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 uthor-
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.
ll information is purely indicative and may be subject to
variation without notice.

The catalytic mico 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.

◆Position the vehicle on the stand.
◆Lock at least one wheel, by pulling a brake lever (Fig.

ceives no current and therefore the engine does not
start.
