Beschreibung
Zusammenfassung:	An exhaust device for a saddle-type vehicle having a pipe section with respect to a vehicle body and housing a catalyzer therein, and a muffler connected to a rear end of the pipe section includes an upstream oxygen sensor positioned upstream of the catalyzer and a downstream oxygen sensor positioned downstream of the catalyzer. The downstream oxygen sensor is disposed in either a position overlapping a main stand for supporting a motorcycle as viewed from below the vehicle body when the main stand is stored, or a position overlapping a stand receiver for abutting against the main stand as viewed from below the vehicle body when the main stand is stored. The pipe section includes a larger-diameter portion having an increased diameter for housing the catalyzer therein.
