To dri e the ehicle it is necessary to be in
possession of all the requirements pre-
scribed by law (dri ing licence, minimum
age, psychophysical ability, insurance,
state taxes, ehicle registration, number
plate, etc.).
Gradually get to know the ehicle by dri -
ing it first in areas with low traffic and/or pri-
ate areas.
The use of medicins, alcohol and drugs or
psychotropic substances notably increases
the risk of accidents.
Be sure that you are in good psychophysi-
cal conditions and fit for dri ing and pay
particular attention to physical weariness
and drowsiness.
Most road accidents are caused by the
dri er’s lack of experience.
NEVER lend the ehicle to beginners and,
in any case, make sure that the dri er has
all the requirements for dri ing.

Rigorously obser e all road signs and na-
tional and local road regulations.
A oid abrupt mo ements that can be dan-
gerous for yourself and other people (for
example: rearing up on the back wheel,
speeding, etc.), and gi e due consideration
to the road surface, isibility and other dri -
ing conditions.
A oid obstacles that could damage the e-
hicle or make you lose control.
A oid riding in the slipstream created by
preceding ehicles 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 dri ing posture.
A oid standing up or stretching your limbs
while dri ing.

8use and maintenance Scarabeo 50 - Scarabeo 100
The dri er should pay attention and a oid
distractions caused by people, things and
mo ements (ne er smoke, eat, drink, read,
etc.) while dri ing.
Use only the ehicle’s specific fuels and lu-
bricants indicated in the "LUBRICANT
CHART"; check all oil, fuel and coolant le -
els regularly.
If the ehicle has been in ol ed in an acci-
dent, make sure that no damage has oc-
curred to the control le ers, pipes, wires,
braking system and ital parts.
If necessary, ha e the ehicle inspected by
an aprilia Official Dealer, who should care-
fully check the frame, handlebars, suspen-
sions, safety parts and all the de ices that
you cannot check by yourself.
Always remember to report any malfunc-
tion to the technicians to help them in their
work.
Ne er use the ehicle when the amount of
damage it has suffered endangers your
safety.
Ne er change the position, inclination or
colour of: number plate, direction indica-
tors, lights and horns.
Any modification of the ehicle will result in
the in alidity of the guarantee.
For only vehicles up to 50 cm3 included
Any modification of the engine or of other
members which is aimed at increasing the
speed or the power of the ehicle is prohib-
ited by the law; in fact, any modification re-
sulting in an increase of the maximum
speed or of the engine displacement would
change the scooter into a motorcycle,

which implies the following obligations for
the owner:
– new homologation;
– new registration;
– appropriate dri ing license.
Further, said modifications cause the loss
of the insurance co er, since insurance
policies expressly prohibit to make techni-
cal changes aimed at increasing the ehi-
cle performance le els.
For the reasons stated abo e, the failure to
comply with the tampering prohibition is
punished by law with appropriate sanctions
(including the confiscation of the ehicle),
which, according to the case, can be com-
bined with the sanctions pro ided for not
using the crash helmet and/or the number
plate, for the iolation of fiscal obligations
(ownership tax) and with penal sanctions
pro ided for using the ehicle without dri -
ing license.
For only vehicles over 50 cm3
Any modification of the ehicle and/or the
remo al of original components can com-
promise ehicle performance le els and
safety or e en make it illegal.
We recommend respecting all regulations
and national and local pro isions regarding
the equipment of the ehicle.
In particular, a oid all modifications that in-
crease the ehicle’s performance le els or
alter its original characteristics.
Ne er race with other ehicles.
A oid off-road dri ing.

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 isor is clean.
Wear protecti e clothing, preferably in light
and/or reflecting colours.
In this way you will make yourself more is-
ible to the other dri ers, thus notably re-
ducing the risk of being knocked down, and
you will be more protected in case of fall.
This clothing should be ery tight-fitting
and fastened at the wrists and ankles.
Strings, belts and ties should not be hang-
ing loose; pre ent these and other objects
from interfering with dri ing by getting en-
tangled with mo ing parts or dri ing mech-
anisms.

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

The owner of the ehicle is responsible for
the choice, installation and use of any ac-
cessory.
A oid installing accessories that co er
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.
A oid using accessories that hamper ac-
cess to the controls, since this can prolong
reaction times during an emergency.
Big fairings and windshields installed on
the ehicle may produce aerodynamic forc-
es that affect the stability of the ehicle, es-
pecially when riding at high speed.
Make sure that the equipment is well fas-
tened to the ehicle and not dangerous
during dri ing. Do not install electrical de-
ices and do not modify those already ex-
isting to a oid electrical o erloads, be-
cause the ehicle could suddenly stop or
there could be a dangerous current short-
age 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 gra ity of
the ehicle and distribute the load uniform-
ly on both sides, in order to reduce imbal-
ance to the minimum. Furthermore, make
sure that the load is firmly secured to the
ehicle, especially during long trips.

A oid hanging bulky, hea y and/or danger-
ous objects on the handlebars, mudguards
and forks: the ehicle might respond more
slowly in turns and its manoeu rability
could be una oidably impaired.
Do not place bags that are too bulky on the
ehicle sides, because they could hit peo-
ple or obstacles, making you lose control of
the ehicle.
Do not carry any bag if it is not tightly se-
cured to the ehicle.
Do not carry bags which protrude too much
from the luggage-rack or which co er the
lights, horn or indicators.
Do not carry animals or children on the
glo e compartment or on the luggage-
rack.
Do not exceed the maximum load allowed
for each side-bag.
When the ehicle is o erloaded, its stability
and its manoeu rability can be compro-
mised.
