Yamaha Front Wheel Sensor – XMAX 300

The Yamaha XMAX 300 Front Wheel Sensor (B74‑H5970‑01) is a genuine replacement sensor that plays a critical role in the scooter’s safety systems, particularly ABS (Anti‑Lock Braking System) and traction control. Mounted near the front wheel hub, this sensor detects the rotational speed of the front wheel and sends that information to the ABS control unit. The ABS system uses this data to monitor wheel slip and adjust brake pressure to prevent wheel lock‑up during hard braking, improving stability and stopping performance.

Manufactured to Yamaha’s original specifications, the front wheel sensor ensures precise and consistent signal transmission under all riding conditions. It is designed to withstand vibration, moisture, heat, and road debris typical of everyday use. A damaged, worn, or malfunctioning sensor can trigger warning lights on the dashboard, compromise braking system performance, or disable ABS functionality. Installing this replacement sensor restores proper wheel speed detection, helping maintain safe braking response, system reliability, and compliance with the scooter’s designed safety features.
