Removing the seat

Turn the quick-release device approximately 180° counterclockwise, lift the
rear portion of the seat and pull the seat off backwards.
When mounting the seat ensure that the hook engages at the tank.
Checking and adjusting the steering head bearing (50 SX
JUNIOR) *
The steering head bearing should be checked regularly for play. For this
purpose, jack up the motorcycle by the frame so that the front wheel is in
the air. Now try to move the fork forward and backward. There should be
no clearance. For readjustment, release the two clamp screws
2 of the top
triple clamp and the counternut 3 . Turn the adjusting nut 4 until almost
no play is left. Do not tighten the adjusting nut! Tightening the adjusting
nut can damage the bearings! Keep in mind that tightening the counternut
3 reduces the play of the bearing. Slightly tap the top triple clamp with a
rubber hammer to prevent jamming. Then tighten the 2 clamp screws with
15 Nm.
