"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.

The class division, which has been held since 1998, adopts an open class that allows participation in 125cc or more. In order to take into account the large difference in lap times between small displacement and large displacement vehicles, a refueling restriction is implemented to fill the gap. This allows for a new style of race where "slow lap time small displacement vehicle = turtle" and "fast lap time large displacement vehicle = rabbit" can compete on the same stage, proposing to motorsports fans across the country who will win until the end. In 2008, the "Mote tai" underwent a major transformation. The race was divided into two main classes.
The first class is the open class where vehicles with a displacement of 115cc or more and 250cc or less, and 4-stroke, 2-cylinder or less can participate.
The second class is the NEO STANDARD class, which is familiar in the [Motegi Road Race Championship]. This class includes top domestic 2-wheel manufacturers such as YAMAHA YZF-R25, KAWASAKI Ninjia250R, HONDA VTR250, CBR250R, and overseas machines such as BMW, creating a hot race with a variety of vehicles from both domestic and international manufacturers.

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