An exhaust gas sensor for a motorcycle that is protected against sprayed mud and flying stones without a dedicated protective cover. The exhaust gas sensor is inclined inward to the inside of the motorcycle body relative to a vertical line passing through a sensor attachment part formed on an upper part of an exhaust pipe on the inside of a main frame. The exhaust gas sensor is positioned above a pivot shaft of a seat cushion, in front of a shock absorber, and in front of a mud flap in front of a rear wheel. The exhaust gas sensor is protected by the exhaust pipe at a lower portion of the sensor. A front portion of the exhaust gas sensor is surrounded and protected by parts around the handlebars and parts around the engine. Both sides of the exhaust gas sensor are surrounded and protected by the main frame, the engine, the parts around the engine, and various parts engaging the shock absorber. A rear portion of the exhaust gas sensor is protected by the mud flap.
