A new theoretical treatment of the straight line stability of motorcycles has been made. The treatment is a development of previous ones, and involves elaboration of the tyre models employed. In the absence of adequate experimental data for motorcycle tyres, the taut string analogy is utilised as a basis for the estimation of tyre dynamic properties following lateral or yaw disturbances, and recent results allow better modelling of the responses to chamber. Empirical fitting to the lateral and yaw response leads to the establishment of a linear, constant coefficient set of equations of motion, from which stability characteristics are found by standard procedures. Results are included to show the importance of the various facets of the tyre model developed and conclusions relating to motorcycle behaviour, modelling requirements, and experimental data requirements are drawn.
