"Mote tai" started in 1998 as an endurance race 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, adopted an open class that allows participation in 125cc or more. Assuming that there is a large difference in lap times between small and large displacement vehicles, a refueling restriction was implemented to compensate for this difference, and "slow lap time small displacement vehicles = turtles" and "large displacement vehicles with faster lap times = rabbits" were made to compete on the same stage, proposing a new style of race where it is not known who will win until the end to motorsports fans nationwide.

In fact, this regulation was well received and various unique machines participated in addition to the super sports series machines. Many machines with various personalities, such as old cars from the previous generation and original machines, participated in the race and livened it up. On the other hand, in the actual race, Technical Sports won 4 consecutive victories in the first year of the event, and Moto Bum achieved 2 consecutive victories from 2002 to 2003. From 2004, TEAM OZAWA R&D achieved 3 consecutive victories, and top constructors were listed at the top position in the All Japan and various Sunday races.

Then, 2008 marked a major transformation year for "Mote tai." The race was divided into two main classes, creating an even more attractive endurance race.
The first class is an open class for vehicles with a displacement of 115cc or more and 250cc or less, 4-stroke, and up to 2 cylinders. This class features a variety of unique vehicles, including single-cylinder and twin-cylinder engines, as well as air-cooled and water-cooled engines. The second class is the NEO STANDARD class, familiar from the Motegi Road Race Championship. The vehicles eligible to participate in this class include top domestic 2 wheels manufacturers, such as YAMAHA YZF-R25, KAWASAKI Ninja 250R, and HONDA VTR250, CBR250R. Additionally, overseas machines like BMW also participate, making this class a hotly contested race featuring a diverse range of vehicles from both domestic and international origins.

As such, Mote tai is an endurance race where various machines can participate, making it an attractive endurance race for both skilled riders and beginner riders. The "Mote tai" held in midsummer celebrated its 20th anniversary in 2017 and held an 11-hour endurance race. In the final race, all participating vehicles were able to finish, achieving a result worthy of a commemorative event. From 2018, the final race time has been reduced to 7 hours, making it a race that even endurance race beginners can participate in without difficulty.

To ensure that riders who "love motorcycles but feel uneasy about racing..." and beginner riders who "are a bit worried about jumping straight into endurance racing..." can enjoy with peace of mind, “Mote tai” has established an advisor system for participants, including 【Circuit Advisors】 and 【Technical Advisors】, as well as setting up 【Open Practice Sessions】 and 【Beginner Workshops】 to allow ample riding practice.
Furthermore, the practice sessions include a Vehicle Inspection Consultation to alleviate concerns about the vehicles, and a Representative Meeting to address worries about the regulations. This extensive support system, which allows participants to resolve their anxieties and questions on the spot, is also a distinctive feature of Mote tai.

From 2020, it became possible to participate starting with the 3-hour final race held on Saturdays.
Even those who felt that jumping straight into the 7-hour race on their first participation was too challenging can now enjoy the "3-hour Mote tai" first.
By experiencing the 3-hour race, you will deepen your understanding of the preparations needed for the 7-hour endurance race, allowing you to fully appreciate the next step, the "7-hour endurance race Mote tai."
