– 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 FRONT WHEEL, KEEP OPERATING THE HAND BRAKE
UNTIL THE PRESSURE POINT RETURNS.
– IT IS VERY IMPORTANT TO KEEP THE BRAKE DISK FREE FROM OIL AND FATTY
MATTERS, OTHERWISE THE BRAKING EFFECT WOULD BE STRONGLY REDUCED.
Dismounting and mounting the rear wheel
Jack the motorcycle up on its frame so that the rear wheel no longer
touches the ground.
Loosen the collar nut [1], remove chain tensioner [2], hold the rear wheel and
pull out the wheel spindle [3] until the rear wheel is free but the brake caliper
support is still held.
Push the rear wheel as far forward as possible, take the chain from the chain
wheel and carefully take the rear wheel out of the swingarm.
– DO NOT OPERATE THE REAR BRAKE WHEN THE REAR WHEEL HAS BEEN
DISMOUNTED.
– 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.
The rear wheel is remounted in the reverse order. Before tightening the col-
lar nut to 80 Nm, push the rear wheel forwards so that the chain tensioners
lie on the tension screws.
– IF YOU DON’T HAPPEN TO HAVE A TORQUE WRENCH AT HAND, MAKE SURE

– 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 COLLAR NUT WITH THE REQUIRED TORQUE. A LOOSE WHEEL
SPINDLE MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE.
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 5 NM.
