Notes
The references of the elements shown below are to be found in the “Wiring diagram”, in Sect. P 1.
Electric starting system
The key components of the electric starting system are a contactor (7) and a starter motor (6) fed by the battery (8).
The engine starting strategy is managed entirely by the engine ECU (28), which monitors the following inputs:

- | Engine Stop switch on right-hand handlebar switch (1)

- | Engine starter switch on right-hand handlebar switch (1)

- | Neutral sensor (30)

- | Sidestand sensor (27)

- | Clutch microswitch (43).

When these inputs are combined in the required manner, the engine control unit (28) enables engine starting.
The table lists possible engine starting combinations.
In accordance with the status of specific engine control unit inputs and the indications given in the table, the control unit enables operation of the starter motor (ON status) when the START button is pressed.
X = generic status of neutral sensor, clutch, and sidestand.
Safety device functions table
Starter motor
Power:
700 W with 12 V power.
Direction of rotation:
counterclockwise viewed from power take-off side.
The starter motor is highly compact and reliable and therefore rarely gives any type of problem. In case of malfunction, ensure that the starter motor wiring terminal is properly tightened under the nut and shows no sign of corrosion. If the terminal is properly tightened and free from corrosion, remove the starter motor and test it under no-load conditions (no load applied to the shaft). Secure the starter motor to a test bench, making sure you do not damage the casing. Use a fully charged 12 V battery for the test. Use battery-motor connection cables which are no longer than 70 cm and with the same cross-section as the cable on the motorcycle itself. Connect the negative terminal of the battery to an unpainted area of the starter motor casing and the positive terminal to its electrical terminal. The shaft of the starter motor should rotate freely and at high speed. Take care not to short-circuit the two cables connected to the battery.
Removal of the starter motor
Remove the alternator-side crankcase cover (Sect. N 8, Removal of the alternator-side crankcase cover).
If the whole starting gear assembly needs to be renewed, remove the timing gears and the starter motor idler gear (Sect. N 9.1, Removal of the starter motor idler gear).
Disconnect the starter motor/starter contactor cable (3) (see plates in the chapter Routing of wiring on frame”, Sect. P 1).
Unscrew the retaining screws (1).
Notes
The starter motor retaining screws are assembled with threadlocker.
Slide out the starter motor and gasket (2).
Refitting the starter motor
Inspect the condition of the gasket (2) and renew if necessary.
Locate the gasket (2) and the starter motor on the crankcase and tighten the bolts (1) to the specified torque (Sect. C 3, Frame torque settings.
Connect the starter motor/contactor cable (3).
Important
Fill the cap with protective grease before fitting it on the starter motor.
If the starting gears assembly has been renewed, refit the starter motor idler gear and the timing gears (Sect. N 9.1, Refitting the starter motor idler gear).
Refit the alternator-side crankcase cover (Sect. N 8, Reassembly of the alternator-side crankcase cover).
Starter contactor
The starter motor contactor (1) is elastically mounted to the airbox.
Disconnect the wiring connector (2) of the starter contactor from the wiring harness.
Disconnect the battery (Sect. P 2, Battery).
Remove the contactor from its seat.
Remove the protective caps (A).
Unscrew the nuts (4), taking care to recover the spring washers (3).
Remove the starter motor-contactor cable (2).
Remove the contactor-battery cable (5).
Disconnect the wiring connector (2) of the starter contactor from the wiring harness.
Checking operation of the starter contactor
Apply 12 V (battery voltage) across the positive terminal (A) and negative terminal (B) of the connector.
With a multimeter connected between the two poles (threaded studs (C) and (D)) of the contactor, check for electrical continuity (Sect. P 9, Using a multimeter to check the electrical systems). If there is no electrical continuity, renew the contactor.
On refitting, ensure that studs (C) and (D) are not oxidized; apply water repellent spray.
Position the cables (2) and (5) on the contactor terminals, orienting them as shown in the figure.
Insert the two bolts (3) and the nuts (5).
Tighten the nuts (4) to the specified torque (Sect. C 3, Frame torque settings).
Fit the contactor by inserting it on the tabs (E), orienting it as shown in the figure.
Refit the wiring connector (2) to the wiring and refit the protective caps (A).
