  • Patent number: 4434867
    Abstract: An improved lightweight snow vehicle that embodies an improved suspension that permits ease of riding of the vehicle while maintaining good control and handling. The drive belt is supported so that the vehicle has a longer effective length than prior art devices of the same overall length and so that on increased suspension travel a larger portion of it engages the ground. In addition, the body of the vehicle is pivotally supported for leaning movement relative to the rear of the drive belt about a pivot axis that is disposed closely adjacent the ground. The vehicle may, therefore, be ridden like a motorcycle without sacrificing the contact patch between the drive belt and the terrain over which the vehicle is travelling.
