Installation:
1. Reverse the removal procedure. Make
sure that the lug (1) on the fork leg is
located in the slot (2) in the brake panel.
Be sure to tighten the front axle nut to:
46 N·m (4.8 kgf·m, 35 lbf·ft)
2. Check front brake adjustment.
3. After installing the wheel, apply the
brake several times and then check if
the wheel rotates freely. Recheck the
wheel if the brake drags or if the wheel
does not rotate freely.
If a torque wrench is not used for
installation, see your dealer as soon as
possible to verify proper assembly.
Improper assembly may lead to loss of
braking capacity.
