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

–
Check the front and rear tires for cuts, run-in objects, and other damage.
» If the tires have cuts, run-in objects, or other damage:
–
Change the tires.
–
Check the tread depth.
Info
Adhere to the legally required minimum tread depth.
Minimum tread depth
≥
2 mm (
≥
0.08 in)
» If the tread depth is less than the minimum tread depth:
–
Change the tires.
H01144-01
–
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.
» If the tires are 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.
400695-01
–
Remove the protection cap.
–
Check the tire air pressure when the tires are cold.
Tire air pressure off road
Front
1.0 bar (15 psi)
Rear
1.0 bar (15 psi)
» If the tire pressure does not meet specifications:
–
Correct the tire pressure.
–
Mount the protection cap.

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.)
