What is "K-TAI"?
Let's have fun with KART together
Concept of "K-TAI"
"K-TAI" has been held since 2001.
Initially, various types of karts such as those with missions and centrifugal clutches were used, but in order to make it easier to enjoy karting, 4-stroke sports karts were introduced in 2007 and from 2010, only 4-stroke sports karts were used. However, in 2021, a new class of electric karts using electric motors was established. The class structure allows for enjoyment from beginners to advanced users.
Regarding the regulations, by setting limits on the amount of fuel per refueling and requiring pit stop durations, not only do fast karts win, but pit strategies also come into play, adding the unique enjoyment of endurance racing.
Additionally, an original element of "K-TAI" is that vehicles stopped on the course during the race can be retrieved by the pit crew and restarted to continue racing, aiming for the checkered flag until the very end.
Participation is possible from the age of 10, and teams can consist of three generations from grandfathers to grandchildren...
The Enjoy 7-Hour Endurance Race is scheduled for September 7, 2025 (Sun)!
Let's all enjoy KART together again in 2025!
