safe driving



BASIC SAFETY RULESThe instructions given below cover normaloperation of your vehicle and must becarefully observed. By following theserules you will enhance your own safety andthe safety of those around you. You willalso maximize the life and utility of yourvehicle.

Two wheeled vehicles obviously do notprovide some of the protection provided byautomobiles, therefore it is essential thatyou wear appropriate protective clothing.Especially, never operate your vehiclewithout wearing your helmet, gloves, eyeprotection, a heavy jacket, sturdy footwear,and sturdy full length pants. However, do not assume that even thebest clothing and helmet will protect you inthe event of an upset or a crash withanother vehicle. At best, this gear providessome protect ion f rom scrapes andscratches, but very little, if any, impactprotection.

Be sure that you meet all the requirementsprescribed by local law, including driver»slicense, minimum age, training, insurance,taxes, vehicle registration, license plate,etc.

When you first receive your vehicle,practice by riding in areas where there islittle traffic. Do not attempt to ride in heavytraffic until you are thoroughly experiencedand riding your vehicle has becomesecond nature to you.

Although this vehicle is legal for operationon freeways and expressways, i t isadvisable to not ride on these high speedhighways until you are thoroughly familiarwith your vehicle, and have attained a highdegree of skill in its operation.

A new vehicle must be carefully broken in,see p.54 (BREAKING-IN).

Before starting the engine, make sure thatthe brakes, clutch, transmission andthrottle controls function properly and thatthe fuel and oil supply is adequate.

The exhaust system, brakes, and someother parts of the vehicle become very hotduring operation. Do not touch any of theseparts.Some medicines or drugs, i l legal orprescription, and alcohol significantlyincrease the risk of accidents. Do not ridewhile you are under the influence ofa lcoho l o r d rugs , be they i l l i c i t o rprescription.

Make sure you are in good physicalcondition and not ill before riding yourvehicle. Do not ride your vehicle when youare particularly tired or fatigued. Alcohol,drugs and fatigue are leading causes ofvehicle accidents.

Many accidents are caused by the rider»sinexperience and lack of training. Do notride your vehicle until you have receivedtra in ing f rom a recognized t ra in ingorganization such as the Motorcycle SafetyFoundation. Remember that riding a twowheeled vehicle, though easy and fun, isquite different from driving a car. Do notassume that you can operate your vehiclesafely just because you are a competentautomobile driver.

Never lend your vehicle to others unlessyou are sure that they are competent andproperly licensed vehicle operators.



Observe all rules of the road. Particularlypay attention to all warning, regulatory andinformational signs.

Avoid showing off (i.e., popping wheelies).Especially observe speed limits, rememberthat road conditions change with theweather and wet and icy pavements arepart icularly dangerous for vehicles,especial ly i f you are riding too fast.Remember that automobile drivers have ahard time seeing two wheeled vehicles, soalways give the automobile the right ofway, even if it is legally yours.Before changing lanes, look over yourshoulder to make sure that the way isclear. Do not rely exclusively on the rear-view mirror: you may miscalculate thedistance and speed of a vehicle, or youmay even not see it at all.

Avoid obstacles that could damage thevehicle or make you lose control.

Do not tailgate, do not attempt to increaseyour gas mileage by following in the slipstream of cars or trucks in front of you.

In case of accident motorcycles, scootersand mopeds do not provide the samedegree o f p ro tec t ion ensured byautomobiles. The legs, in particular, areexposed the r isk o f be ing in ju red.However, the additional installation of legguards may actually increase the risk ofinjuries and their seriousness in case ofaccident.

Do not install leg guards available on themarket of spare parts and accessories.Non-compliance with these instructionsmay result in serious injuries or evendeath.

Always r ide with both hands on thehandlebars and feet on the footrests.

Never shift gear without using the clutch, ifthe vehicle is so equipped. Do not operatethe shif t lever or the other controlssuddenly or abruptly. Such misuse candamage the internal components of thevehicle and consequently cause seizure,loss of control, accidents and seriousinjuries or even death.Remain in the seat when you are riding. Donot stand up or attempt to stretch while youare riding your vehicle. If you need to rest,pull over to the side of the road when it canbe safely done.



It is very important to your safety that yougive full attention to the riding task. Watchwhat you are doing, do not allow yourself tobe distracted by other cars, people orthings on the roadside, etc. Never smoke,eat, drink, read, etc. while riding yourvehicle. If you must consult a map, pullover when it can be done safely.

Use only the vehicle»s specific fuels andlubricants indicated in the ≈LUBRICANTCHART∆; check the oil, fuel and coolantlevels regularly.

If the throttle sticks open, it may cause acollision with another vehicle, or an upset.

If the throttle sticks, kill the engine with theengine stop switch located on the righthandlebar.

Do not attempt to restart the engine untilthe throttle has been repaired and worksperfectly. Failure to obey this warning canlead to a runaway with seriously injuries oreven death.

WARNINGIn the event of a throttle stickingemergency, always kill the engine usingthe engine stop switch located near thethrottle grip on the right handlebar.Never use your vehicle if the throttledoes not automatically fully return tothe idle position when the throttle gripis released. Contact your Local apriliaDealer for repairs. Failure to heed thiswarning can lead to a serious accidentand subsequent injury or even death.

If you and your vehicle are involved in anaccident, insure that there has been nodamage to the control levers, tubes, wires,braking system and other vital parts. If yourvehicle is involved in an accident, take itimmediately to your Local aprilia Dealerwho has the equipment and knowledge tocheck for accidental damage which maycompromise your safety.

Your aprilia dealer is ready and able tohelp you with any safety problems that youmight have, but of course it is necessaryfor you to report any malfunctions to yourmechanic in order for him to help you.

Do not use your vehicle if it is damaged. Adamaged vehicle may become unstable orpresent other problems which can increasethe risk of accident, and therefore ofserious injury or even death.

COOLEROIL



Do not attempt to modify the position,angle or color of your license plate. Do notcover it with even a clear plastic covering.Do not modify any of the safety equipmentof your vehicle, especially such safetyrelated items as directional indicators, rearview mirrors, lights or horns.Any modification to your vehicle willinvalidate the warranty.

Do not modify your engine in an attempt toincrease the horsepower. This can result inirreparable damage to the engine, as wellas degradation of the performance andhandling of the vehicle which could lead toan upset, and serious injury or even death.

Have your vehicle repaired only withoriginal parts, and use only original apriliaor aprilia approved accessories. The useof aftermarket accessories and parts canseriously compromise the safety of yourvehicle as well as its performance andserviceability. Any modification whichaffects performance or safety voids yourwarranty completely.

Tampering with the emissions or noisecontrol systems on your vehicle is againstthe law, and can be punished by largefines.In some jurisdictions, it can even lead tothe confiscation of your vehicle.

This vehicle was not designed to beequipped with a sidecar or to be used totow trailers or other vehicles.

aprilia does not manufacture sidecars ortrailers and therefore cannot predict theef fects of such accessor ies on themanoeuvrability or stability of the vehicle: itcan only warn that such effects may benegative and that any damage to thevehicle components caused by the use ofsuch accessories will not be covered bythe warranty.

A12345

ONLY ORIGINALS



Never race other vehicles with yourvehicle.

Brake with both the front and rear brakes.The use of one brake only for suddenbraking may cause the vehicle to skid ormake the rider lose control of the vehicleitself.When riding down a steep hill, use theengine as a brake by selecting the samegear, or a lower gear, than you would useto climb the hill. Use front and rear brakessparingly.

Always ride at the appropriate speed andavoid unnecessary hard acceleration. Thisnot only is safer, but also reduces fuelconsumption and increases the life of thevehicle.

If you must ride your vehicle in rainyweather, or on loose surfaces, rememberthat traction is greatly reduced. Underthese conditions, all handling of the vehiclemust be done gradually and smoothly.Sudden acceleration, braking or turningmay make you lose control of your vehicle.When traction is reduced, accelerate andslow using your vehicle»s engine brakinginsofar as possible. Avoid rapid, harshapplication of the brakes.

Gradually open and close the throttle, toavoid spinning or skidding the rear wheel.

On rough road surfaces, slow down andride with particular care.Try to avo id w ide open th ro t t leaccelerations, unless they are necessaryfor such things as passing.Don»t allow your engine to ≈lug,∆ that is, runat too low an rpm. Shift down to a lowergear. Also, don»t over-rev the engine.Observe the redline on the tachometer.

Remember that excessively aggressivecornering can cause your vehicle»s tires tolose sideways traction, which can result inan upset and serious injury or even death.



Always observe posted and statutoryspeed limits, but do not assume that youcan ride as fast as the speed limit under allroad conditions. Slowing down a little cangreatly increase your safety under all roadconditions.

Do not ride your vehicle off road.Do not tamper with the muffler system orthe emissions control system of yourvehicle. This is not only bad for theenvironment, it can subject you to seriouspenalties.

CLOTHINGBefore riding your vehicle, ensure that yourriding gear is in good condition. To beeffective, your helmet must fit properly, andthe visor or other eye protection must beclean.

Both research and experience have shownthat drivers of other vehicles often do notsee vehicles or riders. In order to makeyourself more conspicuous to thesedrivers, wear bright reflective clothing,such as a reflective vest, or clothing withreflective sections sewn into the jacket,pants and gloves. Be particular aware ofapproaching automobiles and trucks thatmight be trying to turn left in front of you.Many vehicle accidents are caused by anopposing automobile driver making a leftturn without warning in front of the vehicle.

Inevitably, the driver will look right at you,and yet swear that they did not see youbefore they turned directly into your path.Ride alert!Wear protective clothing, preferably in lightand/or reflecting colors. In this way you willmake yourself more visible to the otherdrivers, thus notably reducing the risk ofbeing knocked down, and you will be moreprotected in case of fall.Always wear your crash helmet. Manyaccidents are fatal because of injuries tothe head.This clothing should be very tight-fittingand fastened at the wrists and ankles.Strings, belts and ties should not behanging loose; prevent these and otherobjects from interfering with driving bygetting entangled with moving parts ordriving mechanisms.



Do not carry sharp objects in your pocketsthat could be dangerous in case of anupset, for example, pens or mechanicalpencils, etc. Also, make sure that yourpassengers follow this recommendation.

ACCESSORIESThe owner of the vehicle is responsible forthe choice, installation and use of anyaccessory.

The ins ta l la t ion o f inappropr ia teaccessories or the overloading of thevehicle may result in the instability of thevehicle itself and cause accidents withconsequent risk of serious injuries or evendeath. Windshields could be particularlydangerous, as they can break and injure orcut the rider in case of accident. In case ofdoubts with regard to any accessory youwould like to install or any load you wouldlike to carry, previously consult your Localaprilia Dealer.

Avoid installing accessories that coverhorns or lights or that could impair theirfunctions, limit the suspension stroke andthe steering angle, hamper the operation ofthe controls and reduce the distance fromthe ground and the angle of inclination inturns.Avoid using accessories that hamperaccess to the controls, since this canpro long reac t ion t imes dur ing anemergency.

Fairings and windshields installed on thevehicle may produce aerodynamic forcesthat will affect the stability of the vehicleduring use, especially at high speeds.

Make sure that anything you carry on yourvehicle is securely attached, and cannotcome lose and jam the wheels, forks, etc.Do not install any electrical accessories,and do not modify the electrical system ofyour vehicle. Anything that could cause anelectrical overload or other fault couldcause the vehicle to suddenly stop, thelights to dim or quit, or the horn and othersafety accessories not to work. Use onlygenuine aprilia accessories.

LOADDo not overload your vehicle. Attachluggage or packages as close as possibleto the center of your vehicle and distributethe load from side to side as evenly aspossible, to keep imbalance to a minimum.Remember that loads tend to loosen withriding, so frequently check the security ofyour load.



Do not hang anything from your vehiclehandlebars, fenders, or forks, because thiswill upset the handling of your vehicle, andcould prevent you from avoiding anaccident. Failure to heed this warning canlead to an upset with subsequent seriousinjury or even death.Do not ride with your crash helmet hungfrom the strap because it could easily foulthe wheels, fenders, or forks, causing anupset and subsequent serious injury oreven death.

Carry a passenger only if your vehicle isequipped with passenger footrests,handgrips for the passenger to hold on to,and a passenger saddle.When carrying a passenger, rememberthat your vehicle»s handling is degraded,that the brakes are less efficient, and thecenter of gravity is higher and further to therear.

This makes it more likely that the frontwheel wi l l come up of f the ground,especially on acceleration. Therefore, youshould avoid hard acceleration and hardbraking. Many accidents are caused byinexperienced riders carrying passengers.Remember that allowance must be madefor the extra weight of the passenger for alldriving maneuvers.

Avoid abrupt and excessive acceleration.Always slow down in time and calculatelonger s topp ing and manoeuvr ingdistances. Non-compliance with theseinstructions may lead to the overturning ofthe vehicle or to other accidents withconsequent serious injuries or even death.

Never carry loosely packaged items, makesure that everything that you carry on yourvehicle is carefully secured.

Do not carry packages which protrude fromthe luggage rack or which cover any of thesignal lights, the headlight, or the horn.

Never carry animals or children on theglove compartment or on the luggage rack.

Never exceed the labeled maximum loadfor each saddlebag.Overloading your vehicle seriously reducesits stability and maneuverability and canlead to an upset with subsequent seriousinjury or death.

MAIN COMPONENTS

FUEL

WARNINGThe fuel used for internal combustionengines is extremely inflammable andin particular conditions it can becomeexplosive. It is important to carry outthe refuelling and the maintenanceoperations in a well-ventilated area,with the engine off. Do not smoke whilerefuelling or near fuel vapors, in anycase avoid any contact with nakedflames, sparks and any other heatsource to prevent the fuel from catchingfire or from exploding. Further, prevent fuel from flowing out ofthe fuel filler, as it could catch fire whengetting in contact with the red-hotsurfaces of the engine. In case some fuel has accidentally beenspi l t , make sure that the area iscompletely dry before starting thevehicle.Since petrol expands under the heat ofthe sun and due to the effects of sunradiation, never fill the tank to the brim. Screw the plug carefully after refilling.Avoid any contact of the fuel with theskin and the inhalation of vapors; donot swallow fuel or pour it from areceptacle into another by means of atube.

ALWAYS DISPOSE OF FUEL INCOMPLIANCE WITH ENVIRONMENTALREGULATIONS.

KEEP OUT OF REACH OF CHILDREN.

Use only un leaded gasol ine wi th aminimum octane rating of 91 (RON) or 81(MON).

To refuel, proceed as follows:◆ Lift the saddle, see page 43 (UNLOCKING

/ LOCKING THE SADDLE).◆ Unscrew and remove the fuel tank plug

(1).

FUEL TANK CAPACITY ( reserveincluded):

√ 2 US gal (7.5 )√ 2.1 US gal (8 )

FRONT DISC BRAKE

WARNINGThe brakes are the parts that mostensure your s a f e t y a n d f o r t h i sreason they must always be perfectlyworking; check them before every trip.

A dir ty disc soi ls the pads, withconsequent reduction of the brakingefficiency. Dirty pads must be replaced,while dirty discs must be cleaned with ahigh-quality degreaser.

The brake fluid must be changed everytwo years at an aprilia Official Dealer.


This vehicle is provided with front hydraulicdisc brake.

When the disc pads wear out, the level ofthe f luid decreases to automaticallycompensate for their wear.

The brake fluid reservoir (1) is positionednear the front brake lever coupl ing.Periodically check the brake fluid level inthe reservoir (1) and the pad wear, seepage 72 (CHECKING THE BRAKE PADWEAR).

WARNINGDo not use the vehicle if the brakingsystem leaks fluid.

CHECKINGTo check the brake fluid level, proceed asfollows:

NOTE Position the vehicle on firm andflat ground.

◆ Position the vehicle on the centre stand.◆ Rotate the handlebar, so that the fluid

contained in the brake reservoir isparallel to the ≈MIN∆ mark stamped onthe glass gauge (2).

◆ Make sure that the fluid contained in thereservoir exceeds the ≈MIN∆ markstamped on the glass gauge (2).

MIN = minimum level.

If the fluid does not reach at least the ≈MIN∆mark:

CAUTIONWhen the disc pads wear out, the levelof the fluid decreases progressively tocompensate for their wear.

◆ Check the brake pad wear, see seepage 72 (CHECKING THE BRAKE PADWEAR).

If the pads and / or the disc do not needreplacing:

◆ Contact an aprilia Official Dealer, whowill provide for topping up.

CAUTIONCheck the braking efficiency.

In case of excessive stroke of the brakelever or reduced efficiency of thebraking system, contact an apriliaOff ic ia l Dealer , s ince i t may benecessary to bleed the system.

REAR DRUM BRAKE

WARNINGThe brakes are the parts that mostensure your s a f e t y a n d f o r t h i sreason they must always be perfectlyworking; check them before every trip.


ADJUSTING THE BRAKE◆ Measure the distance covered by the

lever before the brake starts its brakingaction. The idle stroke at the end of thebrake lever must be about 0.4 in (10mm).

To adjust the clearance, proceed asfollows:

◆ Force the spring (1) to reach the seat (2)of the threaded rod.

◆ Lock the rotation of the threaded rod byacting on the appropriate seat (2) with aspanner.

◆ Act on the adjuster (3).◆ Put on the brake repeatedly and make

sure that the wheel turns freely after thebrake has been released.

◆ Check the braking efficiency.

The fact that the adjuster (3) can betightened completely or the indicator (4)is positioned beyond the referencetooth (5) indicates that the brake shoesare worn; in this case, see page 73(CHECKING THE BRAKE SHOE WEAR).

TYRESThis vehicle is provided with tubeless tires.

WARNINGPeriodically check the tire inflationpressure at room temperature, seepage 104 (TECHNICAL DATA).

If the tires are hot, the measurement isnot correct.Carry out the measurement especiallybefore and after long rides.

If the inflation pressure is too high, theground unevenness cannot bedampened and is therefore transmittedto the handlebar, thus compromisingthe driving comfort and reducing roadholding turns.

If, on the contrary, the inflation pressureis too low, the tire sides (1) are undergreater stress and the tire itself may slipon the rim or it may become loose, withconsequent loss of control of thevehicle.In case of sudden braking the tirescould even get out of the rims. Further, the vehicle could skid whileturning.

Check the surface and the wear of thetires, since tires in bad conditions canimpai r both the gr ip and thecontrollability of the vehicle.

Some types of tires homologated forthis vehicle are provided with wearindicators. There are several k inds of wearindicators. For more information on how to checkthe wear, contact your Dealer. Visually check if the tires are worn andin this case have them changed.

I f the t i res are hold , even i f notcompletely worn out, they may becomehard and may not ensure good roadholding. In this case, have the tires changed.

Change the tire when it is worn out or incase of puncture on the tread side, if thepuncture is larger than 5 mm.

After repairing a tire, have the wheelsbalanced.

Use only tires in the size suggested bythe Manufacturer , see page 104(TECHNICAL DATA).

Do not install tires with air tube on rimsfor tubeless tires, and viceversa.

Make sure that the tires always havetheir valve sealing caps (2) on, toprevent them from suddenly going flat.

Change, repair, maintenance andbalancing operations are very importantand should be carried out by qualifiedtechnicians with appropriate tools.For this reason, it is advisable to havethe above mentioned operations carriedout by an aprilia Official Dealer or by aqualified tire repairer.

If the tires are new, they may still becovered by a sl ippery f i lm: drivecarefully for the first miles. Do not oilthe tires with unsuitable fluids.

CATALYTIC SILENCERAvoid parking the vehicle catalyticversion near dry brush wood or inplaces easily accessible to children, asthe cata ly t ic s i lencer becomesextremely hot during use; be verycareful and avoid any kind of contactbefore it has completely cooled down.

The catalytic vehicle is fitted with a silencerwith metal catalytic converter of the≈platinum-rhodium bivalent∆ type.This device provides for the oxidation ofthe CO (carbon monoxide) and of the HC(unburned hydrocarbons) contained in theexhaust gases, changing them into carbondioxide and steam, respectively.

M50 MC50



Due to cata ly t ic react ion, the h ightemperature reached by the exhaust gasesmakes for the burning of the oil particles,thus keeping the si lencer clean andeliminating exhaust fumes.

To have the catalytic converter functioncorrectly and for long time and to reducepossible problems regarding the soiling ofthe thermal unit and of the exhaust, it isnecessary to avoid covering long distanceswith the engine running at constantly lowrpm.

It is sufficient to alternate these periodswith periods in which the engine runs atrelatively high rpm, even if only for a fewseconds, but rather frequently.What has been stated above assumesparticular importance for the cold startingof the engine: in this case, in order to reacha rpm regime sufficient to enable the≈priming∆ of the catalytic reaction, justmake sure that the temperature of thethermal unit has reached at least 122 °F(50 °C); which generally occurs a fewseconds after starting the engine.

CAUTIONDo not use leaded petrol, since itcauses the destruction of the catalyticconverter.

EXHAUST SILENCER

WARNINGTampering with the noise controlsystem is prohibited.

Owners are warned that the law mayprohibit:√ the removal or rendering inoperative by

any person, other than for purposes ofmaintenance, repair or replacement, ofany dev ice or e lement o f des ignincorporated into any new vehicle √ forthe purpose of noise control √ prior to itssale or delivery to the ultimate purchaseror while it is in use; and

√ the use of the vehicle after such deviceor element of design has been removedor rendered inoperative by any person.

Check the exhaust si lencer and thesilencer pipes, making sure that there areneither signs of rust nor holes, and that theexhaust system works effectively.If the noise produced by the exhaustsystem increases, immediately contactyour aprilia Official Dealer.

CAUTIONDo not move off quickly when theengine is cold. To reduce polluting emissions and fuelconsumption, warm up the engine byriding at a moderate speed for the firstfew kilometers.

◆ Do not accelerate and deceleraterepeatedly as this can lead to losingcontrol of the vehicle.

WARNINGWhen braking, operate both brakes foreven deceleration, with a gradualpressure on the brake levers.Using only the front or rear brakereduces braking performance, and maylock up a wheel and lose road holding.

If stopping on an uphill, deceleratecompletely and use the brake to holdthe vehicle stationary. Using the engine to hold the vehiclesteady can overheat the speed variator.

WARNINGBefore entering a curve, reduce yourspeed and brake, then ride through thecurve at constant speed or slightlyaccelerating; do not brake fully: this willvery likely lead to skidding.

Using the brakes continuously ondownhills can overheat the brake padsand reduce braking performance.Exploit engine compression by usingboth brakes intermittently. Do not ridedownhill with the engine off.

WARNINGOn a wet or slippery surface (snow, ice,mud, etc.), ride at a low speed, withoutsudden braking or turns which couldcause the vehicle to skid and fall over.

Pay attention to obstacles or variationsin the road surface.Loose surfaces, tracks, manholecovers, painted road signals, metalplates used on construction sites, allbecome slippery in the rain, and shouldbe approached with caution, drivingevenly and with the vehicle as uprightas possible.



WARNINGAlways indicate lane changes or turnswith the provided equipment and inadvance, and avoid sudden, potentiallydangerous manoeuvres.Switch off indicators immediately afterturning.

Take care when overtaking or beingovertaken. In the rain, the mist produced by largevehic les reduces v is ib i l i ty ; theturbulence produced by large vehiclescan cause loss of control of the vehicle.

CAUTIONNever drain the fuel tank, either partiallyor completely. This may cause damageto the inner components of the fueltank, or to other parts of the fuelsystem.Always ensure that the fuel filler cap iscorrectly closed.

WARNINGNever attempt to tow your vehicle withanother vehicle.

WARNINGWhile your vehicle is being transported,it must be kept in a vertical position,firmly tied down, and with the wheelsblocked.

Transport your vehicle in neutral gearonly.

Failure to heed this warning couldcause ser ious damage to thetransmission due to vibration of thetransport truck.

CAUTIONNever drain the fuel tank, either partiallyor completely. This may cause damageto the inner components of the fueltank, or to other parts of the fuelsystem. Always ensure that the fuel filler cap iscorrectly closed.



CLEANING

Clean your vehicle regularly. Your vehicle willlook better and work better if you keep itclean. You will find you will need to clean itmore frequently if it is used in the followingconditions:

√ Polluted areas (cities and industrial areas).√ Areas characterized by a high percentage

of salinity and humidity (sea areas, hot andhumid climates).

√ Particular conditions (use of salt and anti-ice chemical products on the roads duringthe winter).

◆ Do not allow contaminants such asindustrial dust, tar spots, dead insects, birddroppings, etc. to remain on the paintedportions of your vehicle. They will veryquickly etch into and damage the paint.

◆ Do not park your vehicle under trees, sincesome trees ooze resins that containchemicals which can damage the paint.

WARNINGAfter your vehicle has been washed, thebrake functioning will be temporarilyimpaired because of the wetness of thediscs and pads. Do not ride in trafficuntil after you have dried the brakes byrepeated braking from slow speed.

Always after washing your vehicle,carry out the preliminary checkingoperation, see p.49 (PRELIMINARYCHECKING OPERATIONS ).

CAUTIONTo clean the lights, use a spongesoaked with water and a neutra ldetergent , rubbing the sur facesdelicately and rinsing frequently withplenty of water.

Polish with silicone wax only after havingcarefully washed your vehicle.

Do not use polishing pastes on mattpaints.

Do not wash the vehicle in direct sunlight,especially during the summer, when thepaintwork is still warm, since if theshampoo dries before being rinsed away,it can damage the paint.

Do not use solvents or water hotter than40°C to clean the plastic components ofthe vehicle.

Never use a high pressure washer, asteam cleaner, or an air augmented waterjet to clean your vehicle, especially thewheel hubs, handlebar controls, brakereservoirs and cylinders, instruments,electrical components or exhaust silencer.

Such cleaning machinery will force waterinto critical portions of your vehicle,which could damage your vehiclethrough corrosion or short circuiting.

Do not use alcohol or gasoline orsolvents to clean the rubber parts, theplastic parts, and the saddle, use onlyclear water with a mild soap.

WARNINGDo not apply any protective coating to thesaddle, such coatings tend to make thesaddle too slippery.



To remove dirt and mud from the paintedsurfaces, use a low pressure water hose.Carefully wet the dirty parts and removemud and dirt with a soft car sponge. Youmay use proprietary car shampoos (2-4%parts of shampoo in clear water), to makethis easier.Carefully flush so that no dirt or girtremains on the paintwork, and dry with aclean chamois or clean terry towel.To clean the engine and other non-paintedparts, use a mild solvent and a bristlebrush, along with plenty of rags.

After washing the vehicle, always:

KEEP POLLUTING SUBSTANCES ANDCOMPONENTS AWAY FROMCHILDREN.

DISPOSE OF POLLUTINGSUBSTANCES AND COMPONENTSPROPERLY.

PERIODS OF EXTENDED STORAGECertain precautions must be taken toprevent the negative effects cause by notusing the vehicle.

In addition, make sure to carry out allrepairs and perform an overall checkbefore putting the vehicle away, sinceotherwise you may forget to do them later.Proceed as follows:

◆ Remove the spark plug, see page 72(SPARK PLUG).

◆ Pour a teaspoon (5 -10 cm3) of motor oilinto the cylinder.

NOTE NOTE Place a clean cloth on thecylinder near the spark plug seat, to protectit from any oil spatters.

◆ Set the ignition switch to " " and pressthe engine start button " " for a fewseconds, for distribute oil evenly over thecylinder surfaces.

◆ Remove the protective cloth.◆ Reassemble the spark plug.◆ Remove the battery, see page 74

(REMOVING THE BATTERY) and page73 (EXTENDED BATTERY STORAGE).

◆ Wash and dry the vehicle, see page 83(CLEANING).

◆ Spread wax over the painted surfaces.◆ Inflate the tires, see page 86

(TECHNICAL SPECIFICATIONS).◆ Arrange the vehicle so that both tires are

ra ised o f f the g round , us ing anappropriate support.

◆ Do not drain the fuel tank. However, ifavai lable, you may wish to add aproprietary fuel storage additive, availablefrom your Local apr i l ia Dealer orautomobile supply stores. Follow theinstructions on the container of the additive.

M50



NOTE Do not add more than therecommended amount of additive.

CAUTIONSome fuel additives may damage somecomponents of your fuel system. Checkwith your Local aprilia Dealer.◆ Place the vehicle in a cool, dry room, away

from direct sunlight, with minimumtemperature variations.

WARNINGBefore carrying out the followingoperations, let the engine and the exhaustsilencer cool down until they reach roomtemperature. Failure to observe thiswarning can lead to serious burns.◆ Place a plastic bag over the outlet pipe of

the muffler, and tape or tie it tight.◆ Cover the vehicle with an old sheet or a light

canvas, do not use a sheet of plastic orother waterproof material. This will causecondensation which will result in corrosion.

PUTTING THE VEHICLE BACK INTOSERVICE

NOTE Remove the plastic bag from theoutlet pipe of the muffler.

◆ Uncover and clean the vehicle, see page83 (CLEANING).

◆ Check the battery charge status, seepage 75 (BATTERY RECHARGING)and install it, see page 75 (BATTERYINSTALLATION).

◆ Fill the tank with fuel, see page 41(FUEL).

◆ Carry out the preliminary checks, seepage 49 (TABLE OF PRELIMINARYCHECKS).

WARNINGRide a few miles to test at moderatespeed and away from high-traffic areas.
