6. Lower the front wheel so that it is on the
ground.
7. Tighten:
• Front wheel axle bolt
Front wheel axle bolt
91 Nm (9.1 m·kgf, 66 ft·lbf)
• Front wheel axle pinch bolt
Refer to "CHASSIS TIGHTENING
TORQUES" on page 2-20.
Front wheel axle pinch bolt
21 Nm (2.1 m·kgf, 15 ft·lbf)

Before tightening the wheel axle, push
down hard on the handlebar(s) several
times and check if the front fork rebounds
smoothly.
8. Install:
• Front speed sensor
Front speed sensor bolt
7 Nm (0.7 m·kgf, 5.1 ft·lbf)

Make sure there are no foreign materials in
the front speed sensor rotor and front
speed sensor. Foreign materials cause
damage to the front speed sensor rotor and
front speed sensor.
9. Measure:
• Distance
(between the front speed sensor rotor
and front speed sensor)
Out of specification → Check the wheel
bearing for looseness, and the front
speed sensor and sensor rotor installa-
tion conditions (warpage caused by over-
torque, wrong installation direction, rotor
decentering, LOCTITE® on the mount-
ing surface of the rotor, deformation
caused by an impact during service and
caught foreign materials). If there is any
defective part, repair or replace the
defective part.
Distance (between the front
speed sensor rotor and front
speed sensor)
1.0–2.2 mm (0.04–0.09 in)

TIP
• Before measuring the distance between the
front speed sensor rotor and front speed
sensor, remove the brake caliper.
• Measure the distance between the front
speed sensor rotor and front speed sensor in
several places in one rotation of the front
wheel. Do not turn the front wheel while the
thickness gauge is installed. This may dam-
age the front speed sensor rotor and the
front speed sensor.

• Front brake calipers
• Front brake hose holders
Front brake caliper bolt

WARNING
Proper brake hose routing is essential to
insure safe vehicle operation. Refer to
"CABLE ROUTING" on page 2-49.

To route the front speed sensor lead, refer
to "CABLE ROUTING" on page 2-49.
TIP
