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

Checking the tire air pressure
Info
Low tire air pressure leads to abnormal wear and overheating of the tire.
Correct tire air pressure ensures optimal riding comfort and maximum tire service life.

Checking the 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 causes wheel imbalance and rapidly leads to more loose spokes.
If the spokes are too tight, they can break due to local overload.
Check the spoke tension regularly, especially on a new motorcycle.

–
Briefly strike each spoke with the tip of a screwdriver.
Info
The tone frequency depends on the length of the spoke and the spoke diam-
eter.
If you hear different tone frequencies from different spokes of equal length
and diameter, this is an indication of different spoke tensions.
You should hear a high note.
» If the spoke tension varies:
–
Correct the spoke tension.
–
Check the spoke torque.
