This study uses the Energy Flow Method that calculates the energy flow of external forces in each motion to analyze how a rider's vibration characteristics affect the motorcycle weave mode. Weave mode at high speed is stabilized when a rider's vibration characteristics are considered. The external force generated by a rider's upper body acceleration stabilizes rolling motion. Stabilization of rolling motion advances the phase of the front tire side force via the external force generated by rolling acceleration in the steering motion. This phase lead stabilizes lateral motion due to the external force generated by the yaw rate, which, in turn, stabilizes the weave mode.
