FRONT WHEEL

INSTALLING THE FRONT WHEEL (FRONT
BRAKE DISCS)
1. Install:
• Front brake disc
ECA19150
Replace the brake disc bolts with new ones.
Tighten the brake disc bolts in stages and in a
crisscross pattern.
2. Check:
• Front brake disc
Refer to “CHECKING THE FRONT BRAKE
DISCS” on page 4-31.
3. Lubricate:
• Oil seal lip
4. Install:
• Collar
• Front wheel
• Wheel axle
5. Tighten:
• Wheel axle
• Wheel axle pinch bolt
ECA19760
Before tightening the wheel axle, push down
hard on the handlebars several times and
check if the front fork rebounds smoothly.
Check that wheel axle end “a” is flush with front
fork surface “b” and then tighten the wheel axle
pinch bolt. If wheel axle end “a” is not flush with
surface “b”, align the ends manually or with a
plastic hammer.
6. Install:
• Front wheel sensor
NOTICE
ECA21020
Make sure there are no foreign materials in
the front wheel sensor rotor and front wheel
sensor. Foreign materials cause damage to
the front wheel sensor rotor and front wheel
sensor.
When installing the front wheel sensor, check
the wheel sensor lead for twists.
7. Measure:
• Distance “a”
(between the wheel sensor rotor “1” and
wheel sensor “2”)
Out of specification → Check the wheel bear-
ing for looseness, and the front wheel sensor
and sensor rotor installation conditions
(warpage caused by overtorque, wrong in-
stallation direction, rotor decentering, LOC-
TITE® on the mounting surface of the rotor,
deformation caused by an impact during ser-
vice and caught foreign materials). If there is
any defective part, repair or replace the de-
fective part.
