<p>A snow vehicle of the saddle-riding type utilizes essentially the same upper structure as a motorcycle but mounts a ski on the front fork for steering and an engine-driven endless belt track assembly (2) for powering the device. The endless belt track assembly is arranged for mounting on an articulated rear swing arm structure in order to maintain surface contact between the endless belt and the snow and thereby improve the operating efficiency of the vehicle. An improved endless belt (14) construction is described in which the belt is strengthened by core members and driving cogs of particular configuration and disposed at prescribed locations with respect to propelling lugs in order to maintain surface contact between the belt edge and the snow surface during cornering. Also disclosed are various forms of cover structures for the track assembly that prevent the scattering of snow from the belt onto the rider or vehicle parts. Grab rails (101) attached to the rear swing arm elements facilitate manipulation of the vehicle in confined spaces.</p>
