Carbon monoxide
If you need to keep the engine running in order to carry out any procedure, please ensure that you do
so in an open or very well ventilated area. Never let the engine run in an enclosed area. If you do work
in an enclosed area, make sure to use a smoke-extraction system.
CAUTION
EXHAUST EMISSIONS CONTAIN CARBON MONOXIDE, A POISONOUS GAS WHICH CAN CAUSE
LOSS OF CONSCIOUSNESS AND EVEN DEATH.
Fuel
CAUTION
FUEL USED TO POWER INTERNAL COMBUSTION ENGINES IS HIGHLY FLAMMABLE AND CAN
BECOME EXPLOSIVE UNDER SPECIFIC CONDITIONS. IT IS THEREFORE RECOMMENDED TO
CARRY OUT REFUELLING AND MAINTENANCE PROCEDURES IN A VENTILATED AREA WITH
THE ENGINE SWITCHED OFF. DO NOT SMOKE DURING REFUELLING AND NEAR FUEL VAPOURS, AVOIDING ANY CONTACT WITH NAKED FLAMES, SPARKS OR OTHER SOURCES
WHICH MAY CAUSE THEM TO IGNITE OR EXPLODE.
DO NOT DISPERSE FUEL IN THE ENVIRONMENT.
KEEP OUT OF THE REACH OF CHILDREN
Hot components
The engine and the exhaust system components get very hot and remain in this condition for a certain
time interval after the engine has been shut off. Before handling these components, make sure that you
are wearing insulating gloves or wait until the engine and the exhaust system have cooled down.
Coolant
The coolant contains ethylene glycol which, under certain conditions, can become flammable.
When it burns, ethylene glycol produces an invisible flame which however can cause burns.
CAUTION
PAY ATTENTION NOT TO POUR COOLANT ON HOT ENGINE OR EXHAUST SYSTEM COMPONENTS; IT MAY CATCH FIRE PRODUCING INVISIBLE FLAMES. IT IS ADVISABLE TO WEAR
LATEX GLOVES WHEN SERVICING THE VEHICLE. EVEN IF IT IS TOXIC, THE COOLANT HAS A
SWEET FLAVOUR WHICH MAKES IT VERY ATTRACTIVE TO ANIMALS. NEVER LEAVE THE
COOLANT IN OPEN CONTAINERS IN AREAS ACCESSIBLE TO ANIMALS AS THEY MAY DRINK
IT.

SERVICING THE SYSTEMS. BRAKE AND CLUTCH FLUIDS ARE EXTREMELY HARMFUL FOR
YOUR EYES. IN THE EVENT OF ACCIDENTAL CONTACT WITH THE EYES, RINSE THEM IMMEDIATELY WITH ABUNDANT COLD, CLEAN WATER AND SEEK MEDICAL ADVICE.
KEEP OUT OF THE REACH OF CHILDREN
Battery electrolyte and hydrogen gas
CAUTION
THE BATTERY ELECTROLYTE IS TOXIC, CORROSIVE AND AS IT CONTAINS SULPHURIC ACID,
IT CAN CAUSE BURNS WHEN IN CONTACT WITH THE SKIN. WHEN HANDLING BATTERY
ELECTROLYTE, WEAR TIGHT-FITTING GLOVES AND PROTECTIVE APPAREL. IF THE ELECTROLYTIC FLUID COMES INTO CONTACT WITH THE SKIN, RINSE WELL WITH ABUNDANT
FRESH WATER. IT IS PARTICULARLY IMPORTANT TO PROTECT THE EYES BECAUSE EVEN
TINY AMOUNTS OF BATTERY ACID MAY CAUSE BLINDNESS. IF THE FLUID GETS INTO CONTACT WITH YOUR EYES, WASH WITH ABUNDANT WATER FOR FIFTEEN MINUTES AND CONSULT AN EYE SPECIALIST IMMEDIATELY. IF THE FLUID IS ACCIDENTALLY SWALLOWED,
DRINK LARGE QUANTITIES OF WATER OR MILK, FOLLOWED BY MILK OF MAGNESIA OR
VEGETABLE OIL AND SEEK MEDICAL ADVICE IMMEDIATELY. THE BATTERY RELEASES EXPLOSIVE GASES; KEEP IT AWAY FROM FLAMES, SPARKS, CIGARETTES OR ANY OTHER
HEAT SOURCES. ENSURE ADEQUATE VENTILATION WHEN SERVICING OR RECHARGING
THE BATTERY.

Maintenance rules
GENERAL PRECAUTIONS AND INFORMATION
CHAR - 3
Characteristics
SL 750 SHIVER
When repairing, dismantling and reassembling the vehicle follow the recommendations reported below
carefully.
BEFORE DISASSEMBLING COMPONENTS
•
Before dismantling components, remove dirt, mud, dust and foreign bodies from the vehicle.
Use the special tools designed for this bike, as required.
COMPONENTS REMOVAL
•
Do not loosen and/or tighten screws and nuts using pliers or other tools other than the
especially designed wrench.
•
Mark positions on all connection joints (pipes, cables, etc.) before separating them, and
identify them with distinctive symbols.
•
Each component needs to be clearly marked in order to be identified during assembly.
•
Clean and wash the removed components carefully using a low-flammability detergent.
•
Keep coupled parts together since they have "adjusted" to each other due to normal wear
and tear.
•
Some components must be used together or replaced altogether.
•
Keep away from heat sources.
REASSEMBLING COMPONENTS
CAUTION
BEARINGS MUST BE ABLE TO ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE, OTHERWISE THEY NEED REPLACING.
•
Only use ORIGINAL APRILIA SPARE PARTS.
•
Comply with lubricant and consumables usage guidelines.
•
Lubricate parts (whenever possible) before reassembling them.
•
When tightening nuts and screws, start from the ones with the largest section or from the
internal ones, moving diagonally. Tighten nuts and screws in successive steps before applying the tightening torque.
•
Always replace self-locking nuts, washers, sealing rings, circlips, O-rings, split pins and
screws with new ones if their tread is damaged.
•
When fitting bearings, make sure to lubricate them well.
•
Check that each component is fitted correctly.
•
After a repair or routine maintenance procedure, carry out pre-ride checks and test the vehicle on private grounds or in an area with low traffic density.
•
Clean all junction surfaces, oil guard rims and washers before refitting them. Smear a light
layer of lithium-based grease on the oil guard rims. Reassemble the oil guard and the bearings with the brand or lot number facing outward (visible side).
ELECTRIC CONNECTORS
Electric connectors must be disconnected as described below as non-compliance with the procedure
so described causes irreparable damage to both the connector and the cable harness:
CHAR - 4
SL 750 SHIVER
Characteristics
Press the relevant safety hooks, if any.
•
Grip the two connectors and disconnect them by pulling them in opposite directions.
•
If there are signs of dirt, rust, humidity, etc., clean the connector internal parts carefully using
a pressurised air jet.
•
Make sure that the cables are correctly linked to the connector internal terminal ends.
•
Then insert the two connectors making sure that they couple correctly (if the relevant hooks
are provided, you will hear them "click" into place).
CAUTION
TO DISCONNECT THE TWO CONNECTORS, DO NOT PULL THE CABLES.
NOTE
THE TWO CONNECTORS CONNECT ONLY FROM ONE SIDE: CONNECT THEM THE RIGHT WAY
ROUND.
TIGHTENING TORQUE
CAUTION
DO NOT FORGET THAT THE TIGHTENING TORQUE OF ALL FASTENING ELEMENTS ON
WHEELS, BRAKES, WHEEL SPINDLES AND OTHER SUSPENSION COMPONENTS PLAY A KEY
ROLE IN ENSURING THE VEHICLE'S SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.
CHECK THE TIGHTENING TORQUE OF FASTENING PARTS ON A REGULAR BASIS AND ALWAYS USE A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO COMPLY WITH THESE RECOMMENDATIONS MAY CAUSE ONE OF THESE COMPONENTS TO GET
LOOSE AND EVEN DETACHED, THUS BLOCKING A WHEEL, OR OTHERWISE COMPROMISE
VEHICLE HANDLING. THIS CAN LEAD TO FALLS, WITH THE RISK OF SERIOUS INJURY OR
DEATH.
Running-in
Engine run-in is essential to ensure engine long life and correct operation. Twisty roads and gradients
are ideal to run in engine, brakes and suspensions effectively. Vary your driving speed during run-in.
In this way, you allow for the work of components to be "loaded" and then "unloaded", thus cooling
engine parts.
CAUTION
ONLY AFTER THE SERVICE AT THE END OF THE RUN-IN PERIOD CAN THE BEST PERFORMANCE OF YOUR VEHICLE BE OBTAINED.
Follow the guidelines detailed below:
•
Do not twist the throttle grip abruptly and completely when the engine is working at a low
revs, either during or after run-in.
•
During the first 100 km (62 miles) operate the brakes with caution, avoid rough and long
braking. That is to permit the adequate adjustment of the pad friction material to the brake
discs.
AFTER THE SPECIFIED MILEAGE, TAKE YOUR VEHICLE TO AN Official aprilia Dealer FOR THE
CHECKS INDICATED IN THE "AFTER-RUN-IN" TABLE IN THE SCHEDULED MAINTENANCE
SECTION, TO AVOID INJURING YOURSELF, OTHERS AND/OR DAMAGING THE VEHICLE.

Checks and inspections
GENERAL CONCEPTS OF ELECTRICAL TROUBLESHOOTING
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING PROCEDURE ON THE VEHICLE, CHECK
THAT THE BATTERY VOLTAGE IS ABOVE 12V.
CONNECTOR CHECK PROCEDURE
The procedure includes the following checks:
1. Observation and check of the connector position
on the component or on the coupling connector,
making sure that the locking catch is released.
2. Observation of the terminals on the connector:
no rust marks or dirt should be present and it is
important to check terminal correct positioning on
the connector (i.e., all terminals aligned at the
same depth) and terminal integrity (i.e., that terminals are not loose, open/bent, etc.). For connectors whose terminals are not visible (e.g. Marelli
control unit) use a metal cable of suitable diameter
and introduce it carefully in the connector slot at
the same depth as for the other terminals of the
connector.
CAUTION
IN CASE OF TEMPORAL MALFUNCTIONING,
CARRY OUT ALL DUE CHECKS LOOKING FOR
FAILURES BY MOVING SLIGHTLY THE CABLE
HARNESS BEING INSPECTED.
3. Pulling the cables slightly from the back of the connector in order to check the correct position of the
terminals on the connector and of the cable on the terminal.
CONTINUITY check
Check goal: this control is to check that there are not any circuit interruptions nor excessive resistance,
for instance caused by rust, on the two terminals being inspected.
ELE SYS - 22
SL 750 SHIVER
Electrical system
Tester: set the tester on the "continuity" symbol and place the tester probes on the two circuit ends:
the tester emits a sound signal only if there is continuity; the tester can also be set to the Ohm symbol
to check that the circuit resistance is null or a few tenths of an Ohm.
CAUTION: THE CIRCUIT SHOULD NOT BE ENERGISED, OTHERWISE THE TEST IS IRRELEVANT.
GROUND CONNECTION check
Check goal: this control is to check if a cable or a circuit is in contact with the vehicle ground (-)
connection.
Tester: set the tester on the "continuity" symbol and place one tester probe on the vehicle ground
connection (or on the battery - terminal) and the other probe on the cable being inspected: the tester
sends out a sound signal only if there is continuity. The tester can also be set to the Ohm symbol to
check that the circuit resistance is null or a few tenths of an Ohm.
CAUTION! IF THERE IS A GROUND CONNECTION COMING FROM THE CONTROL UNIT, MAKE
SURE THAT DURING THE TEST THE CONTROL UNIT IS EARTH CONNECTED TO THE CIRCUIT.
VOLTAGE check
Check goal: this control is to check if a cable is energised, i.e. if it receives power supply from the
battery or the control unit.
Tester: set the tester on the direct current symbol and place the tester red probe on the cable being
inspected and the black probe on the vehicle ground connection (or on the battery - terminal).
CAUTION
IN CASE OF TEMPORAL MALFUNCTIONING, CARRY OUT ALL DUE CHECKS LOOKING FOR
FAILURES BY MOVING SLIGHTLY THE CABLE HARNESS BEING INSPECTED.
Dashboard
In case the EFI warning light turns on and the words SERVICE or URGENT SERVICE are shown on
the display, due to an error detected in the injection ECU, the malfunction indication will be deactivated
only after the vehicle has been used for a pre-set number of minutes of operation. However, even though
the malfunction is no longer present and the control unit considers the error no longer current but memorised (MEM error indication on Axone), the instrument panel may keep showing there is an error
present.

Marelli control unit.
AXONE: NOTES
After installing the control unit and setting the key to ON, wait for 3 seconds, time during which the
control unit detects the throttle valve position.
Connect to Axone and check that the status for Throttle Self-learning is Carried out and the status
for Throttle grip autodetection is Not carried out(this last status entails Urgent service being displayed on the instrument panel).
If Throttle Self-learning shows Not carried out , go to stage 1. If it shows Carried out, go to stage 2.
Stage 1: current errors have probably been detected by the control unit: solve these malfunctions and
check the Throttle Self-learning status again. Throttle Self-learning can also be checked from the Parameter adjustment (screwdriver and hammer) screen page.
Stage 2: Carry out the Throttle Self-learning from the Parameter adjustment (screwdriver and hammer)
screen page and check that Throttle Self-learning status is Carried out. If it is not correct or the voltage
detected on the throttle is out of scale (check with Axone) or if current errors are probably detected by

Twistgrip position sensor
THROTTLE GRIP POSITION SENSOR
Function
The throttle grip is the part to which the throttle control cables arrive; its task is to translate the rider's
power request (Demand) into an electrical signal to be sent to the electronic control unit.
Operation / Operating principle
The two throttle cables (opening and closing) actuate on a scroll mounted on a shaft which is sent back
to its home position by a return spring. On the shaft covers there are 2 double track potentiometers (4
control tracks) by means of which the torque demand is read (and checked). The 4 potentiometers are
tinned and magnetically controlled (contactless); they cannot be overhauled nor replaced

for example, value 0.75 corresponds to +25% with respect to the reference injection time; 1.25 corresponds to -25%. In an open circuit, the lambda probe signal is too low. Therefore, the control unit takes
it as a lean combustion condition and will try to enrich it. The value read will be 0.75: once this correction
has been tried, the value shifts to 1.00 fixed and the Lambda probe error is signalled.
AXONE: STATUSES
Lambda
Example value:Start-up_Lean_Rich_Fault due to rich value_Fault due to lean value
If the probe connector is removed (voltage almost equal to zero), the status is Fault due to lean value
Lambda check
Example value: Open loop/Closed loop/Rich in closed loop/Lean in closed loop/enriched
Closed loop indicates that the control unit is using the lambda probe signal to keep the combustion as
close as possible to the stoichiometric value.

Throttle body
THROTTLE BODY
Function
To inform the throttle control unit the position of the
two throttle valves and to drive them both.
Operation / Operating principle
All the unit internal components (potentiometer
and electric motor) are contactless; therefore, no
electrical diagnosis is possible for the throttle
body, only for the circuits connected to it.
Throttle body activation takes place every time the key is set to ON: correct activation is indicated when the stop lights turn on.
If during activation, the engine is started, the activation is not completed and the stop lights do
not turn on.
Every 150 key-ONs, however, the throttle valves are forced to activation. If start-up is attempted
during this activation (which requires 3 seconds), the engine will not start.

Front throttle Potentiometer 1 - 2 (degrees) / Rear throttle Potentiometer 1 - 2 (degrees)
Example value: 6.5°
With key set to ON, the throttle is kept in position by the springs (approximately 5 - 7°). After the engine
starts up at idle, the throttle is kept close to the mechanical minimum (above or equal to 0.5°). When
the gear is not engaged, at approx. 6000 rpm, throttles open very little because the requested torque
is too low (approximately 5 - 7°).
Front / rear cylinder throttle correction
Example value: 0.0°
For example, if there is a hole in the intake manifold, the pressure read is different from the pressure
estimated by the control unit and the system tries to reach an "estimated" situation by opening the
throttle a little bit more; therefore, this parameter takes a value different from zero: an acceptable value
should be between -0.7º and +0.7º.

Ride by Wire
RIDE BY WIRE
Operating logic
Those riding motorbikes do not require a specific throttle valve opening from their engines but actually
a specific torque. The Ride by Wire system has been so designed that the throttles of the throttle bodies
are mechanically isolated from the throttle control; their actuation depends exclusively on 2 electrical
motors controlled by the control unit. Therefore, there is a "Throttle map" to which the control unit refers
in order to decide the position at which the throttle valves should be and at what speed they should
reach the pre-set position. The main parameters which influence the throttle map are:
•
Throttle position and opening/closing speed
•
Engine rpm
•
Inlet pressure read at each inlet manifold
•
Rear and front throttle valve position
•
Air temperature
The functions required from the Marelli control unit therefore are:
1. Ride by Wire system control (throttle map)
2. Injection/ignition control
3. System safety checks
1 - Ride by Wire system control
THROTTLE GRIP POSITION SENSOR The throttle grip is the part to which the throttle control cables
arrive; its task is to translate the rider's power request into an electrical signal to be sent to the electronic
control unit. The two throttle cables (opening and closing) actuate on a scroll mounted on a shaft and
which is sent back to its home position by a return spring.
On the shaft covers there are 2 double track potentiometers (4 control tracks) by means of which the
torque demand is read (and checked).
Marelli 5DM electronic control unit Besides the regular control functions of the injection system, it
supervises the throttle bodies: Through the throttle grip position sensor, it reads the torque demand
and, through the THROTTLE MAP, it decides the throttle opening and sends the command to the throttle
valve control unit. It checks the correct operation of each component (Self-diagnosis), of the system
(Safety), and carries out the emergency procedure (Recovery).
EFI throttle control unit The control unit receives the target throttle opening to be carried out and it
actuates on the control acting on the throttle body motors.
It checks (through the throttle position sensor signal) that the throttle bodies have reached the target
position.
It communicates the position reached to the Marelli control unit. It does not actuate on Safety strategies.

SL 750 SHIVER
Throttle Body The two throttle bodies are made up of:
•
Throttle valve with 2 return springs for the controlled minimum opening position.
•
DC electrical motor
•
Tinned double throttle position sensors with magnetic control (contactless)
The throttle bodies do not require any maintenance and cannot be overhauled. In case of electric or
mechanic malfunction, replace the whole unit.
Pressure sensors The pressure sensors (one per cylinder) are fundamental not only for the injection
map at low and stabilised speeds but also for checking the Ride by Wire system: their signal is connected
to a TORQUE CHAIN for checking the correct opening of the throttle valves.
Intake air temperature sensor The signal coming from the sensor is used to calculate the estimated
torque since the oxygen in the air also depends on its density which varies according to temperature.
2 - Injection/ignition control
Map for injection type (alpha-D)/rpm where:
•
alpha is the throttle position
•
D is the pressure measured at inlet ducts
•
Rpm are the engine revolutions
•
At idle and for slow and stabilised speeds D/n
•
For medium-high throttle openings alpha/n
•
For temporary speed (speed change) alpha/n
•
The main parameters that correct the injection map are:
•
Engine temperature
•
Atmospheric pressure (calculated)
•
Lambda probe signal
•
Air temperature
3 - System safety checks
The checks are structured in several levels:
•
Level 1 - sensor correct operation
•
Level 2 - comparison between requested torque and estimated torque generated by the
engine
•
Level 3 - a microprocessor controls the correct operation of the regular microprocessor
The consequent maintenance operations may be of different gravity according to the level and the
defective component:
A the malfunction does not affect riding in safety, the warning light turns on, the word Service is displayed, the signal recovery value considered not reliable is used and the engine works regularly.
B the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service is
displayed, the torque demands are not fully activated (reduced torque).
C the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service
is displayed, the engine operates in Limp Home function (accelerated idle), the throttles which are at

the position exclusively depending on the springs are not moved. The engine may shut off during the
operation if it is running at idle speed and the gear is in neutral.
D the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service
is displayed, the engine stops running.

Bleeding the braking system
Front
If there is air in the hydraulic system, it acts as a bearing, absorbing a large part of the pressure from
the brake pump and minimising calliper efficiency during braking.
The presence of air is signalled by the "sponginess" of the brake control and poor braking efficiency.
CONSIDERING THE DANGER FOR VEHICLE AND RIDER, IT IS STRICTLY NECESSARY, AFTER
REFITTING BRAKES AND RESTORING THE BREAKING SYSTEM TO THE REGULAR USE CONDITIONS, THAT THE HYDRAULIC CIRCUIT BE AIR PURGED.
NOTE
BRAK SYS - 5
Braking system
SL 750 SHIVER
THE FOLLOWING OPERATIONS REFER TO ONLY ONE FRONT BRAKE CALLIPER BUT APPLY
TO BOTH CALLIPERS. THE VEHICLE MUST BE ON LEVEL GROUND TO BE PURGED. WHILE
PURGING THE HYDRAULIC SYSTEM, FILL THE RESERVOIR WITH THE NECESSARY QUANTITY
OF BRAKE FLUID. CHECK THAT, DURING THE OPERATION, THERE IS ALWAYS BRAKE FLUID
IN THE RESERVOIR.
•
Remove the rubber protection cover
from the bleed valve.
•
Insert the transparent plastic pipe in
the front brake calliper bleed valve and
slide the other end of this pipe in a container to collect the fluid.
•
Remove the front brake oil reservoir
cap.
•
Quickly press and release the front
brake lever several times and then
keep it fully pressed.
•
Loosen the bleed valve 1/4 of a turn so
that the brake fluid flows into the container. This will release the tension on
the brake lever and will make it reach
the end of stroke.
•
Close the bleed valve before the lever
reaches its end of stroke.
•
Repeat the operation until the fluid
draining into the container is air-bubble
free.
NOTE
WHILE PURGING THE HYDRAULIC SYSTEM,
FILL THE RESERVOIR WITH THE NECESSARY
QUANTITY OF BRAKE FLUID. CHECK THAT,
DURING THE OPERATION, THERE IS ALWAYS
BRAKE FLUID IN THE RESERVOIR.
•
Screw the bleed valve and remove the pipe.
•
Top-up the reservoir until the correct brake fluid level is obtained.
