How to change the handlebar position

The handlebar position can be readjusted by 22 mm. Thus, you can put the
handlebar in the position that is the most convenient for you. The upper triple
clamp [1] includes 2 bores arranged at a distance of 15 mm (0.6 in) from
one another. The bores at the handlebar support [2] are offset from the center
by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in
4 different positions.
For this purpose, remove screws [3] of the handlebar clamps and screws [4]
of the handlebar support. Position the handlebar support, and tighten screws
3
[4] to 40 Nm (30 ft.lbs). Mount the handlebar and handlebar clamps, and
tighten screws [3] to 20 Nm (15 ft.lbs). The gap between the handlebar support
and the handlebar clamps should be the same size in the front and in the
rear.
