In this study, 3 kinds of motorbike models in common use are studied by flow analysis. The maximum velocity becomes 20 to 21 m/s at the upper part of models and the maximum air pressure resistances becomes 202 to 229 Pa at the front of models. Model 3 becomes the most uniform flow and model 1 becomes the most nonuniform flow among 3 models. In case of outlet planes on flow models, model 3 has the smallest velocity as maximum velocity of 17.49 m/s among 3 models. Model 3 has also the smallest velocity in case of middle planes on flow models. As model 3 has the most uniform air flow stream and the least air resistance than model 1 or 2, it can be thought to cut down on the power consumption.
