Info
The tire's date of manufacture is usually part of the tire markings and is
indicated by the last four digits of the
DOT
marking. The first two digits indi-
cate the week of manufacture and the last two digits the year of manufac-
ture.
KTM recommends that the tires be changed after 5 years at the latest,
regardless of the actual state of wear.
» If the tire is older than five years:
–
Change the tire.

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.

–
Tap each spoke with a screwdriver.
Info
The sound frequency depends on the length and thickness of the spoke.
If there are different sound frequencies in spokes with the same length and
thickness, this indicates different spoke tensions.
You should hear a high note.

–
Correct the spoke tension.
