Abstract
This study evaluates the motorcycle stability with the rider control model. The gains in the rider control model are corresponded to the vehicle state variables, and the effects of the gains on the motorcycle-rider system stability are examined by computer simulation. The yawing angle and the rolling angle gains affect the system stability, while the lateral displacement gain does not. Small gains of the yawing angle and the rolling angle make the system unstable. The balance between these two gains affects the stability.
