Dismounting and remounting the rear wheel *
Place the back of the motorcycle on a motorcycle stand (available as an acces-
sory), lifting the rear wheel entirely off the ground.
Unscrew the collar nut [1], remove the chain tensioner [2], hold the rear wheel
while you pull out the wheel spindle [3]. Push the rear wheel forward as far
as possible and remove the chain from the rear sprocket. Carefully take the
rear wheel off the swing arm.
– DO NOT OPERATE THE REAR BRAKE WHEN THE REAR WHEEL HAS BEEN DIS-
MOUNTED.
– ALWAYS PLACE THE WHEEL ON THE GROUND WITH THE BRAKE DISC POINT-
ING UPWARDS. OTHERWISE THE BRAKE DISC MAY 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 (MOTOREX
LONG THERM 2000) TO PREVENT THE THREAD FROM JAMMING.
Before remounting the rear wheel, clean and grease the bearing surface of
the bushings [5] and the shaft seal ring [6].
The rear wheel is remounted in the reverse order. Make sure the chain ten-
sioners [4] are mounted in the same way on the left and right. The marks on
the chain tensioners must be in the same position on the left and right in
relation to the reference marks [A]. Before you tighten the collar nut to
90 Nm, press the rear wheel towards the front to allow the chain tensioner to
rest against the clamping screws.
– 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 WHEEL SPINDLE MAY LEAD TO AN UNSTABLE DRIV-
ING BEHAVIOR OF YOUR MOTORCYCLE.
– AFTER MOUNTING THE REAR WHEEL, KEEP OPERATING THE FOOTBRAKE
UNTIL THE PRESSURE POINT RETURNS.
– IT IS VERY IMPORTANT TO KEEP THE BRAKE DISK FREE FROM OIL AND
GREASE, OTHERWISE THE BRAKING EFFECT WOULD BE STRONGLY REDUCED.
