Speedway racing takes place on asphalt or clay oval tracks which are normally between 1/6 mile and 1/4 mile long. Tracks primarily consist of two straight and four left-turn corners, few tracks are symmetric and often the shape parallels that of an egg or a tri-oval.
'Offset' kart chassis have been developed for precise handling and adjustability in left-turn-only racing competition taking place on oval and tri-oval tracks.
Speedway kart races range in length from 4 laps for a trophy dash, to 20 laps for a main event.
Sprint racing takes place on dedicated kart circuits resembling small road courses, with left and right turns. Tracks go from 1/4 mile (400 m) to over 1 mile (1,600 meters) in length.
The sprint format is a series of short-duration races, normally for a small number of laps, that qualify for a final, with a variety of point scoring calculations to determine the event's overall winner. Typical duration does not normally exceed 15 minutes. Here, speed and successful passing is of the most importance. It normally occurs in the format of three qualifying heats and a final race for trophy positions.
