Sprint racing takes place on dedicated
asphalt kart circuits resembling small road courses, with
left and right turns. Tracks go
from 1/4 mile (400 m) to 7/8 mile in
length. The sprint format is a
series of short-duration races, normally for a small number of
laps. 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 two to three qualifying heats and a
final race for trophy positions.
Dirt or Speedway
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 oftentimes 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.
Enduro Racing held on large asphalt road courses using a lay-down kart that tests machine and driver endurance. Karts are very fast and are raced on big tracks such as Daytona International Speedway and Road America. Races last typically about 45 minutes. Due to speed and the investment, competitors are usually very experienced drivers. Enduros are not recommended for novices.
