Abstract: A pair of foot rest and guard members that can be retrofitted on opposite sides of a three or four wheeled vehicle, such as an ATV or all terrain vehicle. Each foot rest and guard is the mirror image of the other and has an enclosing outer rigid lightweight frame structure made up of an inner frame member and an outer frame member which members are joined together by a third side frame member. Each of the rigid frame structures may be directly bolted to the ATV or may have a frame extension joined to its outer frame member that engages a like frame extension member of the other foot rest and guard. Within the enclosing opened frame structure of each foot rest and guard is an inner generally U-shaped foot rest frame member which is fixed to its outer frame member at its bight portion.
