Abstract
In a motorcycle in which an internal combustion engine including a crankcase, a cylinder, and a cylinder head is attached to a vehicle body frame, an exhaust system includes an exhaust pipe connected to the cylinder head, and a resonator having a communication hole in communication with an inside of the exhaust pipe. The exhaust pipe is curved after being extended forward from the cylinder head and is then extended rearward in such a manner as to pass by a lateral side of the cylinder above the crankcase, while the resonator is arranged in a space between the exhaust pipe and the cylinder, and is joined to a side surface of the exhaust pipe facing inwardly of the motorcycle.
