Checking and adjusting the steering head bearing (50 SX
SENIOR) *
The steering head bearing should be checked regularly for play. To check,
support the motorcycle frame and lift the front wheel off the ground. Now
try to move the fork back and forth – you should not feel any play. To
adjust, loosen both clamping screws
1 on the upper triple clamp and loosen
the steering head screw 2 by a few turns. Lift the triple clamp slightly and
turn the adjusting nut 3 until hardly any play is left. Never tighten the
adjusting nut since you might damage the bearing. Tighten the steering
head screw to a torque of 10 Nm and the 2 clamping screws to 15 Nm.

How to change the handlebar position
The handlebar position can be readjusted by 22 mm (0.9 in). The upper
triple clamp
4 includes 2 bores arranged at a distance of 15 mm (0.6 in)
from one another. The bores at the handlebar support 5 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 6 of the handlebar clamps and screws 7
of the handlebar support. Position handlebar support, and tighten screws 7
to 40 Nm. Mount handlebar and handlebar clamps, and tighten screws 6
to 20 Nm. The gap between the handlebar support and handlebar clamps
should be the same size in the front and in the rear.
