brake disc to ensure it is at least thickness f).

Wear reduces the thickness of the brake disc around the area used by the
brake linings.

If the brake disc thickness is less than the specified value:
-
Change the front brake disc.
-
Change the rear brake disc.
Check the front and rear brake discs for damage, cracking, and deformation.
If the brake disc exhibits damage, cracking, or deformation:
-
Change the front brake disc.
-
Change the rear brake disc.
Danger of accidents
Incorrectly tensioned spokes impair the handling characteristic and result in secondary damage.
The spokes break due to being overloaded if they are too tightly tensioned. If the tension in the spokes is too low, then lat
eral and radial run-out will form in the wheel. Other spokes will become looser as a result.
-
Check spoke tension regularly, and in particular on a new vehicle.
Info
A loose spoke causes wheel imbalance and rapidly leads to more loose spokes.
If the spokes are too tight, they can break due to local overload.
Check the spoke tension regularly, especially on a new motorcycle.
Briefly strike each spoke with the tip of a screwdriver.

Info
I
The tone frequency depends on the length of the spoke and the spoke
diameter.
If you hear different tone frequencies from different spokes of equal length
and diameter, this is an indication of different spoke tensions.
I
You should hear a high note.
If the spoke tension varies:
-
Correct the spoke tension.
Check the spoke torque.
