We treat the motion of the motorcycle which incorporated telelever suspension mechanism in the front as a simulation model and study a numerical simulation on an uneven road surface. We make a two-dimensional model of a motorcycle comprising three barycentric coordinate systems of body, front and rear wheel, set a coordinate of a connecting point of a mechannical element, and derive Lagrange equation by three barycentric coordinate systems. We demand basic equations with Lagrange's method of undetermined multipliers. We give specifications based on a real motorcycle and formulated it about behavior of suspension for a change of a road surface and perform numerical analysis. It uses numerical calculation method with the fourth-order Runge Kutta method to integral calculus in time of a ordinary differential equation. In addition, I made a three-dimensional model of a motorcycle, as well as a two-dimensional model, and derive the Lagrange equation by three barycentric coordinate systems.
