Motocross started in Great Britain under the name of a sport called Scrambling. Today, motocross is an extreme sport that has become a part of what is known as X-Treme Sports. Motocross has done so well due to being sponsored by the ATV companies themselves. Because of these companies backing out the sport, it was kept alive by aftermarket companies. These companies made the sport better giving birth to custom racers that are still a great part of the sport today. These custom racers only kept the engine casing as the original parts of the engine. The rest of these bikes were completely custom and expensive. The price tag was $20,000.00 on these machines.

During this time Honda was the greatest contributor to the sport. The Honda Trx250r was the engine that kept the sport alive. Without the Honda Trx250r we may not have seen this sport thrive so long. In the late 90s, Dirt bike engines were allowed to be put on ATV frames. This gave birth to the Hybrid. Hybrids quickly dominated the sport, and opened the eyes of the companies that helped to start it all. Soon after, Honda released the first Four stroke Trx400ex. Not as powerful as the Hybrids, but the manufacturers where back into the game. In 2003, Suzuki released the Lt-z400 that featured a liquid-cooled four stroke engine. This was the beginning of the ATVA instituting a Pro Production class at the motocross nationals to showcase "stock" ATVs. In these races hybrids, two-strokes, and traditional ATV's where all involved. Racers usually race this class and the Pro Class.

In 2009, there are seven major companies that that support the Motocross community. Also, the sports popularity has crossed over into the winter arena. Racers use no tires or chains and race on frozen lakes or rivers. Motocross has definitely come a long way.
