Tires, air pressure
Tire type, tire condition, and air pressure level affect the way your motorcy-
cle rides and 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 the homolo-
gation certificate
Tire condition has to be checked every time you want to ride your motor-
cycle. 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.
DO NOT MOUNT TIRES WHICH HAVE NOT BEEN APPROVED BY KTM. OTHER
TIRES COULD HAVE ADVERSE EFFECTS ON THE WAY YOUR MOTORCYCLE
BEHAVES.
FRONT AND REAR WHEELS MAY ONLY BE FITTED WITH TIRES HAVING THE
SAME TREAD LAYOUT. USE HOMOLOGATED TIRES
FOR YOUR OWN SAFETY REPLACE DAMAGED TIRES IMMEDIATELY.
WORN TIRES CAN HAVE A NEGATIVE EFFECT ON HOW YOUR MOTORCYCLE PER-
FORMS, ESPECIALLY ON WET SURFACES
IF AIR PRESSURE IS TOO LOW, ABNORMAL WEAR AND OVERHEATING OF THE
TIRE CAN RESULT
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.
SPOKES CAN TEAR IF YOU CONTINUE TO RIDE WITH THEM LOOSE. THIS MAY
LEAD TO AN UNSTABLE HANDLING OF YOUR MOTORCYCLE.
EXCESSIVELY TENSIONED SPOKES MAY RUPTURE DUE TO LOCAL OVERLOAD-
ING.THE SPOKES MUST BE TENSIONED TO 5 NM.
Replacing the battery of the digital speedometer
Remove the headlight mask and disassemble the electronic speedometer.
Remove the screw connection [1], insert the battery (type Duracell CR 2430)
with the writing facing up and reinstall the screw connection.
