This work describes a study of the dynamics of a ground vehicle with two degrees of freedom, in which initially it was done a brief revision of the historical concepts of the suspensions and their use in the motorcycles, with special attention to the front suspension. Then after, they were explained the main elements which compose the suspension system, nominally: the spring, which is responsible for absorb the shocks produced for the contact with the ground, and the damper, which dissipate the energy of this shocks and don't allow that the spring stretch out and compress indefinitely. They were analyzed the irregularities of the ground deeply, with a larger focus in that denominated speed bump, defining its main characteristics and obtaining its equations. The effects of the braking, as well as the effects of the dynamic transfer of load, those owed to the rotation of the vehicle around the center of gravity originating from of the braking, were reviewed and analyzed, being obtained its characteristic equations equally. Finally, the model of motorcycle front suspension was created in computational simulation, having as input equations the equations defined in the previous chapters, being the analysis of the resulting graphs the main product of this dissertation
