7.2 Fork and headset
The headset is the bearing assembly that allows the fork, stem and handlebar to turn.
CHECKS TO BE MADE:
Inspect the headset on your scooter once a month and check it is neither too tight
nor too loose. If it is, do not use the scooter and take it to a specialized repair shop.
Checking for looseness when adjusting the headset: stand behind the handlebar with both feet on the ground.
Press the front brake down while moving the scooter backwards and forwards. Look, listen, and feel to see if
the front headset is loose.
Checking for tightness when adjusting the headset: stand behind the handlebar with both feet on the ground.
Turn the fork and the handlebar from right to left and vice versa. Look, listen, and feel to see if the front headset
is so tight that it makes a noise when it is turned or sticks at certain points.
The headset should be lubricated once a year. This job requires specialist tools and knowledge and should only
be carried out by a specialized repair shop.
The suspension forks need to be lubricated on a regular basis to ensure they operate smoothly and have a long
useful life. READ INSTRUCTIONS AND THE INFORMATION IN THE ATTACHED SUPPLIER’S MANUAL.
IMPORTANT:
Changes in the fork or the variation of the length of the suspension may affect the scooter’s
ability to turn, create very high tensions or cause fatigue effects on the scooter.
7.3 The handlebar and stem.
Make sure the position you adopt on the bike is as ergonomic as possible.
CHECKS TO BE MADE:
Check that all the bolts are properly tightened. Every month you check that the
stem is properly aligned with the front wheel. Check the coupling between the stem and the handlebar any try
to move it in relation to the front.
