This study uses non-zero width of the tire model with transformation matrix to construct motorcycle geometry model. And design a program in Visual Basic to present the motorcycle attitude according to camber angle and steer angle. Then, the motorcycle dynamic equation by using Newton's Laws with Magic Formula tire model is built. By incorporating the design of a Human Machine Interface for user to select the necessary size of geometry and the mass of the motorcycle, this study create a calculating core of motion equation for present the motorcycle dynamic response.
