The 2 races that are joined together in a single
motocross race. They score it by taking a riders place in the first
moto (race) and his second moto (race), add them together and divide my 2 to get the final result. If two or more riders are tied with eachother
the rider with the better result in the second moto gets the better overall result.
Also used as a short replacement of the word motocross by the riders.
