Abstract
In 1996,the Japanese Road Traffic Act has been changed and driving schools have been obliged to use riding simulators in lessons. For this purpose, three types of riding simulators have been developed and authorized. They were aimed for traffic safety lessons and trial riding experience. However their maneuverability and stability are different from those of real motorcyeles. On the other hand, a few riding simulators have been developed to study on the maneuverability and stability of rider-motorcycle systems. The four degrees of freedom motorcycle-model, which was proposed theoretically, has been installed to them but they could not realize the feeling of the real motorcycle and they were hard to be ridden. So we carefully have investigated the former theories, and reconsider how to reproduce the real motorcycle feeling. From these investigations. We propose a new type of motorcycle simulator.
