ABSTRACT:
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.
