Tires, air pressure
Tire type, tire condition, and air pressure level affect the way your motorcy-
cle rides, and they must therefore be checked whenever you are getting
ready to go anywhere on your motorcycle.
Tire size can be found in the technical specifications
Tire condition has to be checked every time you want to ride your motorcy-
cle. Before leaving, check tires for punctures and nails or other sharp
objects that might have become embedded in them.
Tire pressure should be checked regularly on a “cold” tire. Proper pressure
(1.0 bar) ensures optimum driving comfort and extends the life of your tires.

Checking spoke tension
The correct spoke tension is very important for the stability of the wheels
and thus for riding safety. A loose spoke causes the wheel to become
unbalanced and before long other spokes will have come loose. Check
spoke tension, especially on a new motorcycle, at regular intervals. For
checking, tap on each spoke with the blade of a screwdriver (see photo). A
clear tone must be the result. Dull tones are indicators of loose spokes. If
necessary, have the spokes retightened and the wheel centered by a KTM
dealer.
