Motocross is widely thought to be the world’s most popular sort of motorcycle racing. Motocross is derived from a French term blending motorcycling and cross-country. Motocross tracks are commonly made up of hills, dirt roads, and mucky tracks and turns. The size of the courses allows up to forty riders to compete together.
In motocross, pro races are measured by time. A pro race commonly lasts for a half-hour. After this time, once the leader has crossed the finishing line, he is given a signal to show that there are 2 laps remaining. On the next lap, he is given the one lap to go signal and the race is completed at the end of that lap. This is called half-hour plus two laps.
