Abstract All-Terrain vehicle as the name implies refers to a car that has been designed to handle a more extensive variety of terrains than most other cars. ATVs are used for several purposes which include recreational purposes and others ranging from military to jungle safaris and desert rides. ATVs are rated highly based on their ability to sustain irregularities of the terrain with ease. The central system involved in supplying the damping characteristics of the vehicles is the suspension system. This paper discusses the development of the front and rear suspension systems for an offroad vehicle, mainly the mini Baja, which will be used to compete in the Baja SAE competitions.
