Dismounting and mounting the front wheel (LC4 Enduro)
To remove the front wheel, jack the motorcycle up on its frame so that the
front wheel no longer touches the ground.
Loosen both clamp screws [2] on the left fork leg. Then loosen the collar nuts
[1] before loosening the clamp screws [2] on the right fork leg.
Hold the front wheel and withdraw the wheel spindle [3].
Note: The wheel spindle can be withdrawn more easily by turning it moder-
ately with a 6 mm (0.24 in) ALLAN/IMBUS key while pulling.
Carefully remove the front wheel from the fork.
– DO NOT OPERATE THE HAND BRAKE WHEN THE FRONT WHEEL HAS BEEN
DISMOUNTED.
– ALWAYS PLACE THE WHEEL ON THE GROUND WITH THE BRAKE DISC POINT-
ING UPWARDS. OTHERWISE THE BRAKE DISC MAY BE DAMAGED.
To install the front wheel, lift it into the fork, position and mount the axle
shaft. 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 the
collar nut to 40 Nm.
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.
– 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, EITHERWISE THE BRAKING EFFECTS WOULD BE STRONGLY REDUCED.
Dismounting and mounting the front wheel (LC4 Supermoto)
The front wheel of the Supermoto is essentially removed in the same man-
ner as the front wheel of the LC4. However, the brake caliper has first to be
removed. To remove the front brake caliper, remove both screws [4] and pull
the caliper backwards from the brake disc.
After mounting the front wheel, slide the brake caliper to the brake disc. Remove
the grease from the threads of both screws [4] and apply Loctite 243. Tighten
the screws with 40 Nm.
THE SCREWS [4] MUST BE SECURED WITH LOCTITE 243.
