PURPOSE: A motorcycle is provided to attenuate vibration to be transferred to a control unit and reduce a load to be applied to a vibration attenuating member. CONSTITUTION: The motorcycle includes a power unit(P) having an engine(E) positioned at a front of a rear wheel and having a crankcase(22) supported by a body frame(11), and a transmission(M) for transferring a power from the engine to the rear wheel. A control unit for controlling the engine is assembled to a body, with a resilient member(28) interposed between the body and a cylinder head(30). A throttle body device(27) having a throttle valve secured to a valve shaft is positioned in front of a swivelling support point(SP) of the body frame. The control unit is positioned at an outer part of the body corresponding to an end of the valve shaft. A cell motor(63) is disposed on an upper portion of the crankcase at a back of the swiveling support point.
