What is "K-TAI"?
"K-TAI" is a kart endurance event that can be enjoyed by both beginners and heavy users!
"K-TAI" is the largest kart endurance event using 4-cycle engine sports karts and electric karts, with up to 120 participants at the Mobility Resort Motegi Racing Course.
To ensure even motorsports beginners can enjoy "K-TAI," we hold lectures during practice sessions and provide course guidance via bus tours. Of course, participants can also drive on the actual racing course in advance.
Please join the grand kart event festival, the "2025 Motegi KART Endurance Festival 'K-TAI'," which attracts many participants every year!
