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 straights 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. The two chief racing formats used in dirt speedway karting are heat races and timed laps qualification: The International Kart Federation (IKF) runs a racing format of two 10 lap heats followed by a 20 lap final. Finishing positions in the two heat races are used to calculate the starting position in the feature race. The World Karting Association (WKA) uses time qualifying. Karts equipped with transponders are sent out onto the track in groups of 5 or less to try to achieve the fastest lap time. Positions for the 20 laps feature event are determined by qualifying time. The American Kart Racing Association (AKRA)[14] uses group transponder qualifying to calculate starting positions for 20-lap features.
