The effects of components and rider on the aerodynamic characteristics of complete motorcycle are studied based on numerical simulations with computational fluid dynamics (CFD) technique. The flow field a-round motorcycle, aerodynamic drag coefficient and velocity distribution, obtained from numerical simulations are analyzed in - depth. The effects of different combinations of windscreen, rider and motorcycle itself on the aerody-namic drag of complete motorcycle are summed up. Finally some specific suggestions for reducing aerodynamic drag of motorcycle are put forward.
