To drive the vehicle it is necessary to be in
possession of all the requirements pre­scribed by law (driving licence, minimum
age, psychophysical ability, insurance,
state taxes, vehicle registration, number
plate, etc.).

Gradually get to know the vehicle by driv­ing it first in areas with low traffic and/or pri­vate areas.

use and maintenance Leonardo 125 - Leonardo 150 - Leonardo 250

6

The use of medicins, alcohol and drugs or
psychotropic substances notably increases
the risk of accidents.

Be sure that you are in good psychophysi­cal conditions and fit for driving and pay
particular attention to physical weariness
and drowsiness.

Most road accidents are caused by the
driver’s lack of experience.

NEVER lend the vehicle to beginners and,
in any case, make sure that the driver has
all the requirements for driving.

Rigorously observe all road signs and na­tional and local road regulations.

Avoid abrupt movements that can be dan­gerous for yourself and other people (for
example: rearing up on the back wheel,
speeding, etc.), and give due consideration
to the road surface, visibility and other driv­ing conditions.

Avoid obstacles that could damage the ve­hicle or make you lose control.

Avoid riding in the slipstream created by
preceding vehicles in order to increase
your speed.

Always keep both hands on the handlebars
and both feet on the footboard (or on the
footrests), in the correct driving posture.

Avoid standing up or stretching your limbs
while driving.

The driver should pay attention and avoid
distractions caused by people, things and
movements (never smoke, eat, drink, read,
etc.) while driving.

use and maintenance Leonardo 125 - Leonardo 150 - Leonardo 250

Use only the vehicle’s specific fuels and lu­bricants indicated in the "LUBRICANT
CHART"; check all oil, fuel and coolant lev­els regularly.

If the vehicle has been involved in an acci­dent, make sure that no damage has oc­curred to the control levers, pipes, wires,
braking system and vital parts.
If necessary, have the vehicle inspected by
an aprilia Official Dealer, who should care­fully check the frame, handlebars, suspen­sions, safety parts and all the devices that
you cannot check by yourself.

Always remember to report any malfunc­tion to the technicians to help them in their
work.

Never use the vehicle when the amount of
damage it has suffered endangers your
safety.

ONLY ORIGINALS

Never change the position, inclination or
colour of: number plate, direction indica­tors, lights and horns.

Any modification of the vehicle will result in
the invalidity of the guarantee.

Any modification of the vehicle and/or the
removal of original components can com­promise vehicle performance levels and
safety or even make it illegal.

We recommend respecting all regulations
and national and local provisions regarding
the equipment of the vehicle.

In particular, avoid all modifications that in­crease the vehicle’s performance levels or
alter its original characteristics.

Never race with other vehicles.
Avoid off-road driving.

Before starting, always wear a correctly
fastened crash helmet. Make sure that it is
homologated, in good shape, of the right
size and that the visor is clean.

Wear protective clothing, preferably in light
and/or reflecting colours.
In this way you will make yourself more vis­ible to the other drivers, thus notably re­ducing the risk of being knocked down, and
you will be more protected in case of fall.

This clothing should be very tight-fitting
and fastened at the wrists and ankles.
Strings, belts and ties should not be hang­ing loose; prevent these and other objects
from interfering with driving by getting en­tangled with moving parts or driving mech­anisms.

9

Do not keep objects that can be dangerous
in case of fall, for example pointed objects
like keys, pens, glass vials etc. in your
pockets (the same recommendations also
apply to passengers).

The owner of the vehicle is responsible for
the choice, installation and use of any ac­cessory.

Avoid installing accessories that cover
horns or lights or that could impair their
functions, limit the suspension stroke and
the steering angle, hamper the operation of
the controls and reduce the distance from
the ground and the angle of inclination in
turns.

Avoid using accessories that hamper ac­cess to the controls, since this can prolong
reaction times during an emergency.

Big fairings and windshields installed on
the vehicle may produce aerodynamic forc­es that affect the stability of the vehicle, es­pecially when riding at high speed.

Make sure that the equipment is well fas­tened to the vehicle and not dangerous
during driving. Do not install electrical de­vices and do not modify those already ex­isting to avoid electrical overloads, be­cause the vehicle could suddenly stop or
there could be a dangerous current short­age in the horn and in the lights.
aprilia recommends the use of "aprilia
genuine accessories".

,/!$

Be careful and moderate when loading
your luggage. Keep any luggage loaded as
close as possible to the center of gravity of
the vehicle and distribute the load uniform­ly on both sides, in order to reduce umbal­ance to the minimum. Furthermore, make
sure that the load is firmly secured to the
vehicle, especially during long trips.

KG!

Avoid hanging bulky, heavy and/or danger­ous objects on the handlebars, mudguards
and forks: the vehicle might respond more
slowly in turns and its manoeuvrability
could be unavoidably impaired.

Do not place bags that are too bulky on the
vehicle sides, because they could hit peo­ple or obstacles, making you lose control of
the vehicle.

Do not carry any bag if it is not tightly se­cured to the vehicle.

Do not carry bags which protrude too much
from the luggage-rack or which cover the
lights, horn or indicators.

Do not carry animals or children on the
glove compartment or on the luggage­rack.

use and maintenance Leonardo 125 - Leonardo 150 - Leonardo 250

Do not exceed the maximum load allowed
for each side-bag.

When the vehicle is overloaded, its stability
and its manoeuvrability can be compro­mised.

aWARNING

The fuel used for internal combustion
engines is extremely inflammable and
in particular conditions it can become
explosive. It is important to carry out
the refuelling and the maintenance op­erations in a well-ventilated area, with
the engine off. Do not smoke while refu­elling or near fuel vapours, in any case
avoid any contact with naked flames,
sparks and any other heat source to
prevent the fuel from catching fire or
from exploding. Further, prevent fuel
from flowing out of the fuel filler, as it
could catch fire when getting in contact
with the red-hot surfaces of the engine.
In case some fuel has accidentally been
spilt, make sure that the area is com­pletely dry before starting the vehicle.
Since petrol expands under the heat of
the sun and due to the effects of sun ra­diation, never fill the tank to the brim.
Screw the cap carefully after refuelling.
Avoid any contact of the fuel with the
skin and the inhalation of vapours; do
not swallow fuel or pour it from a recep­tacle into another by means of a tube.

aWARNING

Pay special attention to the brake disc
and friction material, making sure that
they are neither dirty nor oily, especially
after maintenance operations or inspec­tions.

Make sure that the brake pipe is neither
twisted nor worn out.

KEEP AWAY FROM CHILDREN.

DO NOT DISPOSE OF THE FLUID IN
THE ENVIRONMENT.

$)3#"2!+%3

aWARNING

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 high­quality degreaser.

The brake fluid must be changed every
two years by an APRILIA Official Dealer.

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 reservoirs are positioned under
the handlebar cover, near the brake lever
couplings.

Periodically check the brake fluid level in
the reservoirs, see beside (CHECKING)
and the wear of the pads, see p. 48
(CHECKING THE BRAKE PAD WEAR).

aWARNING

Do not use the vehicle if the braking
system leaks fluid.

CHECKING

To check the brake fluid level, proceed as
follows:

NOTE Position the vehicle on firm and

flat ground.

◆

Position the vehicle on the centre stand.

◆

 + Remove the rear-view mirrors,

see p. 53 (REMOVING THE REAR­VIEW MIRRORS).

◆

Ì Move the rubber heat protection

screen (1) downwards.

◆

Rotate the handlebar, so that the fluid
contained in the brake reservoir is paral­lel to the “MIN” mark stamped on the
glass gauge (2).

◆

Make sure that the fluid contained in the
reservoir exceeds the "MIN" mark
stamped on the glass gauge (2).

MIN = minimum level.

If the fluid does not reach at least the "MIN"
mark:

aCAUTION

When the disc pads wear out, the level
of the fluid decreases progressively to
compensate for their wear.

◆

Check the brake pad wear, see p. 48
(CHECKING THE BRAKE PAD WEAR)
and the disc wear.

If the pads and/or the disc do not need re­placing:

◆

Contact an aprilia Official Dealer, who
will provide for topping up.

aCAUTION

Check the braking efficiency.

In case of excessive stroke of the brake
lever or reduced efficiency of the brak­ing system, contact an APRILIA Official
Dealer, since it may be necessary to
bleed the system.

aCAUTION

Do not use the vehicle if the coolant is
below the minimum prescribed level
“MIN”.

Check the coolant level every 2000 km
(1250 mi) and after long trips; have the
coolant changed by an aprilia Official
Dealer every 2 years.

aWARNING

The coolant is noxious: do not swallow
it; if the coolant gets in contact with the
skin or the eyes, it can cause serious ir­ritations.

If the coolant gets in contact with your
skin or eyes, rinse with plenty of water
and consult a doctor. If it is swallowed,
induce vomit, rinse mouth and throat
with plenty of water and consult a doc­tor without delay.

DO NOT DISPOSE OF THE FLUID IN
THE ENVIRONMENT.

KEEP AWAY FROM CHILDREN.

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.

Have the coolant changed by an APRILIA
Official Dealer.

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 to damage the engine.

aWARNING

Do not remove the expansion tank plug
(1) when the engine is hot, since the
coolant is under pressure and its tem­perature is high.
If it gets in contact with the skin or with
clothes it may cause severe burns
and/or damage.

CHECKING AND TOPPING UP

aWARNING

Check the coolant level and top up the
expansion tank with cold engine.

◆

Stop the engine and wait until it has

cooled down.

NOTE Position the vehicle on firm and

flat ground.

◆

Remove the front cover, see p. 53 (RE-

MOVING THE FRONT COVER).

◆

Make sure that the level of the fluid con-

tained in the expansion tank (2) is includ-

ed between the "MIN" and "MAX"

marks.

MIN = minimum level.
MAX= maximum level.

If not, proceed as follows:

◆

Loosen the filling cap (1) (by giving it two
anticlockwise turns), without removing it.

◆

Wait a few seconds in order to release
any residual pressure.

NOTE A breather pipe (3) is connected

to the cap (1). Neither force, nor discon­nect the breather pipe (3).

◆

Unscrew and remove the cap (1).

aWARNING

The coolant is noxious: do not swallow
it; if the coolant gets in contact with the
skin or the eyes, it can cause serious ir­ritations.
Do not use your fingers or any other ob­ject to check if there is enough coolant.

aCAUTION

While topping up, never exceed the
"MAX" level, otherwise the fluid will
flow out of the tank while the engine is
running.

◆

Top up with coolant, see p. 72 (LUBRI­CANT CHART) until reaching approx.
the "MAX" notch

◆

Put back the filling cap (1).

aCAUTION

In case of excessive consumption of
coolant and in case the tank remains
empty, make sure that there are no
leaks in the circuit.
Have it repaired by an APRILIA Official
Dealer.

This vehicle is provided with tubeless tyres.

aWARNING

Periodically check the tyre inflation
pressure at room temperature, see p. 68
(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.

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.
For more information on how to check
the wear, contact your Dealer.
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.

After repairing a tyre, have the wheels
balanced.

Use only tyres in the size suggested by
APRILIA, see p. 68 (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.

For this reason, it is advisable to have
the above mentioned operations carried
out by an APRILIA Official Dealer or by a
qualified tyre repairer.

If the tyres are new, they may still be
covered with a slippery film: drive care­fully for the first miles. Do not oil the

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 conse­quently losing grip.

The use of the engine to keep the vehi­cle at a halt may cause the overheating
of the speed variator.

Before beginning to turn, slow down or
brake driving 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 mate­rial may overheat, thus reducing the
braking efficiency.
Exploit the engine compression by
putting on both brakes intermittently.
Never drive downhill with the engine
off!

In case of wet road or scarce wheel grip
(snow, ice, mud, etc.), drive slowly,
avoiding sudden brakings or manoeu­vres that could make you lose grip and
fall down.

Pay the utmost attention to any obsta­cle or variation of the road surface.
Uneven roads, rails, manhole covers,
indications painted on the road surface,
building site metal plates become rather
slippery by rain. For this reason all
these obstacles have to be carefully
avoided, driving smoothly and bending
the vehicle as little as possible.

aWARNING

Always use the direction indicators in
time when you intend to change lane or
direction, avoiding sharp and danger­ous movements.
Switch off the direction indicators as
soon as you have changed direction.

Be extremely careful when you overtake
other vehicles or are overtaken.

In case of rain, the water cloud created
by big vehicles reduces visibility; the
air shift may make you lose control of
the vehicle.

aWARNING

After the first 1000 km (625 mi), carry
out the checking operations indicated
in the column "After running-in" of the
Regular Service Intervals Chart, see
p. 40 – 42 (REGULAR SERVICE INTER­VALS CHART), in order to avoid hurting
yourself 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 500 km (312

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 1000 km (625 mi), progres­sively increase the speed until reaching
the highest performance levels.

aWARNING

If possible, avoid stopping abruptly,
slowing down suddenly and braking at
the last moment.

In case of a brief stop, keep at least one

brake on.

Risk of fire.
Keep fuel and other flammable sub­stances away from the electrical com­ponents.

Before beginning any maintenance op­eration or any inspection of the vehicle,
stop the engine, extract the key from
the ignition block, wait until the engine
and the exhaust system have cooled
down and if possible lift the vehicle by
means of the proper equipment, on firm
and flat ground.

Before proceeding, make sure that the
room in which you are working is prop­erly ventilated.

Keep away from the red-hot parts of the
engine and of the exhaust system, in or­der to avoid burns.
Do not hold any mechanical piece or oth­er parts of the vehicle with your mouth:
the components are not edible and some
of them are noxious or even toxic.

aCAUTION

If not expressly indicated otherwise, for
the reassembly of the units repeat the
disassembly operations in reverse or­der.

In case any maintenance operation has
to be carried out, it is advisable to use
latex gloves.

Normally, the routine maintenance opera­tions can be performed by the user; how­ever, in some cases the use of specific
tools and technical expertise may be re­quired.

If you need assistance or technical advice,
consult your aprilia Official Dealer, who
can ensure you prompt and accurate serv­icing.

Ask your aprilia Official Dealer to test the
vehicle on the road after a repair or period­ic maintenance operation.
In any case, personally carry out the “Pre­liminary checking operations” after any
maintenance operation, see p. 32 (PRE­LIMINARY CHECKING OPERATIONS).
