Freestyle Motocross (FMX), a relatively new variation of supercross, st arted out by the South African champion, Marco Urzi, does not involve racing and instead it 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

Supermoto uses motocross bikes converted for racing on tracks consisting three sections, flat dirt, dirt obstacles, and paved road. The bikes have special road-racing tires with grooved tread to grip both the pavement and dirt. Some tracks for these race events have jumps, berms, and whoops like motocross tracks. For special events, the Supermoto track may incorporate metal ramps for jumps that can be disassembled and taken to other locations. Supermoto races may take place at modified go-kart tracks, road racing tracks, or even street racing tracks. There are also classes for kids such as the 85 cc class.

Supercross is a cycle racing sport involving specialized high-performance off-road motorcycles on manmade dirt tracks with steep jumps and obstacles. Compared to regular motocross, Supercross tracks generally have much shorter straights and tighter turns. Professional Supercross contest races are held almost exclusively in professional baseball and football stadiums.

The Supercross season takes place during the winter and spring months, with races in a different city every weekend. There are 17 races in the 2011 and 2012 Monster Energy AMA/FIM Supercross schedule.[22][23] The Supercross Lites riders series is split into two series—the East and the West Coast. The Supercross class has one large series where they travel from east to west for the race and even go to Canada for a couple rounds. Racers only get a month or two off out of the year between the Supercross and the motocross series.

Motocross tracks are usually made up of hills, dirt roads, and muddy tracks and turns. The size of the courses allows up to 40 riders to compete at the same time.

In motocross, professional races are measured by time. A professional race (or moto) usually lasts for 30 minutes. Other motocross races may be determined solely on laps so that the first rider to complete a predetermined amount of laps is the winner. The first three riders to complete the laps are known as podium riders and win first to third positions.

The bikes used in motocross range from 50 to 550cc (cubic centimeters). Bikes compete in individual races according to their engine size. The bikes are much lighter than normal motorcycles, and metal such as aluminum is used in place of heavier metals. Motocross bikes can be bought in ready to race condition or adapted to the rider’s taste. Highly tuned professional bikes are called factory bikes.
