Dismounting and mounting the front wheel

To remove the front wheel, jack the motorcycle up on its frame so that the
front wheel no longer touches the ground.
Loosen the collar screw [1] and the clamping screws [2] on both fork leg axle
passages.
Unscrew the collar screw approx 8 turns, press on the collar screw with your
hand to push the wheel spindle out of the fork leg axle passage and remove
the collar screw. Hold the front wheel while you pull out the wheel spindle.
Lift the front wheel off the fork.

To install the front wheel, lift it into the fork, position and mount the axle
shaft [3]. Mount the collar nut [1], tighten the clamping screws [2] on the
right fork leg axle passage to prevent the axle shaft from turning and tighten
2
the collar nut to 40 Nm (30ft.lb).
Loosen the clamp screws on the right fork leg. Take the motorcycle down from
its stand. Press the front wheel brakes and push down on the fork a few times
vigorously so that the fork legs come into alignment.
Only after this has been accomplished, tighten the clamp screws on both fork
legs with 15 Nm(7 ft. lbs).

– Do not operate the hand brake when the front 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 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 behavior 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.
