- Remove the front wheel rotation sensor [A] from the front fork.
- Remove the rear wheel rotation sensor [B] from the caliper bracket.
- Visually inspect the wheel rotation sensors.
Replace the wheel rotation sensor if it is cracked, bent, or otherwise damaged.

Wheel Rotation Sensor Air Gap Inspection
- Raise the front/rear wheel off the ground (see Front/Rear Wheel Removal in the Wheels/Tires chapter).
- Measure the air gap between the sensor and sensor rotor at several points by turning the wheel slowly.
- Thickness Gauge [A]
Air Gap
Standard:
- Front 1 mm (0.04 in.)
- Rear 1 mm (0.04 in.)

Note: The sensor air gap cannot be adjusted.
If the airgap is not within the specification, inspect the hub bearing (See Hub Bearing Inspection in the Wheels/Tires chapter), sensor installation condition and sensor (See Wheel Rotation Sensor Inspection).

Wheel Rotation Sensor Rotor Inspection
- Remove the front/rear brake discs (See Brake Disc Removal).
- Visually inspect the wheel rotation sensor rotor.
If the rotor is deformed or damaged (chipped teeth [A]), replace the sensor rotor with the brake disc.
If there is iron or other magnetic deposits [B], remove the deposits.
