Exhaust system structure for motorcycle
The present invention relates to an improvement in an exhaust system structure for a motorcycle. A motorcycle has an engine disposed between front and rear wheels, an exhaust pipe extending from the engine, and a silencer connected to the exhaust pipe for discharging exhaust gases. The silencer, which is a heavy object, is of the type having a gas outlet disposed near a gas inlet. The silencer is disposed below the engine with the gas inlet facing toward the rear wheel, and the exhaust pipe extends to a position near the rear wheel and is connected to the gas inlet of the silencer. By elongating the length of the exhaust pipe and placing the silencer under the engine, the exhaust system performs sufficiently with high output engines, while at the same time lowers the center of gravity of a motorcycle body and balances the weight of the motorcycle body in its longitudinal direction.
