Checking spoke tension
Warning
Danger of accidents
Instable handling due to incorrect spoke tension.
–
Ensure that the spoke tension is correct. (Your authorized KTM workshop will be glad to help.)
Info
A loose spoke can cause wheel imbalance, which leads to more loose spokes in a short time.
If the spokes are too tight, they can break due to local overload.
Check the spoke tension regularly, especially on a new motorcycle.
