There is very little play when adjusting the headset. The bearings can easily become
blocked or damaged.
Special tools are required to adjust headsets.
x Refer to and follow information from the headset manufacturer.
x If you lack the necessary expertise and the tools required to adjust the headset,
contact your dealer.
Excessive tightness can damage the headset and block the steering
movement, which negatively affects handling characteristics.
