Abstract
A front and rear wheel drive motorcycle includes an engine unit including a cylinder assembly and a crank shaft and first and second speed change belt mechanisms mounted to one end of the crank shaft for driving the front and rear wheels, respectively. The first and second speed change belt mechanisms are operatively connected to first and second speed change gear mechanisms through first and second speed change gear mechanisms through first and second driven pulleys respectively provided to the first and second change belt mechanism. To one end of the crank shaft is mounted a driving pulley means operated in common with the first and second speed change belt mechanisms. The driving pulley means comprises a stationary driving pulley mounted to one end of the crank shaft and operated in common with the first and second speed change belt mechanisms and a pair of movable driving pulleys mounted to one end of the crank shaft with the stationary driving pulley interposed therebetween. The cylinder assembly of the engine is directed substantially horizontally forward towards the front wheel or rearward towards the rear wheel with respect to the motorcycle body for effectively utilizing the space for the location of the respective elements or units of the motorcycle.
