Important
Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.
Removal of the front wheel
Support the bike so that the front wheel is raised from the ground.
Remove the front brake calliper (B) by unscrewing the two screws (A) securing the calliper to the fork leg; do not disconnect the calliper from the hose.
Warning
Do not operate the brake lever when the callipers are removed. This can cause the brake pistons to be expelled.
 
Loosen and remove the nut (1) on left side of the axle.
Recover the washer (2).
Loosen the wheel shaft screws (8) on the fork legs.
Working from the left-hand side, use a plastic mallet to drive the axle (10) out from the opposite side and remove it.
Remove the wheel and recover the spacers (3) and (9).
Working from both sides, remove the oil sealing ring (4).
Overhauling the front wheel
Wheel bearings
Before checking the dimensions, check the wear on wheel bearings. Check for wear by hand after cleaning and degreasing the bearings in their seats.
Turn the inner race.
Check the amount of radial and axial play. Excessive play will cause vibration and make the bike unstable.
To remove the bearings (5) and the sealing rings (4) from the wheel hub follow the instructions below.
Position a drift (A) against the inner race of the bearing (5).
Tap with a hammer until knocking out the bearing (5).
Apply the drift at different points to keep the bearing square during removal.
Important
Once removed, the used bearings and sealing rings must not be refitted.
Before fitting new bearings, check that the housing is clean and free from scoring and damage.
 
Grease the bearing seat and then push the new bearing into its seat.
Using a tubular drift (B) that only bears on the outer race of the bearing, drive the bearing (5) fully into its seat.
Use the same method to install the sealing rings (4).
Ensure that spacer (7) is fitted between the two wheel bearings.
Note
Wheels must be rebalanced after repair, maintenance and overhaul operations.
Inspecting the wheel axle
Check the wheel axle for straightness.
Turn the pin on a reference surface and measure maximum distortion using a feeler gauge (see Sect. 3 - 1.1, Front wheel).
Overhauling the wheel
After you have checked the bearings, check the rim as follows.
Visually inspect the rim for cracks, scoring and deformation: change the wheel if damaged.
Insert the axle in the wheel and mount it on two fixed reference blocks.
Using a dial gauge, measure rim run-out and out-of-round relative to the pin axle (see Sect. 3 - 1.1, Front wheel).
If the values measured are not within the tolerance limits, renew the wheel.
Refitting the front wheel
When all the necessary inspections have been completed, refit the wheel as follows.
Lubricate and fit the spacers (3) and (9) to the sealing rings on the sides of the wheel hub.
Install the complete wheel between the fork legs.
Lubricate the shank and thread of the wheel axle (10).
Take the pin (10) fully into the wheel hub.
Fit the washer (2) on the end of the axle.
Grease the thread and the underside of the head of the axle lock nut (1), then screw it on.
Tighten the nut (1) to the torque of 63 Nm ± 5% (Sect. 3 - 3, Frame torque settings).
Grease the threads and undersides of the heads of screws (A).
Screw in the two screws (A) securing the brake calliper (B).
Operate the front brake lever two or three times.
Hold the lever pulled towards the handgrip and simultaneously tighten the screws (A) to a torque of 45 Nm ± 5%(Sect. 3 - 3, Frame torque settings).
Before tightening the screws (8), lower the motorcycle to the ground and push up and down the handlebars to load the suspen­sion; so the fork legs will become properly seated onto the wheel axle.
Lubricate the screws (8) (1200 S ABS).
Tighten the screws (8) to the torque of 10 Nm ± 5% (1200 ABS) / 19 Nm ± 5% (1200 S ABS) (Sect. 3 - 3, Frame torque settings) following the sequence 1-2-1.
