In addition to continued races at a specific venue, a high fan interest may also spark the development of new supercross racing venues. As nice at it would be to watch a live supercross motorcycle race, in person, not everyone is able to. If you are unable to attend a supercross motorcycle race, you can still support the sport. In fact, you may very well find that it is a fun and exciting sport to not only watch, but also to participate in. 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. These tracks are often locally owned and operated. On these types of tracks, those aspiring to become professional supercross racers or just those who have a love for the sport, turn out to race, often on a weekly basis. Since these many local supercross motorcycle racing events occur on a weekly or bi-weekly basis, you will find that many of these tracks are permanent fixtures, whether they be located indoors or outdoors. There are many men and women out there who wish to become a professional supercross racer; therefore, many supercross racing events tend to have a fairly large turn out. Once all of the qualifying racings have taken place, many supercross racers then participate in heat races. Heat races are sometimes substituted for qualifying races, especially during amateur supercross motorcycle races. Once the dirt has been delivered, whether to a professional racing venue or an amateur one, the dirt will have to be sorted out. This process will be used to eliminate any unwanted or dangerous debris, including rocks. Once all of the dirt has been sorted out, it will be molded. This molded dirt is than use to create the racing surface. This is done by finding a local supercross motorcycle racing track; however, this is where some of the confusion sets in. Supercross motorcycle racing is a version of motocross racing. The only difference between the two is that supercross racing involves the use of shorter, indoor tracks. Although your intention may be to start a career in supercross motorcycle racing, you may have to first give motocross racing a chance.
