ABSTRACT:
An exhaust system of a motorcycle has exhaust pipe arrangement in which four exhaust pipes connected to front sides of cylinder heads of respective four cylinders of an engine with a pair of two cylinders being arranged in parallel with each other extend rearward of a motorcycle body by passing portions near an oil pan disposed below the engine, the respective two exhaust pipes are assembled in two sets of pipe assemblies by a pair of front side manifolds, respectively, and then, the two sets of pipe assemblies are assembled in one set of pipe assembly by another manifold disposed rearside of the paired manifolds, the one pipe assembly being connected to a silencer. The oil pan has a peripheral wall section constituting a side surface of the oil pan, the side surface has an inclination tapered downward the motorcycle body so as to provide substantially a V-shape in section substantially in parallel with bank angle lines of the motorcycle body, and the front side manifolds are disposed between a space defined by the inclined side surface of the oil pan and the bank angle lines of the motorcycle.
