This manual contains all the main information and the in-

structions required for normal use and maintenance of

your vehicle.

For controls and check-ups that cannot be carried out

easily with the standard equipment supplied, we advise

you to consult our Dealers who can assure you of quick

and careful servicing.

To keep your aprilia vehicle always in perfect operating

conditions, we advise you to insist on Original Spares

and to have repairs carried out only by aprilia Author-

ized Outlets and Official Dealers.

When ordering spare parts from the Dealer, always

quote the spares code which is stamped on a sticker

placed under the saddle.

It is a good idea to make a note of the identification code

in the space provided in this manual, so that you will al-

ways have a record of it even if the identification sticker

comes off

Avoid parking the vehicle catalytic version

near dry brush wood or in places easily ac-

cessible to children, as the catalytic silencer

becomes extremely hot during use; be very careful

and avoid any kind of contact before it has com-

pletely cooled down.

The catalytic Amico 50 is fitted with a silencer with metal

catalytic converter of the "platinum-rhodium bivalent"

type. This device provides for the oxidation of the CO

(carbon monoxide) and of the HC (unburned hydrocar-

bons) contained in the exhaust gases, changing them

into carbon dioxide and steam, respectively.

Due to the catalytic reaction, the high temperature

reached by the exhaust gases makes for the burning of

the oil particles, thus keeping the silencer clean and

eliminating the exhaust fumes.

To have the catalytic converter function correctly and for

long and to reduce possible problems regarding the soil-

ing of the thermal unit and of the exhaust, it is necessary

to avoid covering long distances with the engine running

at constantly low rpm.

It is sufficient to alternate these periods with periods in

which the engine runs at relatively high rpm, even if only

for a few seconds, but rather frequently.

What has been stated above assumes particular impor-

tance for the cold starting of the engine: in this case, in

order to reach a rpm regime sufficient to enable the

"priming" of the catalytic reaction, just make sure that the

temperature of the thermal unit has reached at least

50°C, which generally occurs a few seconds after start-

ing the engine.

Do not use leaded petrol, since it causes the

destruction of the catalytic converter.

Exhaust gases contain carbon monoxide,

which is extremely noxious if inhaled.

Avoid starting the vehicle in closed or badly-

ventilated rooms.

The non-observance of this warning may cause loss

of consciousness or even lead to death by asphyxia.

Do not get on the vehicle for the starting.

Electric starting

◆

Position the vehicle on the stand.

◆

Lock at least one wheel, by pulling a brake lever (Fig.

7). If this operation is not carried out, the start relay re-

ceives no current and therefore the engine does not

start.

◆

Turn the ignition switch (Fig. 8) to position "n".

◆

Press the start push button “

” (1-Fig. 9) without accel-

erating, then release it as soon as the engine starts.

Avoid pressing the start push button "

(3) when the engine is running: this may

damage the starter.

When the start push button "

r" is pressed, the 2

stroke oil reserve warning light "

j" comes on.

With the engine in running condition, when the start

push button "

r" is released, the 2 stroke oil reserve

warning light "

j" must go out; if this does not oc-

cur, top up the 2 stroke oil tank

◆

If the starting is carried out with cold engine, rotate the

cold start lever "

e" (1-Fig. 10) downwards.

◆

Do not accelerate and pull the brake levers at the

same time until you move off.

◆

Warm the engine up before leaving.

◆

Once the engine has warmed up, rotate the cold start

lever "

e" (1-Fig. 10) upwards.

For the kick start, proceed as follows:

◆

Position the vehicle on the centre stand.

◆

Move to the left side of the vehicle.

◆

To avoid losing control of the vehicle during the start-

ing, lock both wheels by putting on the brake levers

(Fig. 7).

◆

Turn the ignition switch (Fig. 8) to position "n".

Do not push down the kick starter with the

engine on.

◆

Push down the kick starter with your right foot, releas-

ing it immediately.

If necessary, repeat the operation until the engine

starts.

After a long period of inactivity, proceed as follows:

◆

Move the ignition switch (Fig. 8) to position "n".

◆

Make the starter run for about 10 seconds, in order to

ensure the filling up of the float chamber.

To start the engine:

◆

Rotate the cold start lever "e" (1-Fig. 10) downwards.

◆

Slightly open the throttle, then carry out the electric

starting procedure (or KICK START).

Release the throttle grip (Pos. A - Fig. 11), put on the

rear brake, then move the vehicle down the stand.

Get on the vehicle, keeping at least one foot on the

ground in order not to lose balance.

Properly adjust the inclination of the rear-

view mirrors.

To leave, release the brake lever and accelerate by gen-

tly rotating the throttle grip (Pos. B - Fig. 11); the vehicle

will start moving.

Avoid opening and closing the throttle grip

repeatedly and continuously, so that you do

not accidentally lose control of the vehicle.

If you have to brake, close the throttle and put on

both brakes in order to obtain uniform deceleration,

properly exerting pressure on the braking parts.

By putting on the front brake only or the rear brake

only, you reduce the braking force considerably,

thus running the risk of locking one wheel and con-

sequently losing grip.

Before beginning to turn, slow down or brake driv-

ing at moderate and constant speed or accelerating

slightly; avoid braking at the last moment: it would

be very easy to skid.

If the brakes are operated continuously on

downhill stretches, the friction surfaces can

overheat, thus reducing the braking efficien-

cy. Never drive with the engine off!

In case of wet ground or scarce wheel grip (snow,

ice, mud, etc.), drive slowly, avoiding sudden brak-

ings or manoeuvres that could make you lose grip

and fall down.

Pay the utmost attention to any obstacle or variation

of the ground.

Uneven roads, rails, manhole covers, indications

painted on the road surface, building site metal

plates become rather slippery by rain. For this rea-

son all these obstacles have to be carefully avoided,

driving smoothly and bending the vehicle as little as

possible.

Always use the turn indicators timely when you in-

tend to change lane or direction, avoiding sharp and

dangerous movements.

After the first 500 kilometres, carry out the

checking operations indicated in the column

"After running-in" of the PERIODIC MAINTE-

NANCE CHART, see p. 26, in order to avoid hurting

yourself or other people and/or damaging the vehi-

cle.

The running-in of the engine is primary to ensure its cor-

rect functioning 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.

For the first 500 km, keep to the following indications:

0-300 km

Do not keep the throttle grip open more than one half for

long stretches.

300-500 km

Do not keep the throttle grip open more than three-

fourths for long stretches.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

◆

Release the throttle grip and stop the vehicle by

putting on the brakes.

◆

Move the ignition switch to position "m".

It is not necessary to close the fuel tap when

the engine is off, since it is equipped with an

automatic closing system.

Park the vehicle on firm and flat ground, to

prevent it from falling down.

Neither lean the vehicle against walls, nor

lay it on the ground.

Make sure that the vehicle and especially its red-hot

parts do not represent a danger for persons and

children.

Do not leave the vehicle unattended when the en-

gine is on or the key is inserted into the ignition

switch.

Do not sit on the vehicle when the stand is down.

Seize the vehicle using the rear grab rail and at the

same time push the stand lever downwards (see figure).

Make sure that the vehicle is resting firmly.

This vehicle is provided with front hydraulic disc brake.

When the disc pads wear out, the level of the fluid de-

creases to automatically compensate for their wear.

Periodically check the brake fluid level in the tank and

the wear of the pads, see p. 18 (CHECKING THE PAD

WEAR).

The brakes are the parts that most ensure

your safety and for this reason they must al-

ways be perfectly working.

ADJUSTING THE BRAKE

◆

Measure the distance covered by the lever (9-Fig. 3)

before the brake starts it braking action.

The idle stroke at the end of the brake lever must be

about 5 ÷ 10 mm.

◆

Adjust the clearance by acting on the adjuster

(1-Fig. 15).

◆

Put on the brake (9-Fig. 3) repeatedly and make sure

that the wheel turns freely after the brake has been re-

leased.

◆

Check the braking efficiency.

For any doubt regarding the perfect func-

tioning of the braking system and in case

you are not able to carry out the usual

checking operations, contact your

Official

Dealer.

◆

Remove the two plastic elements (1) protecting the

stem.

◆

Unscrew the two screws (2) and remove the brake

caliper.

◆

Unscrew the nut (3).

Coppia di serraggio: 50 Nm (5 kgm).

◆

Slide the pin nut (5).

◆

Remove the wheel.

Upon reassembly position the odometer ca-

ble (4) correctly.

Adjust the play on the accelerator via the appropriate

tightener on the carburettor.

To access the carburattor:

◆

Remove the screw (1).

◆

Pull the tool-helmet, compartment after disconnecting

the compart- ment lighting cable.

Before carrying out the following opera-

tions, let the engine and the silencer cool

down until they reach room temperature, in

order to avoid burns.

◆

Position the vehicle on the centre stand.

◆

Unscrew and remove the two screws (1) and (2).

◆

Slacken the two screws that hold the exhaust silencer

to the cylinder (access through the battery compart-

ment)

◆

Remove the silencer (4).

Upon reassembly, change the exhaust man-

ifold-silencer seal.

◆

Put on the rear brake (9 - Fig. 3) to lock the wheel.

◆

Unscrew and remove the wheel nut (3) and the wash-

er.

Upon reassembly, change the wheel nut

(special type).

Wheel nut driving torque: 110 Nm (11 kgm).

◆

Withdraw the wheel.

Check the wear of the rear brake shoes after the first

500 km and successively every 4000 km.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

To check the wear of the rear brake shoes, proceed as

follows:

◆

Remove the rear wheel, see p. 17 (REMOVING THE

REAR WHEEL).

◆

To check the thickness of the friction material, which

must never be less than 1 mm (Fig. 19).

If the minimum allowed limit has been

reached, if you notice any irregularity in the

operation or if any part is damaged, contact

your

Official Dealer, who will provide for

changing the brake shoes.

Check the brake pad wear after the first 500 km and suc-

cessively every 2000 km.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

The wear of the brake pads depends on the use, on the

kind of drive and on the road. The wear will be greater

when the vehicle is driven on dirty or wet roads.

To carry out a rapid checking of the wear of the front

pads, proceed as follows:

◆

Position the vehicle on the centre stand.

◆

Remove the brake caliper cover.

◆

Carry out a visual checking of the friction material

thickness by looking between the brake caliper and

the pads.

If the thickness of the friction material (even of one pad

only) has reduced to about 1 mm, replace both pads.

Have the pads changed by your

Offi-

cial Dealer.

Grease the rear brake cam pin every 4000

km. If the vehicle is used on dusty roads,

this operation must be carried out more frequently.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

◆

Disassemble the rear wheel, see p. 17 (REMOVING

THE REAR WHEEL (Fig. 18)).

◆

Unscrew and remove the adjuster (1-Fig. 15).

Do not dirt the shoes and the friction materi-

al with grease, to avoid compromising the

braking efficiency of the vehicle.

This operation may be difficult because the

springs resist considerably to the removal

of the shoes. Be careful not to crush or

bruise your hands and fingers.

◆

Grasp the inner edge of the two friction elements (1)

at its centre and, pulling toward yourself, shake the

two shoes, thus releasing them.

◆

Loosen the nut (2) and remove the pin lever (3).

◆

Withdraw the cam pin (4).

Moderately grease only the central part of

the pin.

Avoid dirting the cam or the areas around

the pin seat with grease.

◆

Grease the central part of the pin by using grease for

kinematic motions, see p. 27 (LUBRICANT CHART).

Upon reassembly:

Neither strike, nor force the cam pin (4) with

hammers or others tools, in order not to

damage the two O-rings.

◆

Manually insert the cam pin (4), rotating and pushing it

slightly.

Make sure that the springs are correctly

coupled.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

Check the conditions of the air cleaner and clean it

monthly or every 4000 km, depending on the conditions

in which the vehicle is used.

If the vehicle is used on dusty or wet roads, the cleaning

operations and any replacement should be carried out

more frequently.

◆

Position the vehicle on the stand.

◆

To remove the left side panel of the vehicle.

◆

Unscrew the four screws.

◆

Remove the filter case cover and extract the filtering

element.

◆

To clean the filtering element use clean, non-inflam-

mable solvents or solvents with high volatility point,

then let it dry thoroughly.

◆

Apply a filter oil or a thick oil (SAE 80W-90) on the

whole surface of the filtering element, then squeeze it

to eliminate the oil in excess.

The filter must be well impregnated, though

not dripping.

Periodically remove the spark plug and clean it carefully,

removing carbon deposits; change it if necessary.

To remove and clean the spark plug:

◆

Remove the engine compartment cover.

◆

Take off the spark plug cap.

◆

Remove all the dirt from the base of the spark plug,

then unscrew it with the spanner you will find in the

tool kit and extract it from its seat, taking care that nei-

ther dust nor other substances enter the cylinder.

◆

Make sure that there are neither carbon deposits, nor

corrosion marks on the electrode and on the central

porcelain part; if necessary, clean them with the spe-

cial cleaners for spark plugs, with an iron wire and/ or

a metal brush.

◆

Energetically blow some air, in order to prevent the re-

moved residues from getting into the engine.

If the spark plug has crackings on the insulating mate-

rial, corroded electrodes or excessive deposits, it

must be changed.
