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 training sessions during practice meetings and provide course guidance via bus rides. Of course, participants can also drive on the actual racing course in advance.
