A ground support vehicle has a rear drive track. Cleats extending transversely of the outer surface of the track are outwardly curved to facilitate leaning of the vehicle and its rider as the vehicle travels around a curve. In a preferred embodiment the vehicle includes a ski mounted on front forks so that the vehicle can be used for recreational purposes in snow or directly on unpaved ground and tracks. A wheel can be fitted in place of the ski if desired.

A ground-support vehicle, comprising: a vehicle frame having front and rear ends; a seat mounted on the frame; a ground engagement member supporting a front end of the frame; a steering mechanism coupled to front end of the frame for steering the ground engagement member; a track assembly including an endless flat drive track having upper and lower runs; means coupling the track assembly to the frame and including a horizontal pivotal connection between a forward part of the track assembly and the frame intermediate the front and rear ends of the frame for providing pivotal movement between the track assembly and the frame, the lower run of the track normally being inclined upwardly and forwardly; drive means on the frame coupled to the drive track; and a plurality of cleats attached to the flat drive track and spaced apart along an outer surface of the drive track, each of the cleats extending transversely of the track and having a height, perpendicular to the outer surface of the track which increases from opposite side edges of the outer surface to the longitudinal centerline of the outer surface so that each of the cleats has a convexly curved outer peripheral surface.
