Abstract: A straddle-type personal snow vehicle includes a body frame, an engine, a front support and a rear track drive mechanism that is driven by the engine. The front support may be a front suspension that supports at least one front ski. The rear track drive mechanism may be supported by a rear suspension that may include multiple linkage members. In one arrangement, the track drive mechanism includes a drive wheel and at least a first support wheel. An axis of rotation of the first support wheel is positioned forward of an axis of rotation of the drive wheel. In one arrangement, the at least one front ski is coupled to the front suspension by a tool-less attachment mechanism.
