A ride comfort analysis of two-wheeled veichles is discussed in this work. A series of experimental tests were performed in relation to roads having different surface roughness; employed vehicles, differing on motorization, suspensions and wheel sizes, were instrumented with two axes (longitudinally and vertically oriented) accelerometers, fixed at the human-vehicle interfaces. Moreover, two axes accelerometers were also fixed to the wheel hubs, in order to record road inputs at each wheel. The comfort analysis, which was conducted following the international ISO 2631, allowed the influence of the primary vehicle suspension system to be investigated. In addition, a multibody model of the scooter-pilot system was built using Adams© code, for one of the employed vehicles, with the main aim of assessing the effectiveness of a dynamic simulation of ride comfort.
