Removing and installing the rear wheel

Jack the motorcycle up by the frame.
Remove the hexagon nut [1] of the wheel spindle together with the washer
[2] and remove the chain adjuster [3].
Hold the rear wheel and pull out the wheel spindle.
Turn the rear wheel forwards and take the chain off the rear sprocket.
Pull the rear wheel backwards.
To install the rear wheel reverse the procedure described above.
1
Slightly grease the wheel spindle.
Before tightening the hexagon nut [1] make sure that the chain adjusters [3]
are properly resting against the tensioning screws. Additionally, make sure
that the rear wheel is properly aligned with the front wheel.
Mount the hexagon nut and tighten to 40 Nm.
– DO NOT OPERATE THE REAR BRAKE WHEN THE REAR WHEEL HAS BEEN DIS-
MOUNTED.
– MAKE SURE THE BRAKE DISC IS ALWAYS ON TOP WHEN YOU LAY DOWN THE
WHEEL, OTHERWISE THE BRAKE DISC CAN BE DAMAGED.
– IF THE AXLE IS DISMOUNTED, CLEAN THE THREAD OF THE WHEEL SPINDLE
AND COLLAR NUT THOROUGHLY AND APPLY A NEW COAT OF GREASE TO PRE-
VENT THE THREAD FROM JAMMING.
– IF YOU DON'T HAPPEN TO HAVE A TORQUE WRENCH AT HAND, MAKE SURE
YOU HAVE THE TIGHTENING TORQUE CORRECTED BY A KTM DEALER AS SOON
AS POSSIBLE. A LOOSE AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAV-
IOR OF YOUR MOTORCYCLE.
– AFTER MOUNTING THE REAR WHEEL, KEEP OPERATING THE REAR BRAKE UNTIL
THE PRESSURE POINT RETURNS.
– IT IS VERY IMPORTANT TO KEEP THE BRAKE DISK FREE FROM OIL AND FATTY
MATTERS, EITHERWISE THE BRAKING EFFECTS WOULD BE STRONGLY REDUCED.
– TIGHTEN THE HEXAGON NUT TO THE REQUIRED TORQUE. A LOOSE WHEEL
SPINDLE MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE.

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 motorcycle.
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.
– DAMAGED TIRES MUST BE REPLACED IMMEDIATELY TO PROTECT YOUR
YOUNGSTER.
– WORN TIRES CAN HAVE A NEGATIVE EFFECT ON HOW THE MOTORCYCLE PER-
FORMS, ESPECIALLY ON WET SURFACES
– TIRE PRESSURE BELOW THE NORMAL LEVEL WILL LEAD TO PREMATURE TIRE
WEAR.

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, espe-
cially 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 3-4 NM.
