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 five years old:
–
Change the tires.
13.6 Checking tire pressure
Info
Low tire pressure leads to abnormal wear and overheating of the tire.
Correct tire pressure ensures optimal riding comfort and maximum tire service life.

… 185 °F) 2.1 bar (30 psi)
rear: 75 … 85 °C (167

Correct the tire pressure.

Mount the protection cap.
13.7 Checking the 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.)
