Info
The tire date of manufacture is usually contained in the
tire label and is indicated by the last four digits of the
DOT
number. The first two digits indicate the week of
manufacture and the last two digits the year of manu-
facture.
KTM recommends that the tires be changed after 5
years at the latest, regardless of the actual state of
wear.
» If the tires are more than 5 years old:
–
Change the tires.

13.7
Checking spoke tension
Warning
Danger of accidents
Incorrectly tensioned spokes impair the handling characteristic and result in sec-
ondary damage.
The spokes break due to being overloaded if they are too tightly tensioned. If the tension in the spokes
is too low, then lateral and radial run-out will form in the wheel. Other spokes will become looser as a
result.
–
Check spoke tension regularly, and in particular on a new vehicle. (Your authorized KTM workshop will
be glad to help.)

–
Strike each spoke briefly using a screwdriver blade.
Info
The frequency of the sound depends on the spoke
length and spoke diameter.
If you hear different tone frequencies from different
spokes of equal length and diameter, this is an indica-
tion of different spoke tensions.
You should hear a high note.
