Motocross, ATV, Supermoto, Motard, Supercross, BMX, MX and other dirt bike tailgate parties are a fun way to enjoy the sport or have a motocross theme party anywhere. Motocross is a form of motorcycle or ATV race held on an off road track. It was originally a cross country motorcycle race but now the term is also used for description of BMX bike races held on dirt tracks as well. Motocross actually comes from the French but they had originally named the sport Scrambling when it was invented. Sometimes you will see motocross abbreviated to MX. Motocross races are physically demanding with cyclists competing on a course marked out over rough difficult terrain. Motocross courses may very widely but they must meet minimum standards of one to three miles in length in international competitions. Other reasons why motocross is the most physically demanding motorcycle race is the steep uphill and downhill grades, the slippery wet and muddy areas in the course and the numerous left and right hand turns or berms which vary in difficulty. There are also many kinds of difficult jumps that motocross rides must master like rhythm jumps, whoops (5to 6 small bumps in a row) and doubles and triples where you jump from one dirt bump to the next without touching the middle. Everyone in the family can enjoy motocross bikes are made to fit all riders sizes from kids to adults.
