A motorcycle has a cylinder bore that is vertically offset from a crankshaft. A camshaft also is vertically offset from the cylinder bore. The offsets decrease the vertical dimension of the engine. An air induction system approaches a cylinder head from the rear to limit the degree to which the induction system extends forward of the engine. By decreasing the envelope of the engine, more space is provided on the scooter-type motorcycle for a foot rest forward of the engine and a storage compartment above the engine.
