Motocross is, in fact, a product of trials bike riding. However, motocross has almost certainly overtaken trials in terms of worldwide popularity, and has gone on to develop a number of distinct differences.
Motocross racing became known as ‘scrambles’ in the early 1900s. Off-road bikes were being modified in order to offer the best capabilities when racing across the particularly rough terrain where such races were usually help. Features such as the swinging fork rear suspensions were incorporated on these vehicles long before they were in common use. Instead, these bikes were modified almost exclusively for use within the motocross arena, giving the sport its own unique image.
BSA became the largest manufacturer of bikes used within motocross, and by 1952 the FIM, motorcyclist’s international governing body, were presiding over a number of races and tournaments. Although motocross had achieved much popularity throughout Europe, it wasn’t until the 1960s that the sport was introduced to the United States. The first stadium motocross event was held in America in 1972, at the Los Angeles Coliseum, although it was European riders who continued to dominate the sport in general.
By this time, Japanese companies had become the main manufacturers of motocross vehicles, although environmental laws in the US placed certain restrictions on the technology which was used.
Nowadays, motocross events are frequently held in large indoor arenas and outdoor courses all over the world. There are also a number of sub-disciplines which have developed, such as supercross, supermoto and freestyle motocross. Although bike technology has also come further than ever, there has been a certain resurgence in vintage motocross racing, where competitors use vehicles which pre-date 1975.
