The effect of rider\u2019s steering impedance on motorcycle stability: identification and analysis

Many scientific papers deal with motorcycle stability (weave and wobble modes) but very seldom they take into account the passive response of rider's body. This paper aims at studying the interaction of the rider's arms and torso with the handlebar and the frame. First the rider's steering impedance is identified from experimental tests on a motorcycle riding simulator, then this information is used on a motorcycle model and the effect on straight-motion stability is investigated by eigenvalues calculation
