Checking the tire condition
Info
Only mount tires approved and/or recommended by KTM.
Other tires could have a negative effect on riding behavior.
The type, condition and air pressure of the tires all have an important impact on the riding behavior of the motorcycle.
The tires mounted on the front and rear wheels must have a similar profile.
Worn tires have a negative effect on riding behavior, especially on wet surfaces.

–
Examine the front and rear tires for cuts, foreign bodies and other damage.
» If you find cuts, foreign bodies or other damage on a tire:
–
Change the tire.
–
Check the tire age.
Info
The tire manufacture date is usually included in the tire identification num-
ber and comprises the last four digits of the
DOT
code. 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 tire is older than five years:
–
Change the tire.

Checking the tire air pressure
Info
If the tire air pressure is too low, this will lead to abnormal wear and overheating of the tire.
Correct tire air pressure ensures optimal riding comfort and the maximum service life of the tire.

–
Remove the protection cap.
–
Check the tire air pressure on cold or warm tires.
Tire air pressure (cold)
Front: 10… 30 °C (50… 86 °F)
1.9 bar (28 psi)
Rear: 10… 30 °C (50… 86 °F)
1.7 bar (25 psi)
Tire air pressure (warm)
Front: 75… 85 °C (167… 185 °F)
2.1 bar (30 psi)
Rear: 75… 85 °C (167… 185 °F)
1.9 bar (28 psi)
» If the tire air pressure does not meet the specification:
–
Correct the tire air pressure.
–
Mount the protection cap.

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.
