Checking the rear wheel sensor and sensor rotor
1. Check:
- Rear wheel sensor
Cracks/bends/distortion → Replace.
Iron powder/dust → Clean.
2. Check:
- Rear wheel sensor rotor. Cracks/damage → Replace.
Installing the rear wheel sensor
1. Install:
- Sensor rotor «1»
Sensor rotor bolt: 6 Nm (0.6 m·kg, 4.3 ft·lb).

2. Install:
- Rear wheel
Refer to «Installing the rear wheel».
Caution! Make sure there are no foreign materials in the wheel hub. Foreign materials cause damage to the inner sensor rotor and wheel sensor.
3. Install:
- Rear wheel sensor «2»
- Rear wheel sensor protector
- Rear wheel sensor lead stay
Rear wheel sensor bolt: 7 Nm (0.7 m·kg, 5.1 ft·lb).
Rear wheel sensor protector bolt: 7 Nm (0.7 m·kg, 5.1 ft·lb).
Rear wheel sensor lead stay bolt: 7 Nm (0.7 m·kg, 5.1 ft·lb).
Note: When installing the rear wheel sensor, check the rear wheel sensor lead for twists and the sensor electrode for foreign materials.
Caution! To route the rear wheel sensor lead, refer to «Cable routing».
