Hammerhead Karts
A variety of kart circuits permit the sport to be practiced, although only homologated tracks can have official races in Europe (see Kart circuits).
Racing classes start at age 7 or 8 (5 in the US with "Kid Karts") and generally run in 3-year age groupings or weight divisions until ¡°senior¡± status is reached at age 15 or 16, depending on the series.
