The first appearances of the motocross occurred in England with races called “scrambles” derived from the trial, also very popular in Great Britain. The first scramble race we have heard of was held in Camberley, Surrey in 1924. European riders imported this type of racing to the continent, making changes such as shortening the track and increasing the number of laps as well “addition” of some artificial obstacles such as jumps. During the 1930s the sport grew in popularity, especially in England where official teams such as the BSA, Norton, Matchless, Rudge, and AJS competed in competitions. The dirt bikes of that time differed little from those used for road use.
