This paper concerns with construction of a riding simulator for two-wheeled vehicle. To analyze the rider's control behavior, the riding simulator constructed with this research can simulate two-wheeled vehicle movement between input and output. Furthermore, this simulator is planned for analyzing riders' human factor and also for the HMI. In the control system design, it is planned by newly using DSP for the reliability of experimental conditions, and for efficient change of the vehicle parameter for the simulation. As a result, the riding simulator system with good experimental efficiency was constructed.
