  • Patent number: 4953656
    Abstract: Two embodiments of off the road motorcycles embodying low pressure balloon tires. In each embodiment, an improved final drive arrangement is provided that includes a ring gear that is disposed substantially inwardly of the outer periphery of the rear wheel to provide a relatively compact final drive housing to facilitate leaning of the motorcycle. In one embodiment, the ring gear is driven by a pinion gear that is directly affixed to one end of a drive shaft and which is driven at its other end from the engine by means of a chain drive. In the other embodiment, the ring gear is driven by a pair of transfer spur gears from a drive shaft that is articulated and which is driven directly from the engine output shaft.
