Tires, air pressure
Tire type, tire condition, and air pressure level affect the way your motor-
cycle 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 and in their homolo-
gation certificate
Tire condition has to be checked every time you want to ride your
motorcycle. Before leaving, check tires for punctures and nails or other
sharp objects that might have become embedded in them.
Refer to the specific regulations in your country for minimum tire tread
requirements. We recommend you replace the tires at the latest when
the tread is down to 2 mm (0.08 in).
Tire pressure should be checked regularly on a “cold” tire. Proper pres-
sure 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 unba-
lanced and before long other spokes will have come loose. Check spoke
tension, especially on a new motorcycle, in 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.

Replacing the battery of the digital speedometer
After approx. 2 years, the battery of the digital speedometer will be empty
and must be replaced. For this purpose, the speedometer must be
dismounted.
Remove headlight mask, and pull speedometer illumination system

of the speedometer housing.
Use a screwdriver to lever the blue speedometer glass
2 downward and
out of the speedometer housing
3. The two noses A must be disengaged
from the speedometer housing. Remove screws 4, and take speedometer
out of housing.
Before you remove the battery, do not forget to write down the following
data:
total kilometer reading (DST)
wheel circumference (WS) (KTM standard tires = 2205 mm)
Remove the battery cover on the back of the speedometer and detach the
batteries. The new batteries must be inserted with the plus pole on top.
Make sure that the seal ring has the right position on the cover when
mounting the battery cover.
Now total mileage, wheel circumference and time have to be entered.
To mount the speedometer, proceed by following the reverse order of the
above procedure.
