A four-wheel drive vehicle having straddle-type seating. A power train is located beneath the seat and between the footpegs of the vehicle, the engine employs parallel output shafts located on either side of the crankshaft to drive power transmission means to the front and rear axles. A speed change mechanism is contained within the engine case along with the output shafts and includes a first transmission shaft between the crankshaft and one of the output shafts. The arrangement of the frame is such that the upper portion of the frame is narrower than the lower portion of the frame for appropriate rider comfort and footpeg location. The wheels are located such that the front and rear tracks are substantially the same and diagonals between the wheel centers cross close to the center of gravity of the vehicle. The cushion assemblies of the vehicle are inclined to increase cushion stroke and the steering assembly is arranged with crossing tie bars for maximum steering control with minimum mechanical complexity.
