YBR125 motorcycle oil float, the installation hole position, float size and YBR125 tank fully match, directly replace the crude oil float without adjusting the installation bracket; Adopt the sliding resistance detection structure, the float with the oil level up and down synchronous feedback signal, to ensure that the instrument oil quantity display is accurate; The float is oil-resistant plastic, and the connecting rod is rust-proof metal, which is suitable for the corrosion of gasoline environment and prolongs the service life of components. The sensor is fixed to the corresponding hole position of the fuel tank, and the plug of the wire harness is directly connected to the instrument interface, which is simple and efficient to operate. The interface between the sensor base and the wiring harness is sealed to prevent gasoline leakage, dust and water vapor intrusion, and ensure signal stability.
