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 shaft 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 wheel for cracks, scoring and deformation; change the wheel if damaged.
Insert the shaft 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.
Removal of the gear selector lever
Unscrew and remove the fixing screws (18) and (20) of the complete gear
selector lever (21) and collect the spacer (19).
Remove the gearchange mechanism complete with the shaft, spring, and stop plate.
Important
Visually inspect the gear selector claw (14) for wear, particularly aroun ...

Explanation of the function of the ride-by-wire system
Mechanism
Via metal cables, the throttle grip operates a roller mounted on one end of a
spindle located near the horizontal cylinder
throttle valve spindle.
The aps sensor, which measures the position of the throttle grip itself, is
mounted on the opposite end of this spindle.
