Checking spoke tension
The correct spoke tension is very important for the stability of the wheels and thus for rid-
ing safety. A loose spoke causes the wheel to become unbalanced and before long other
spokes will have come loose. Check spoke tension, especially on a new motorcycle, in reg-
ular intervals. For checking, tap on each spoke with the blade of a screw driver (see illus-
tration). A clear tone must be the result. Dull tones indicate loose spokes. If necessary, have
the spokes retightened and the wheel centered by a KTM dealer.
– If you continue to drive with loose spokes, the spokes can tear and lead to an instable
handling performance. Torn spokes can damage the air hose. The loss of air can easily
cause the motorcycle to go out of control.
– Excessively tensioned spokes may rupture due to local overloading. The spokes must be
tensioned to 5 Nm ± 1 Nm.
