LIST OF SECTIONS
Foreword
This manual provides basic information about ordinary
vehicle servicing procedures.
The data and illustrations that make up the manual
were up to date at the time of publication.
The manual is intended for aprilia dealers and their
qualified mechanics. Many concepts have been intentionally omitted as they were considered superfluous.
Since this publication cannot provide exhaustive
mechanical knowledge, it is assumed that people who
make use of this manual have received a basic
training in mechanics and possess a working knowledge of vehicle repairing techniques.
Repairing or checking the vehicle without such knowledge would be ineffective and even dangerous.
As the repairing and checking procedures are not
described in full detail, special care should be taken to
avoid damage to property and personal injury.
With a view to providing its customers with the best
possible riding experience, aprilia is committed to
continually improving its products and the accompanying documentation.
aprilia dealers and world branches are informed about
all major technical modifications and changes in
repairing procedures. Such modifications will be
covered in later editions of this manual.
Should any need or doubt arise about repairing and
checking procedures, do not hesitate to contact aprilia’s
Consumer Service (A.C.S.): they will be pleased to
provide any information you may require and let you
know of any technical modifications and updates.

NOTES ON FUEL, LUBRICANTS, COOLANT AND OTHER ITEMS
FUEL
WARNING
The fuel used in internal combustion engines is highly flammable and can be explosive under certain
conditions.
Refuelling and servicing should be carried out in a well ventilated place after switching off the engine.
Do not smoke while refuelling or in the presence of fuel fumes. Avoid contact with open flames, sparks and
any other potential source of ignition or explosion.
Avoid spilling fuel from the tank filler as it may catch fire on contact with the hot engine surfaces.
Should any fuel be inadvertently spilled, be sure to dry up the area before starting the engine.
Since fuel expands when exposed to heat and direct sunlight, avoid filling the tank to the brim.
Carefully close the tank cap after refuelling.
Do not allow fuel to come into contact with the skin and avoid ingesting it or inhaling its fumes. Do not
transfer fuel from one vessel into another using a length of tube.
DO NOT DISPOSE OF FUEL IN THE ENVIRONMENT.
KEEP OUT OF REACH OF CHILDREN.
Use only leaded (4 Stars ) or unleaded premium grade petrol, min. O. N. 95 (N. O. R. M.) and 85 (N. O. M. M.).

General Information
Atlantic 500
CAUTION
Do not use brake fluids other than those prescribed. To avoid damaging the braking system, never mix
different types of fluids when topping up.
Never use brake fluid taken from an old container, or from a container that has been open for a long time.
Sudden changes in brake play or a spongy feel of the brake levers are due to problems in the hydraulic
circuits.
Take special care in ensuring that the brake discs and the brake linings are not oily or greasy, especially
after checking or servicing the brakes.
Ensure that the brake lines are not twisted or worn.
Take care not to let any water or dust into the brake circuit.
Latex gloves are recommended for all maintenance operations involving the hydraulic circuit.

COOLANT
WARNING
The coolant is harmful if ingested. Contact with the skin or the eyes may cause irritation. Should the liquid
come into contact with the skin or the eyes, generously rinse with water and seek medical attention.
If the fluid is ingested, cause vomiting, generously rinse the mouth and throat with water and immediately
seek medical attention.
DO NOT DISPOSE OF THE COOLANT IN THE ENVIRONMENT.
KEEP OUT OF REACH OF CHILDREN.
WARNING
Be careful not to spill the coolant on the red- hot parts of the engine: it may catch fire and send out invisible flames.
In case maintenance operations are to be performed, it is advisable to use latex gloves.
Do not use the vehicle if the coolant is below the minimum prescribed level“MIN”.
Check the coolant level before starting off and every 2,000 km (1,250 mi) (CHECKING AND RESTORING THE
COOLANT LEVEL). Renew the coolant every two years (RENEWING THE COOLANT).
The coolant is made up of 50% water and 50% antifreeze.This mixture is ideal for most running temperatures and
ensures good protection against corrosion.
It is advisable to keep the same mixture also in the hot season, since in this way losses due to evaporation are
reduced and it is not necessary to top up very frequently.
The mineral salt deposits left in the radiator by evaporated water are thus reduced and the efficiency of the cooling
system remains unchanged.
If the outdoor temperature is below 0°, check the cooling circuit frequently and if necessary increase the antifreeze
concentration (up to maximum 60%).
For the cooling solution use distilled water, in order not todamage the engine.
Engine coolant (recommended):
PARAFLU 11 FE (diluted).
Alternatively, use brand-name coolants with performance complying with or exceeding the specifications.
Antifreeze fluid based on monoethylene glycol, CUNA NC 958-16.
NOTE Different antifreezes have different characteristics. The degree of protection provided by each product is
specified on its label.
CAUTION
Only use nitrite-free antifreeze and anticorrosive providing protection to temperatures of at least -35° C
(31° F).

The engine and the exhaust components reach high temperatures during use and remain hot for some time
even after the engine has been switched off.
Before handling these components, put on insulating gloves or wait for the engine and the exhaust system
to cool down.
RUNNING-IN RULES
WARNING
After the first 1,000 km (625 mi), carry out the checking operations indicated in the column “After runningin” of the Regular Service Intervals Chart, see REGULAR SERVICE INTERVALS CHART, in order to avoid
hurting your-self or other people and/ or damaging the vehicle.
The running- in of the engine is primary to ensure its working life and its correct functioning. If possible, drive on
hilly roads and/or roads with many bends, so that the engine, the suspensions and the brakes
undergo a more effective running-in.
NOTE Only after the first 1,000 km (625 mi) of running-in it is possible to obtain the best speed and acceleration
performance from the vehicle.
Keep to the following indications:
• Do not open the throttle completely if the speed is low, both during and after the running-in.
• 0-100 km (0-62 mi)
During the first 100 km (62 mi) put on the brakes with caution, avoiding sharp and prolonged brakings.
This ensures a correct bedding-in of the pads on the brake disc.
• 0-500 km (0-312 mi)
During the first 500 km (312 mi), do not exceed the 80% of the maximum allowed speed.
• Avoid driving at constant speed for long distances.
• After the first 1,000 km (625 mi), progressively increase the speed until reaching the highest performance levels.

PRECAUTIONS AND GENERAL INFORMATION
When repairing, disassembling and reassembling the vehicle, scrupulously observe the following recommendations.
WARNING
The use of open flames is forbidden under all circumstances.
Before performing any servicing or checks, switch off the engine, remove the ignition key, allow the engine
and the exhaust system to cool down, and if possible lift the vehicle on solid level flooring using specific
equipment.
To avoid burns, pay special attention to hot engine and exhaust parts.
The vehicle is made up of inedible parts.
Non mordere, succhiare, masticare o ingerire nessuna parte dello stesso per nessun motivo.
Unless otherwise specified, the reassembly of parts is carried out by following the disassembling procedures in reverse order.
Avoid running the engine in closed or poorly ventilated places.
Petrol is highly flammable and explosive. Handle with the utmost care.
Never use fuel as a solvent to clean the vehicle.
When two or more people are working at the same time, pay attention to the safety of each of them.
– Only use GENUINE aprilia spares.
– Only use the recommended lubricants.
– Where provided, use the special tools designed for this type of vehicle.
– Start tightening the screws and nuts with a greater diameter or the inner ones, in a crosswise manner.
– Carefully clean the disassembled components using a detergent with a low degree of flammability.
– Lubricate the parts (when possible) before reassembling.
– Check that every component has been fitted properly.
– Always replace the gaskets, gas rings, piston rings, O rings and split pins with new ones.
– Mark the position on all the junction points (tubes, cables, etc.) before separating them.
Use different and clear identification marks as each part must be easily recognisable during the assembling
operations.
CAUTION
Never reuse circlips.
Always replace removed circlips with new ones.
When fitting a new circlip, take care not to part its ends more than is required to fit it on the shaft.
After fitting a circlip, ensure that it is fully and firmly inserted in its seat.
SPARE PARTS
Only use Genuine aprilia Spares.
All Genuine aprilia Spares are high-quality parts specially designed and manufactured for aprilia vehicles.
CAUTION
Using NON-genuine aprilia spares may result in damage and poor performance.

CAUTION
The brakes are the parts that most ensure your
safety and for this reason they must always be
perfectly working; check them before every trip.
A dirty disc soils the pads, with consequent
reduction of the braking efficiency. Dirty pads
must be replaced, while dirty discs must be
cleaned with a high-quality degreaser.
2
Renew the brake fluid every two years.
NOTE This vehicle is provided with front and rear
disc brakes, with separate hydraulic circuits.
The following information refers to a single braking
system, but is valid for both.
When the disc pads wear out, the brake fluid level in
the reservoir decreases to automatically compensate
for their wear.
The brake fluid reservoirs are located under the
handlebar cover, next to the brake lever connections.
Periodically check the brake fluid level in
the reservoirs, see beside (CHECK) and the wear of
the pads, see (CHECKING THE PADS WEAR).
WARNING
Do not use the vehicle if the braking system leaks
fluid.
CHECK
To check the level:
NOTE Put the vehicle on a solid and flat surface.
•
•
•
Put the vehicle on the central stand.
Turn the handlebar so that the fluid in the brake
fluid reservoir is at the same level as the “MIN”

CAUTION
Top up to the MAX level only if the brake pads are
new.
The level of the fluid gradually decreases with pad
wear.
Topping up to the MAX level when the pads are
worn will cause the brake fluid to overflow when
the pads are replaced.
Fill reservoir (3) with brake fluid (see LUBRICANT

CHECKING BRAKE PAD WEAR
Read through the paragraph DISC BRAKES.
The following information are referred to one
braking system only, but are valid for both.
Check the brake pad wear after the first 1,000 km (625
mi) and successively every 2,000 km (1,250 mi).
The wear of the brake pads depends on the use, on
the kind of drive and on the road.
The wear is heavier when driving on dirty or wet
roads.
FRONT BRAKE CALIPER
– Front side from the bottom for both calipers.
REAR BRAKE CALIPER
– Rear side from the bottom for both pads (C).
WARNING
The excessive wear of the friction material would
cause the contact of the pad metal support with
the disc, with consequent metallic noise and
production of sparks from the caliper; braking
efficiency, safety and soundness of the disc would
thus be negatively affected.
•
If the thickness of the frictional material (also of
one pad only) becomes 1.5 mm (0.059 in), replace
both pads (both front and rear pad).

CHECKING THE FRONT SUSPENSION
Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
Inspect the front suspension after the first 1,000 km
(625 mi) and then every 6,000 km (3,750 mi) or 8
months.
Renew the oil in the front suspension every 12,000 km
(7,500 mi), see FRONT SUSPENSION.
Check that no oil is leaking from the fork, and that the
outside surface of the fork rods is not scratched or
grooved. Replace any damaged parts.
Also perform the following checks:
While pulling the front brake lever, repeatedly stroke
the fork by pushing down on the handlebar. The fork
should move smoothly, and there should be no traces
of oil on the fork rods.
Check the tightening of all parts and the function of the
front suspension joints (see FRONT SUSPENSION).

CHECKING THE REAR SUSPENSION
Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
Inspect the rear suspension after the first 1,000 km
(625 mi) and subsequently every 6,000 km (3,750 mi)
or 8 months.
Check that no oil is leaking from the shock absorbers.
Check the tightening of all parts and the function of
the rear suspension joints (see REAR SUSPENSION).
CAUTION
Check that both shock absorbers are adjusted to
the same position. See (ADJUSTMENT).
ADJUSTING THE REAR SUSPENSION
Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
The rear suspension consists of a doubleeffect shock
absorber (braking with compressed/extended shock
absorber) fixed to the engine by means of a silentblock.
The standard adjustment, set by the manufacturer, is
suitable for a driver weighing about 70 kg (154.3 lbs).
If your weight and needs are different, adjust the ring
nut (1) with the appropriate spanner provided in the

WHEELS AND TYRES
Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
WHEELS INSPECTION
Check that the wheel rims are not cracked or distorted. If necessary replace them.
Check the radial runout of the wheel.
If the wheel is distorted beyond the acceptable limit,
check the condition of the rim and the bearings.
If necessary replace the wheel.
Runout limits:
Vertical runout: 2 mm (0.078 in)
Lateral runout: 2 mm (0.078 in)
Check the wheel trim.
Slowly turn the wheel several times and observe the
point at which it stops.
If the wheel is not statically balanced, it will always
stop at the same point. Fit a balancing weight at the
lightest point (top).
TYRES
Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
This vehicle is provided with tubeless tyres.
WARNING
Periodically check the tyre inflation pressure at
room temperature, see (TECHNICAL DATA).
If the tyres are hot, the measurement is not correct.
Carry out the measurement especially before and
after long rides.
If the inflation pressure is too high, the ground
unevenness cannot be dampened and is therefore
transmitted to the handlebar, thus compromising
the driving comfort and reducing road holding
during turns.

If, on the contrary, the inflation pressure is too
low, the tyre sides (1) are under greater stress and
the tyre itself may slip on the rim or it may become loose, with consequent loss of control of
the vehicle.
In case of sudden braking the tyres could even get
out of the rims.
Further, the vehicle could skid while turning.
1
2
Check the surface and the wear of the tyres, since
tyres in bad conditions can impair both the grip
and the controllability of the vehicle.
Some types of tyres homologated for this vehicle
are provided with wear indicators.
There are several kinds of wear indicators.
Visually check if the tyres are worn and in this
case have them changed.
If the tyres are old, even if not completely worn
out, they may become hard and may not ensure
good road holding.In this case, have the tyres
changed.
Change the tyre when it is worn out or in case of
puncture on the tread side, if the puncture is
larger than 5 mm (0.196 in).
After repairing a tyre, have the wheels balanced.
Use only tyres in the size suggested by aprilia,
see TECHNICAL DATA.
Do not install tyres with air tube on rims for tubeless tyres and viceversa.
Make sure that the tyres always have their valve
sealing caps on, to prevent them from suddenly
going flat.
Change, repair, maintenance and balancing operations are very important and should be carried out
by qualified technicians with appropriate tools.
If the tyres are new, they may still be covered with
a slippery film: drive carefully for the first miles.
Do not oil the tyres with unsuitable fluids.

FUEL TANK AND PUMP
EMS FUEL INJECTION SYSTEM
The fuel injection system used is of the integrated fuel injection and ignition type.
Fuel is injected indirectly into the manifold by means of the electroinjector.
Fuel injection and ignition are timed on a 4-stroke cycle via a phonic wheel keyed to the cam shaft control and a
reluctance variation sensor.
Fuel supply and ignition are controlled in relation to the engine revolutions and the opening of the throttle control.
Further corrections are carried out on the basis of the following parameters:
- Coolant temperature
- Air intake temperature
- Environmental pressure
The system carries out a idling supply correction on a cold engine via a stepper motor inserted on to a by-pass
circuit of the throttle valve. The control unit controls the stepper motor and the timing of the injector opening, thus
guaranteeing idling stability and correct fuel supply.
Under all working conditions, fuel supply is controlled by modifying the injector opening time.
Petrol supply pressure is kept constant on the basis of environmental pressure.
The supply circuit is composed of:
- Fuel pump
- Fuel filter
- Injector
- Pressure regulator
The pump, filter and regulator are inserted into the fuel tank via a single support.
The injector is connected by means of two snap-connector tubes. This allows continuous circulation and avoids the
risk of fuel overheating. The pressure regulator is situated at the end of the circuit. The fuel pump is controlled by
the EMS control unit; thus guaranteeing vehicle safety.
The ignition circuit is composed of:
- H.V. coil
- H.V. cable
- Shielded cap
- EMS control unit
- Spark plug
The EMS control unit controls ignition with optimum advance, at the same time guaranteeing 4-stroke cycle timing
(ignition only during compression phase).
The EMS fuel injection-ignition system controls the working of the engine by means of a preset programme.
Should certain entry signals fail, an acceptable working of the engine is still guaranteed in order that the user may
reach a repairs centre.
Obviously, this will not happen if the revolutions signal fails, nor if there is an anomaly in the control circuit:
- Fuel pump
- H.V. Coil
- Injector

SYSTEM DESCRIPTION
The cooling system is constructed with a centrifugal pump coaxial to the countershaft and as such completes a
number of revolutions identical to that of the driving shaft.
The pump has two ducts, one for entry and one for exit.
The exit duct supplies the cylinder and consequently the cylinder head; the entry duct leads from the cylinder head
and its entrance to the pump is controlled by the thermostat plate.
The main stabilizer of the thermostat acts instead on the main pump entry duct leading from the radiator.
The radiator is fed from the cylinder head exit; the expansion tank is inserted parallel to the radiator with the ducts
on two levels: the delivery high up (in the air) and the fluid return low down (in the fluid).
The system thus composed is 2-way.
The first way is the internal engine circulation and involves the pump, cylinder and cylinder head; this circulation is
fully active when the thermostat is fully closed.
The second way is active with the thermostat fully open and is the main circulation which involves the pump,
cylinder, cylinder head, radiator and expansion tank; for medium openings of the thermostat, however, the two
circuits are both partially inserted, therefore the two ways are superimposed.
This kind of circuit is defined as the type with inlet thermostat. The thermostat is crossed by an inverted flow, that is
with cold water which tends to lower the temperature of the wax cell.
This system allows optimization of the engine heating phases.
The expansion tank, parallel to the radiator and inserted on the main circuit, guarantees autodraining when working.
For the filling stages of the system there is a drain exiting from the cylinder head (see filling rules).
The electrical fan is controlled by the fuel injection system with temperature measured on the cylinder head of the
engine.

CHECKING THE COMPONENTS
Rod
The sliding surface must show no signs of scoring and/
or damage.
If the rod is damaged, replace it.
With a dial gauge, check that the rod bending is lower
than the limit value.
If necessary, replace the rod.
Bending limit: 0.2 mm (0.007 in).
WARNING
A bent rod must NEVER be straightened as its
structure would become weak, thus compromising
the vehicle safety.
Wheel carrier
Check that it shows no signs of damage and/or flaws.
Replace if necessary.
Spring
Check the spring condition.
Pumping element
Check the pumping element condition.
Replace if it shows signs of damage.
ADJUSTING THE REAR SUSPENSION
The rear suspension consists of a doubleeffect shock
absorber (braking with compressed/extended shock
absorber) fixed to the engine by means of a silentblock.
The standard adjustment, set by the manufacturer, is
suitable for a driver weighing about 70 kg (154.3 lbs).
If your weight and needs are different, adjust the ring
nut (1) with the appropriate spanner provided in the
tool kit, thus setting the ideal travelling conditions (see
table).
Adjust both shock absorbers to the same position.
