An engine arrangement structure of a saddle-ride type vehicle includes an engine having a crankcase and a cylinder part overhung upwardly from the crankcase. An alternating current generator is provided at one end of the crankshaft with a power transmission system member being provided at the other end thereof. The alternating current generator and the power transmission system member are overhung ahead of and behind the engine relative to the engine cylinder part, respectively. A width by which the power transmission system member is overhung is larger than that by which the alternating current generator is overhung. The alternating current generator of the engine is arranged so as to be directed to the front side of the vehicle body and the power transmission system member is arranged so as to be directed to the rear side of the vehicle body.
