To have the catalytic converter functioning correctly for long periods and to reduce possible
problems regarding the contamination 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 importance 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, you just
need to make sure that the temperature of the thermal unit has reached at least 50°C, which generally
occurs a few seconds after starting the engine.

CATALYTIC SILENCER
The catalytic version of the MX50 is fittedwith asilencer with metal catalyticconverter of the “platinum-
rhodium bivalent” type. This device provides for the oxidation of the CO (carbon monoxide) and of the
HC (unburned hydrocarbons) 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
results in the burning of the oil particles, thus keeping the silencer clean and eliminating the exhaust
fumes.
Avoid parking the catalytic vehicle near dry brush wood or in places easily accessible to chil-
dren, as the catalytic silencer becomes extremely hot during use; be very careful and avoid any
kind of contact before it has completely cooled down.

This manual contains all the main information and the
instructions required for normal use and mainte-
nance of your vehicle.
For controls and check-ups that cannot be carried out
easily with the standard equipment supplied, we ad-
vise you to consult our Dealers who can assure you
of quick and careful servicing.
To keep your aprilia vehicle always in perfect operat-
ing conditions, we advise you to insist on Original
Spares and to have repairs carried out only by aprilia
Authorized Outlets and Official Dealers.
When ordering spare parts from the Dealers, 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 always have a record
of it even if the identification sticker comes off.
All information is purely indicative and may be sub-
ject to variation without notice.

BASIC SAFETY RULES
To drive the vehicle it is necessary to be in posses-
sion of all the requirements prescribed by law (driving
licence, minimum age, psychophysical ability, insu-
rance, 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.
The use of medicins, alcohol and drugs or psychotro-
pic substances notably increases the risk of acciden-
ts.
Be sure that you are in good psychophysical condi-
tions 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 ca-
se, 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 drive with both hands on the han-
dlebars and both feet on the footrests (or
on the rider’s footboards), in the correct
driving posture.
Avoid standing up or stretching your lim-
bs while driving.
The driver should pay attention and avoid distrac-
tions caused by people, things and movements (ne-
ver smoke, eat, drink, read, etc.) while driving.
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 le-
vers, pipes, wires, braking system and vital parts.
If necessary, have the vehicle inspected by an Con-
cessionario Ufficiale aprilia 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 te-
chnicians to help them in their work.
Never use the vehicle when the amount of dam-
age it has suffered endangers your safety.
Never change the position, inclination or colour of:
number plate, direction indicators, lights and horns.
Any modification of the vehicle will result in the invali-
dity of the guarantee.

Any modification of the vehicle and/or the removal of
original components can compromise vehicle perfor-
mance levels and safety or even make it illegal.
We recommend respecting all regulations and natio-
nal 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 cha-
racteristics.
Never race with other vehicles.
Avoid off-road driving.
CLOTHING
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 cle-
an.
Wear protective clothing, preferably in light and/or re-
flecting colours. In this way you will make yourself
more visible to the other drivers, thus notably redu-
cing the risk of being knocked down, and you will be
more protected in case of fall.
This clothing should be very tight-fitting and fas-
tened 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.

ACCESSORIES
The owner of the vehicle is responsible for the choi-
ce, installation and use of any accessory.
Avoid installing accessories that cover horns or lights
or that could impair their functions, limit the suspen-
sion stroke and the steering angle, hamper the ope-
ration 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 sta-
bility 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 genuine accessories
(aprilia genuine accessories).
