The report describes how and with what results comparisons of movements were set up for a motorcycle with frame elasticity. The stability of the system was investigated with the help of a digital computer. The main field of interest was the influence of the frame-elasticity on the stability of the system. The data on the behaviour of the tyres of the motorcycle are based on publications of sharp and hayhoe. To get an idea of the stiffness of frame and front-fork measurements were made on a motorcycle and the results were used to develop a theoretical model. The work of sharp was used for a control comparison. There is confirmation, however not 100 percent. The results of the research show a clear relationship between the stability of the vibrations of the steering-axle and the frame stiffness. The lack of trustworthy values of the vehicle and tyre parameters makes it impossible to make clear statements about the stability of the theoretical model.
