Checking spoke tension
Warning
Danger of accidents ಘUnstable riding behavior due to loose spokes.
ದ If you ride with loose spokes, the spokes can break. Have the spoke tension corrected in an authorized KTM workshop.
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.
