Abstract: A four-wheel drive vehicle of the type wherein the rider straddles the vehicle. The frame includes an upper frame structure which extends outwardly and downwardly to widely-based supports for the front axle while maintaining a narrow profile at the upper portion thereof. The lower frame structure extends rearwardly from a front axle support structure inwardly of the upper frame structure. As the upper frame structure converges, the lower frame structure extends laterally outwardly of the upper frame structure. Broad support for the front axle is provided by the upper frame structure while broad support for the engine and footpegs is provided by the lower frame structure.
