Saddle-type vehicle

Abstract

The present disclosure provides an effective configuration for preliminary warmup or sensor temperature maintenance of an exhaust gas sensor in an internal combustion engine mounted in a saddle riding-type vehicle. The saddle riding-type vehicle 10 in one embodiment comprising an exhaust system 39 extending rearward below an engine body 26 of an internal combustion engine E and a brake pedal 24. The exhaust system 39 has a pipe portion 50p provided so as to extend along the brake pedal 24 in the front-rear direction of the vehicle, and at least a portion of the exhaust gas sensor 46 provided in the pipe portion 50p is located inside the brake pedal 24 in the width direction of the vehicle and is covered by the brake pedal 24.
