Tires, air pressure
Tire type, tire condition, and how much air pressure the tires have in them
affect the way your motorcycle rides, and they must therefore be checked when-
ever you’re getting ready to go anywhere on your motorcycle.
FOR DRIVING SAFETY AND MAXIMUM HANDLING, ONLY USE TIRES AUTHORIZED
BY KTM CORRESPONDING TO THE "ZR" SPEED INDEX (OVER 240 KPH). OTHER
TIRES CAN HAVE A NEGATIVE EFFECT ON THE MOTORCYCLE'S HANDLING (E.G.
CAN CAUSE IT TO "WOBBLE" AT HIGHER SPEEDS).
– Tire type and size can be found in the technical specifications and in the
homologation certificate
– Tire condition has to be checked every time you want to ride your motor-
cycle. Before leaving check for punctures and nails or other sharp objects
that might have become embedded in the tire.
– Refer to the specific regulations in your country for minimum tire tread
requirements. We recommend replacing 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. Adapt the air
pressure to the motorcycle's total weight. Proper pressure ensures opti-
mum 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
RIDES.
– USE TIRES OF THE SAME BRAND AND TYPE FOR THE FRONT AND REAR
WHEELS.
– 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
– NEW WHEELS HAVE A SMOOTH SURFACE, WHICH MEANS THAT THEY MUST
BE RUN IN TO ACHIEVE FULL GRIP. FOR THIS PURPOSE, RIDE THE MOTOR-
CYCLE CAREFULLY AT MODERATE SPEED DURING THE FIRST 200 KILOMETERS
(125 MILES) WITH NEW TIRES, TILTING THE VEHICLE AT DIFFERENT ANGLES
SO THAT ALL SECTIONS ARE PROPERLY ROUGHENED. TIRES WILL NOT DIS-
PLAY THEIR FULL GRIP CHARACTERISTICS UNTIL THEY ARE PROPERLY RUN IN.
– FOR REASONS OF SAFETY, IT IS RECOMMENDED TO EXCHANGE THE VALVE
INSERT WHENEVER A NEW TIRE IS MOUNTED.
Battery
The battery is located in the front spoiler in front of the engine and is main-
tenance-free. It is not necessary to check the electrolyte level or to refill water.
Simply keep the battery poles clean and slightly grease them with an acid-
free grease if necessary.
NEVER REMOVE THE CLOSING COVER [1] OTHERWISE THE BATTERY WILL BE
DAMAGED.
