Tires, air pressure

Tire type, tire condition, and air pressure level affect the way your motor-cycle
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
rear
TIRES COULD HAVE ADVERSE EFFECTS ON THE WAY YOUR MOTORCYCLE
BEHAVES.
1,0 bar
– FRONT AND REAR WHEELS MAY ONLY BE FITTED WITH TIRES HAVING THE

2,0 bar
– FOR YOUR OWN SAFETY REPLACE DAMAGED TIRES IMMEDIATELY.
– WORN TIRES CAN HAVE A NEGATIVE EFFECT ON HOW YOUR MOTORCYCLE
PERFORMS, ESPECIALLY ON WET SURFACES.
– IF AIR PRESSURE IS TOO LOW, ABNORMAL WEAR AND OVERHEATING OF THE
TIRE CAN RESULT.

Check/set distance of the magnetic sensor

The distance between magnet [2] and sensor [1] must be 2-4 mm
(0,08-0,16 in), otherwise malfunctions on the speedometer might occur.
This distance can be corrected by screwing in or off the sensor [1].
