To drive the vehicle it is necessary to be in
possession of all the requirements pre-
scribed by law (drivin licence, minimum
a e, psychophysical ability, insurance,
state taxes, vehicle re istration, number
plate, etc.).
Gradually et to know the vehicle by driv-
in it first in areas with low traffic and/or pri-
vate areas.
The use of medicins, alcohol and dru s or
psychotropic substances notably increases
the risk of accidents.
Be sure that you are in ood psychophysi-
cal conditions and fit for drivin 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 be inners and,
in any case, make sure that the driver has
all the requirements for drivin .

7
use and maintenance Leonardo 125 - Leonardo 150 - Leonardo 250
Ri orously observe all road si ns and na-
tional and local road re ulations.
Avoid abrupt movements that can be dan-
erous for yourself and other people (for
example: rearin up on the back wheel,
speedin , etc.), and ive due consideration
to the road surface, visibility and other driv-
in conditions.
Avoid obstacles that could dama e the ve-
hicle or make you lose control.
Avoid ridin in the slipstream created by
precedin 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 drivin posture.
Avoid standin up or stretchin your limbs
while drivin .

COOLER
OIL
The driver should pay attention and avoid
distractions caused by people, thin s and
movements (never smoke, eat, drink, read,
etc.) while drivin .
Use only the vehicle’s specific fuels and lu-
bricants indicated in the "LUBRICANT
CHART"; check all oil, fuel and coolant lev-
els re ularly.
If the vehicle has been involved in an acci-
dent, make sure that no dama e has oc-
curred to the control levers, pipes, wires,
brakin system and vital parts.
If necessary, have the vehicle inspected by
an aprilia Official Dealer, who should care-
fully check the frame, handlebars, suspen-
sions, safety parts and all the devices that
you cannot check by yourself.
Always remember to report any malfunc-
tion to the technicians to help them in their
work.
Never use the vehicle when the amount of
dama e it has suffered endan ers your
safety.

ONLY ORIGINALS
Never chan e the position, inclination or
colour of: number plate, direction indica-
tors, li hts and horns.
Any modification of the vehicle will result in
the invalidity of the uarantee.
Any modification of the vehicle and/or the
removal of ori inal components can com-
promise vehicle performance levels and
safety or even make it ille al.
We recommend respectin all re ulations
and national and local provisions re ardin
the equipment of the vehicle.
In particular, avoid all modifications that in-
crease the vehicle’s performance levels or
alter its ori inal characteristics.
Never race with other vehicles.
Avoid off-road drivin .
#,/4().'
Before startin , always wear a correctly
fastened crash helmet. Make sure that it is
homolo ated, in ood shape, of the ri ht
size and that the visor is clean.
Wear protective clothin , preferably in li ht
and/or reflectin colours.
In this way you will make yourself more vis-
ible to the other drivers, thus notably re-
ducin the risk of bein knocked down, and
you will be more protected in case of fall.
This clothin should be very ti ht-fittin
and fastened at the wrists and ankles.
Strin s, belts and ties should not be han -
in loose; prevent these and other objects
from interferin with drivin by ettin en-
tan led with movin parts or drivin mech-
anisms.

Do not keep objects that can be dan erous
in case of fall, for example pointed objects
like keys, pens, lass vials etc. in your
pockets (the same recommendations also
apply to passen ers).
!##%33/2)%3
The owner of the vehicle is responsible for
the choice, installation and use of any ac-
cessory.
Avoid installin accessories that cover
horns or li hts or that could impair their
functions, limit the suspension stroke and
the steerin an le, hamper the operation of
the controls and reduce the distance from
the round and the an le of inclination in
turns.
Avoid usin accessories that hamper ac-
cess to the controls, since this can prolon
reaction times durin an emer ency.
Bi fairin s and windshields installed on
the vehicle may produce aerodynamic forc-
es that affect the stability of the vehicle, es-
pecially when ridin at hi h speed.
Make sure that the equipment is well fas-
tened to the vehicle and not dan erous
durin drivin . Do not install electrical de-
vices and do not modify those already ex-
istin to avoid electrical overloads, be-
cause the vehicle could suddenly stop or
there could be a dan erous current short-
a e in the horn and in the li hts.
aprilia recommends the use of "aprilia
enuine accessories".
,/!$
Be careful and moderate when loadin
your lu a e. Keep any lu a e loaded as
close as possible to the center of ravity of
the vehicle and distribute the load uniform-
ly on both sides, in order to reduce umbal-
ance to the minimum. Furthermore, make
sure that the load is firmly secured to the
vehicle, especially durin lon trips.
