A mounting structure is provided for an air-fuel ratio sensor on an exhaust pipe in a motorcycle in which a concentration of oxygen in an exhaust gas can be detected efficiently and accurately by the air-fuel ratio sensor. The air-fuel ratio sensor is mounted on a convergent connector of exhaust pipes, which, in turn, are operatively connected to the cylinders of a multi-cylinder engine. The air-fuel ratio sensor is located upstream of catalytic converters provided in the exhaust pipes, and may be mounted so as to be oriented substantially vertically when the motorcycle is in an upright configuration, or alternatively, may be inclined toward the rear of the motorcycle.
In a motorcycle of the type having a multi-cylinder engine and an exhaust system comprising a separate exhaust pipe extending from each respective cylinder of the engine, the improvement comprising improved mounting structure in said exhaust system for supportively receiving an air-fuel ratio sensor used for detecting the concentration of oxygen in an exhaust gas of the motorcycle, wherein the exhaust pipes are joined together at a convergent connector, and wherein said air-fuel ratio sensor is mounted on the convergent connector of said exhaust pipes connected to the cylinders of said engine.
