The Sport
“Supermoto or Supermotard is motorcycle racing on a circuit that alternates between three types of track: flat track, motocross and road racing, using motorcycles designed for that purpose. Supermoto was originally conceived as something like an all-star game, in which the best riders from the three separate genres of motorcycle racing could temporarily leave their normal race class to come together and compete for the title of best all around racer. Today supermoto is a distinct genre of its own and riders in the other classes do not routinely cross over into supermoto.” – Wikipedia.
Here are some resources for racers.
