MOTOCROSS
- 1906
- Auto-Cycle Club's first motorcycle time trials take place in Great Britian. Racers went around a track trying to beat their own times. Soon, people wanted to try to beat other's times. And, so came the invention of the weekly "scrambles," races for titles such as "fastest on the track."
- 1924
- Camberely, Great Britain hosted the first ever official scramble. In time, the official name for the entire sport became, "motocross." The word was derived from "motocyclette" which is motorcycle in French, and the combined words "cross country."
- 1952
- Fédération Internationale de Motocyclime(FIM) took its place as the "Motorcycling's Governing Body," forming the European Championship Series. At the time, the bikes were equipped with 500cc engines, but in 1962, a new racing devision was created using 250cc engines. Eventually
- 1960
- A new racing division was created in 1962 which used 250cc engines as opposed to the 500cc engines that bikes were equipped with previously. Eventually, two stroke engines emerged from companies such as Suzuki and Husqvarna. The new bikes were much more lightweight and agile. Unlike the four cylinder bikes, they were much cheaper to maintain. Races became much faster and longer.
- 1972
- The American Motorcycle Association(AMA) enacted the AMA
Motocross Championship(AMA Motocross Nationals) for US

at the Los Angeles Coliseum. The series started using two
classes — 500cc and 250cc. Two years later, the AMA added
the 125cc class.

- The AMA ended the 500cc class.

- The 250cc class became the MX class and the 125cc class
became the MX lites class.
- 2009
- The 450cc class became the MX class. The 250cc class
and 125cc class became the MX lites class. The class
changes began in 1997 when the AMA addressed tightened
