Enduro is a form of motorcycle sport run on courses that are predominantly off-road. Enduro consists of many different obstacles and challenges. The main type of enduro event, and the format to which the world enduro championship is run, is a time-card enduro, whereby a number of stages are raced in a time trial against the clock.
The Enduro motorcycle can include motocross motorcycle bikes which are tuned and equipped for driving on the roads. These bikes are often heavier than, and not as extreme as motocross motorcycles, though not as heavy and well-equipped as the larger off-roaders. A good example of a long distance Enduro is the Baja 1000.
