• Front wheel axle pinch bolt
1. Insert the front wheel axle from the right side and tighten it with the flange bolt from the left
side to 91 Nm (9.1 m·kg, 65.8 ft·lb).
2. In the order from the pinch bolt “2”
→
pinch bolt “1”

pinch bolt “2”, tighten each bolt to 21 Nm
(2.1 m·kg, 15 ft·lb) without performing temporary tightening.
3. Check that the end face of the axle head and the end face of the fork side are flush-mounted.
If they are out of alignment, make sure to fit them by adding the external force by hand or with
a plastic hammer, etc.
If the end face of the axle is not parallel to the end face of the fork, align them so that one point
of the axle circumference is positioned on the end face of the fork.
At this stage, it can be accepted if the end face of the axle becomes partially concave to the
end face of the fork.
