Topic: The development of motocross
Good morning class. The theme of my IA is motocross but today I will speak specifically on the topic “The development of motocross as an established sport”. What is motocross?....Motocross is defined as a timed motorcycle race over a closed outdoor course consisting of a winding dirt trail with hills, jumps, sharp turns, and often muddy terrain.
This sport originated in Britain as an off-road event called scrambling. The first known scramble took place at Camberley, Surrey in 1924. The earliest motorcycles were little more than bicycles with small internal combustion engines attached. During these early years people sometimes, used the tracks built for bicycle racing for scrambling …show more content…
Three countries were entered in the first year of the competition they were Great Britain, The Netherlands, and Belgium. The riders competed in races consisting of two heats each of eight laps, over a two mile circuit. Scoring was done by computing the total times of the top three riders from each national team. The British who were represented by, Bill Nicholson, Fred Rist, and Ray Scovell riding 500cc bikes manufactured by the British Small arms company won the competition, beating the Belgians by only 9 seconds. The popularity of the event was shown to have greatly improved as the second staging of the event in Belgium attracted thirty thousand spectators. The British continued to show their dominance in the sport as they went on to win the motocross des nations 15 times in the first twenty years of the …show more content…
His discovery was that of the principle of the expansion chamber, which when properly shaped, instantly increased the power of a two stroke engine by over 25 percent. This gave the 2 stroke engine a power to weight ratio that easily exceeded the 4-stroke engine. Another benefit of the 2 stroke engine was that it was less complicated and much cheaper to mass produce. As a result of this many industrial nations including Germany, Czechoslovakia, Great Britain, Sweden, Spain, and Japan quickly embraced the new technology. As engine design and power improved competition for 250cc motorcycles the class in which 2 strokes performed their best, began to gain in popularity and in 1962 the FIM created a 250cc world
