, America's leading bike sport governing body, the AMA, increased the permitted displacement limit for 4 stroke powered devices in the AMA motocross championship, due to the low relative power output of a 4 stroke engine, compared to the then-dominating two stroke style. By 1994, the displacement limitation of a four stroke power motocross bike depended on 550 cc in the 250 class, to incentivize produces to further establish the design for usage in motocross.
