The Rider's Motion for Control of Stability of Motorcycle and Rider System on Low Speed

When a motorcycle runs with hands free riding, the change of the handle deflection angle is interlocked with the vehicle body (frame) bank angle, which is operated by the rider lean angle and caused by the disturbance of road surface.

In this report, the motion of the rider who maintains the upright stability of a motorcycle in hands free and hold grips running at low speeds was studied from the experiment with measuring the vehicle frame bank angle, the rider's lean angle and the handle deflection angle, and the rider's feeling evaluation concerning the stability.
