EXHAUST GAS SENSOR ARRANGEMENT STRUCTURE FOR MOTORCYCLE

摘要

An exhaust gas sensor arrangement structure for a motorcycle includes a vehicle body frame, an internal combustion engine suspended on the vehicle body frame between front and rear wheels and exhaust pipes extending toward a rear side in the longitudinal direction of a vehicle from a front side of the internal combustion engine in the longitudinal direction of the vehicle in a state where the exhaust pipes extend below the internal combustion engine. Exhaust gas sensors are arranged on upper halves of the exhaust pipes arranged between the internal combustion engine and the bottom frame portions as viewed from a front side in the longitudinal direction of the vehicle in a state where the exhaust gas sensors are sandwiched between the internal combustion engine and the bottom frame portions as viewed from a front side in the longitudinal direction of the vehicle.
