2016-2018本田先锋摩托车速度传感器37700-KZR-601(90224120)，原厂OEM直替

This speed sensor directly replaces original numbers 37700-KZR-601 and 90224120, with wide compatibility and a precise fit. Its function is to monitor transmission output shaft speed and send signals to the ECU to calibrate shifting points and speedometer display. Fits 2016–2018 Honda PC motorcycle models, including CTX700, NC700 series. If you notice the speedometer fluctuating, shifting is jerky, or instrument cluster light is on, replacing with this restores accurate shifting logic and speed reading. Typical aging symptoms include sluggish power at start or erratic engine speed during cruising, indicating sensor signal is inaccurate.
