Yamaha YA125 Motorcycle Oxygen Sensor 2DP-H592A-00 Direct replacement for original factory part

Yamaha YA125 motorcycle oxygen sensor (OEM number: 2DP-H592A-00) directly replaces the OEM part, installed in the front section of the exhaust pipe; monitors real-time oxygen content in exhaust and feeds signal to the ECU to precisely control air-fuel ratio, ensuring efficient combustion and compliant emissions. Compatible with 2BM-H592A-10, 2DP-H592A-10 and OS028222030; perfectly fits YA125 model. Installation difficulty is moderate; estimated labor about 30 minutes; take care not to damage threads during removal. If idle is unstable, acceleration is weak, fuel consumption rises noticeably, or the engine warning light is on, sensor performance has degraded; timely replacement is recommended.
