Yamaha Xmax 300 ABS Motor (B74-85930-19)

The Yamaha XMAX 300 ABS Motor (Part No. B74-85930-19) is the electric actuator unit that drives the anti-lock braking system (ABS) on the XMAX 300. This motor works as part of the ABS hydraulic modulator to rapidly control brake fluid pressure for the front and rear circuits during hard braking. When wheel speed sensors detect a potential wheel lock-up, the ABS motor activates the internal pump to modulate pressure, helping maintain traction and directional control.

As an OEM-level unit, this motor is engineered to match Yamaha’s original design criteria for fit, function and durability. It precisely integrates with the ABS control module, valve body, and master cylinder system to deliver consistent modulation performance. Over time, ABS motors can wear or fail due to age, electrical stress, contamination or heat, leading to ABS warning lights, reduced system function or intermittent braking control. Replacing the worn or faulty ABS motor with this genuine-style part restores proper ABS action, improves braking safety, and ensures compliance with the factory braking system’s performance.
