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.
13.7

Checking spoke tension

Warning
Danger of accidents Incorrectly tensioned spokes impair the handling characteristic and result in secondary 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.)
» If the tread depth is less than the minimum tread depth:
–
Change the tires.
–
Check the tire age.
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 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.

–
Strike each spoke briefly using a screwdriver blade.
Info
The frequency of the sound depends on the spoke length and spoke diame-
ter.
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 differs:

Check the spoke torque.
