APRILIA RX 50 - 2002 Bedienungsanleitung

ONLY FOR THE CATALYTIC VERSION

USE ONLY UNLEADED PETROL IN CONFORMITY WITH THE DIN 51607 STANDARD, MIN. O.N. 95

(N.O.R.M.) AND 85 (N.O.M.M.) AND HIGH PERFORMANCE SYNTHETIC OIL FOR 2 STROKE ENGINES.

THE USE OF FUELS AND LUBRICANTS DIFFERENT FROM THOSE INDICATED CAUSES SEVERE

FUNCTIONAL INCONVENIENCES TO THE VEHICLE AND THE VOIDING OF THE aprilia GUARANTEE.

ONLY FOR THE CATALYTIC VERSION

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 RX50 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 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.

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 identifi-

cation sticker comes off.

All information is purely indicative and may be sub-

ject to variation without notice.

Carefully observe the instructions preceded by the

following warning signs:

TYRE INFLATION PRESSURE

Maximum front and rear pressure: 2,5 bar

Low pressure can cause handling prob-

lems and the tendency to weave and in

extreme cases loss of control.

Moreover this will cause a great increase of roll-

ing friction.

The results are: high consumption of fuel and re-

duced maximum speed.

The disadvantage may cause a damage of the cover,

due to excessive local deformation.

Tyre pressure must be checked when the

tyres are at environment temperature,

that is, when the vehicle has not been moved in

the last 2 or 3 hours for more than 1 km.

Check the depth of the tyre tread often, if

it is worn below the allowable limit (2 -

3 mm.) change the tyre.

– The tyre should often be inspected for signs of

damage or cuts.

– Blowings or irregular wavings are showing in-

ternal damages, which request the prompt re-

placement of the tyre.

Remember: 1 mile = 1.6 km

1 km = 0.625 miles

IDENTIFICATION DATA

It is a good rule to write down the frame and engine

numbers in the space provided in this manual.

The frame number can be used for the purchase of

spare parts.

Do not alter the identification numbers if

you do not want to incur severe penal and

administrative sanctions. In particular, the altera-

tion of the frame number results in the immediate

invalidity of the guarantee.

FRAME NUMBER (Fig. 1)

The frame number is stamped on the left side of the

steering head.
