FRONT WHEEL
ECA14140
NOTICE
Before tightening the wheel axle nut, push
down hard on the handlebar(s) several times
and check if the front fork rebounds smooth-
ly.
4. Install:
• Front wheel sensor
ECA21020
NOTICE
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.
TIP
• When installing the front wheel sensor, check
the wheel sensor lead for twists.
• To route the front wheel sensor lead, refer to
“CABLE ROUTING” on page 2-38.
5. Measure:
• Distance “a”
(between the front wheel sensor rotor “1” and
front wheel sensor “2”)
Out of specification  Check the wheel bear-
ing for looseness, and the front wheel sensor
and sensor rotor installation conditions (war-
page caused by overtorque, wrong installa-
tion direction, rotor decentering, LOCTITE®
on the mounting surface of the rotor, defor-
mation caused by an impact during service
and caught foreign materials). If there is any
defective part, repair or replace the defective
part.
TIP
Measure the distance between the front wheel
sensor rotor and front wheel sensor in several
places in one rotation of the front wheel. Do not
turn the front wheel while the feeler gauge is in-
stalled. This may damage the front wheel sensor
rotor and the front wheel sensor.
6. Install:
• Front brake caliper
• Front brake hose holder
