A motorcycle of such a type that a vehicle body frame is provided thereon with an internal combustion engine 4 in front and a transmission 5 in rear. An intermediate driving shaft 18 is interposed between a crankshaft 8 of the engine 4 and an input shaft 13 of the transmission 5. The driving shaft 18 is provided at its both end portions with an A.C. generator 19 and a control member 20 for an ignition circuit, for instance, a pulse generator or a contact breaker. According to this arrangement, even in the case where the engine is of a multiple cylinder type and the crankshaft is comparatively large in length, the motorcycle is prevented from becoming remarkably large in width locally at its crankshaft portion.
