Checking spoke tension

The correct spoke tension is very important for the stability of the wheels
and thus for riding safety. A loose spoke causes the wheel to become unba-
lanced and before long other spokes will have come loose. Check spoke
tension, especially on a new motorcycle, in regular intervals. For checking,
tap on each spoke with the blade of a screwdriver (see photo). A clear tone
must be the result. Dull tones are indicators of loose spokes. If necessary,
have the spokes retightened and the wheel centered by a KTM dealer.
