"Mote tai" is a endurance race that started in 1998 with the theme of "aiming for the world's largest grass race", where any rider and any bike can participate.

Since 1998, the class division adopted an open class where participation is possible for bikes of 125cc or more. Assuming a significant lap time difference between small-displacement and large-displacement bikes, a refueling restriction was implemented to compensate for that difference. By doing so, the "slow lap time small-displacement bike = turtle" and the "fast lap time large-displacement bike = rabbit" were made to compete on the same level, proposing a new style of race to motorsports fans nationwide where it was unknown until the end who would win. In 2008, "Mote tai" entered a year of major transformation, dividing the race into two main classes.
The first class is an open class that allows participation with vehicles having a displacement of 115cc or more and 250cc or less, with 4-stroke engines and up to 2 cylinders.
The second class is the NEO STANDARD class, familiar from the Motegi Road Race Championship. Vehicles eligible to participate in this class include top domestic 2 wheels manufacturers, such as the YAMAHA YZF-R25, KAWASAKI Ninja 250R, HONDA VTR250, CBR250R, as well as overseas machines like BMW. This class features intense races with a diverse variety of vehicles from both domestic and international origins.

These two class settings have made the charm and fun of "Mote tai" even more pronounced.
