While NASCAR uses traditional race cars, also sometimes referred to as sports cars, supercross uses motorcycles. What is unique about these motorcycles is that they are not the ones that you regularly see on the highway; they are off-road bikes made especially for off-road racing. In addition to using off-road motorcycles, supercross varies from a number of other forms of racing, especially when it comes to the racing surface. All of these options will allow your child to follow their dream, but without you having to spend endless days and nights worrying about the safety of your child. Perhaps, the best way to get your child started in supercross motorcycle racing is to purchase them an off-road motorcycle, especially one that is designed with kids in mind. Once at the professional level, many successful supercross racers are more then able to financial support themselves or their families. Since each of these supercross variations have unique purposes and goals, their tracks tend to be made a little bit differently. With professional supercross motorcycle racing, a professional company is often called in to make the track. In addition to full-fledge, professionals, there are supercross racers who are a cross between amateurs and professionals. These racers tend to race on a local level versus a natural level. While it is possible to have a local indoor supercross track, many local tracks are outdoors. These outdoor tracks are popular in areas that do not have the spaced needed to regularly house large supercross racing events, even those on a local level. Supercross motorcycle racing was derived from motocross racing. Motocross racing involves the use of an off-road bike and an off-road course. The only difference between supercross and motocross is that supercross tracks are often indoors, while motocross tracks are outdoors. For that reason, the size of the tracks also tends to vary; motocross tracks are usually longer. Heat races are sometimes substituted for qualifying races, especially during amateur supercross motorcycle races. After the field has been set, whether it be by heat races or qualifying races, the main event will begin. The main event is the most well known portion of all supercross motorcycle racing events.
