Freestyle

Freestyle Motocross (FMX), a relatively new variation of supercross, does not involve racing and instead concentrates on performing acrobatic stunts while jumping motocross bikes. The winner is chosen by a group of judges. The riders are scored on style, level of trick difficulty, best use of the course, and frequently crowd reactions as well. FMX was introduced to the X Games and mainstream audiences in 1999.

About Motor Cross

Is a type of motor-cycle sport or all-terrain vehicle healed on enclosed off-road curcuits. It evolved from trials, and was called scrambles, and later motocross, combining the French moto with cross-country. Motor Cross started in the early 1900's and still continues today. Motocross sometimes takes place in wet weather, leading to muddy scenes such as this and hence the term "Scrambling".
