GENERAL SAFETY RULE

CARBON MONOXIDE

If it is necessary to run the engine in order to carry out maintenance operation, make sure that the area in which you are operating is properly ventilated. Never run the engine in enclosed spaces.
If it is necessary to work indoors, use an exhaust evacuation system.
WARNING
The exhaust fumes contain carbon monoxide, a poisonous gas that can cause loss of consciousness and even death.
WARNING
Carbon monoxide is both colorless and odorless, and cannot be detected by smell, vision, or any other sense. Avoid breathing exhaust fumes under any circumstances.
GASOLINE
Keep gasoline away from children. Gasoline is also poisonous. Never attempt to siphon gasoline using your mouth. Never allow gasoline to contact your skin. If you should accidentally spill gasoline on yourself, change your clothes immediately and wash the area upon which the gasoline was splashed thoroughly with hot water and soap. Should you accidentally swallow gasoline, do not induce vomiting. Drink large quantities of clear water or milk and immediately seek professional medical assistance. Should you
accidentally get gasoline get your eyes, flush with large quantities of cool, clear water and immediately seek professional medical assistance.
WARNING
Gasoline is extremely flammable and becomes explosive under certain conditions.
KEEP GASOLINE AWAY FROM CHILDREN.

HOT COMPONENTS

WARNING
The engine and all parts of the exhaust system, as well as the braking system, become very hot and remain hot for some time after the vehicle and the engine are stopped. Before handling any component of your vehicle after riding, make sure that it has cooled sufficiently to be safe to handle.

USED ENGINE OIL

WARNING
Use latex gloves for maintenance operations that require contact with used oil. Used engine oil may cause skin cancer if repeatedly left in contact with the skin for prolonged periods. Although this is unlikely unless you handle used oil on a daily basis, it is advisable to thoroughly wash your hands with soap and water after handling used oil.
KEEP OIL AWAY FROM CHILDREN.

BRAKE FLUID

WARNING
Brake fluid is extremely poisonous. Do not ever allow brake fluid to be ingested or swallowed. Should brake fluid accidentally be swallowed, drink large quantities of milk or clear water and immediately seek professional medical assistance. Brake fluid is highly destructive of skin and eye tissue. Should you accidentally spill brake fluid on yourself, remove the contaminated clothing, wash your body with soap and warm water immediately and immediately seek professional medical assistance. Should you accidentally splash brake fluid into your eyes, flush with a large quantity of cool, clear water and immediately seek professional medical assistance.
KEEP BRAKE FLUID AWAY FROM CHILDREN.

COOLANT

In certain conditions, the ethylene glycol contained in the engine coolant is flammable: its flame is invisible, but you can be burned anyway.
WARNING
Avoid spilling the engine coolant on the exhaust system or on the engine components. They may be hot enough to cause the coolant to ignite and burn without a visible flame. The coolant (ethylene glycol) can cause skin irritation and is poisonous if swallowed. Coolant and coolant/water mixtures are sweet to the taste and brightly colored, therefore are highly attractive to pets and children. Take extra precautions to keep new and used coolant out of reach of children and animals.
KEEP COOLANT AWAY FROM CHILDREN.
Risk of burns. Do not remove the radiator cap when the engine is hot. Wait until the engine has completely cooled down. The coolant is under pressure and may splash out and cause burns.

BATTERY HYDROGEN GAS AND ELECTROLYTE

WARNING
The battery gives off noxious and explosive gases; keep cigarettes, flames and sparks away from the battery. Provide adequate ventilation when operating or recharging the battery.
During recharging and use, make sure that the room is properly ventilated and avoid inhaling the gases released during the recharging.
The battery contains sulfuric acid (electrolyte). Contact with the skin or eyes may cause serious burns. Always wear protective clothing, rubber gloves, and tight fitting goggles or a face shield when working around the battery, especially when filling the battery with either water or electrolyte.
In case of contact with the skin, flush immediately with plenty of water. In case of contact with the eyes, flush with plenty of water for at least 15 minutes. Immediately consult a health professional.
The electrolyte is poisonous. If the electrolyte is accidentally
swallowed, drink large quantities of water or milk and then milk of magnesia or vegetable oil. Immediately consult a health professional.
KEEP BATTERIES AND ELECTROLYTE AWAY FROM CHILDREN.

WARNING - PRECAUTIONS ­GENERAL ADVICE
Before starting the engine, read this manual carefully, and in particular the chapters WARNINGS - PRECAUTIONS - GENERAL ADVICE and SAFE DRIVE∆ see p. 19.
Your safety and that of those around you depends not only on your skill as a rider, but also your knowledge about your vehicle and about riding safely. Therefore it is essential that you not operate your vehicle on public streets or highways until you have received instructions from a qualified safety organization such as the Motorcycle Safety Foundation, and are properly trained and licensed.

REPORTING OF DEFECTS THAT AFFECT SAFETY

If you have any questions regarding your warranty rights and responsibilities, you should contact Piaggio Group Americas, Inc., 140 East 45th Street, 17th Floor New York, NY 10017, or the U.S. Enviromental Protection Agency, 2000 Traverwood Ann Arbor, MI 48105, or the California Air Resources Board at P.O. Box 8001, 9528 Telstar Avenue, El Monte, CA 91734-8001.
If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying aprilia. If NHTSA receives similar
complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or aprilia. To contact NHTSA, you may either call the Auto Safety Hotline toll free at 1-800-424-9393 (or 366-0123 in the Washington, D.C. area) or write to: NHTSA, U.S. Department of Transportation, Washington, D.C. 20590.
You can also obtain other information about motor vehicle safety from the Hotline.

ROAD REGULATIONS AND USE OF THE VEHICLE

Rules of the road vary from country to country. It is essential that you understand in advance the rules of the road of the country in which your vehicle will be used.
WARNING
This vehicle has been designed and produced for use only on paved roads. It is not designed to be used on even smooth graded dirt roads, or trails. It is not designed for off road competition, or for cross country riding. Do not use this vehicle on rough or unimproved surfaces, or in other off road areas. Failure to heed this warning could lead to an upset with subsequent injury and even death.

NOISE EMISSION WARRANTY

aprilia s.p.a. warrants that this exhaust system, at the time of sale, meets all applicable U.S. EPA Federal noise standards. This warranty extends to the first person who buys this exhaust system for purposes other than resale, and to all subsequent buyers.
Warranty claims should be directed to:
Piaggio Group Americas, Inc.
140 East 45th Street, 17th Floor New York, NY 10017 U.S.A.

INFORMATION ON THE NOISE AND EXHAUST GAS EMISSION CONTROL SYSTEM

ORIGIN OF THE EMISSIONS The combustion process produces
carbon monoxide and hydrocarbons. The control of hydrocarbons is very important, because under certain conditions they react to exposure to sunlight and produce photochemical smog. Carbon monoxide does not react in the same way, but it is toxic and poisonous. aprilia utilizes “lean” carburetor settings and other systems to reduce the production of carbon monoxide and hydrocarbons.

BASIC SAFETY RULES

The instructions given below cover normal operation of your vehicle and must be carefully observed. By following these rules you will enhance your own safety and the safety of those around you. You will also maximize the life and utility of your vehicle.
Two wheeled vehicles obviously do not provide some of the protection provided by automobiles, therefore it is essential that you wear appropriate protective clothing. Especially, never operate your vehicle without wearing your helmet, gloves, eye protection, a heavy jacket, sturdy footwear, and sturdy full length pants.
However, do not assume that even the best clothing and helmet will protect you in the event of an upset or a crash with another vehicle. At best, this gear provides some protection from scrapes and scratches, but very little, if any, impact protection.
Be sure that you meet all the requirements prescribed by local law, including driver»s license, minimum age, training, insurance, taxes, vehicle registration, license plate, etc.
When you first receive your vehicle, practice by riding in areas where there is little traffic. Do not attempt to ride in heavy traffic until you are thoroughly experienced and riding your vehicle has become second nature to you.
Although this vehicle is legal for operation on freeways and expressways, it is advisable to not ride on these high speed highways until you are thoroughly familiar with your vehicle, and have attained a high degree of skill in its operation.
A new vehicle must be carefully broken in, see p.54 (BREAKING-IN).
Before starting the engine, make sure that the brakes, clutch, transmission and throttle controls function properly and that the fuel and oil supply is adequate.
The exhaust system, brakes, and some other parts of the vehicle become very hot during operation. Do not touch any of these parts.
Some medicines or drugs, illegal or prescription, and alcohol significantly increase the risk of accidents. Do not ride while you are under the influence of alcohol or drugs, be they illicit or prescription.
Make sure you are in good physical condition and not ill before riding your vehicle. Do not ride your vehicle when you are particularly tired or fatigued. Alcohol, drugs and fatigue are leading causes of vehicle accidents.
Many accidents are caused by the rider»s inexperience and lack of training. Do not ride your vehicle until you have received training from a recognized training organization such as the Motorcycle Safety Foundation. Remember that riding a two wheeled vehicle, though easy and fun, is quite different from driving a car. Do not assume that you can operate your vehicle safely just because you are a competent automobile driver.
Never lend your vehicle to others unless you are sure that they are competent and properly licensed vehicle operators.

APRum_MOJ50_150#02_####.book Page 23 Tuesday, June 6, 2006 5:29 PM
Observe all rules of the road. Particularly pay attention to all warning, regulatory and informational signs.
Avoid showing off (i.e., popping wheelies). Especially observe speed limits, remember that road conditions change with the weather and wet and icy pavements are particularly dangerous for vehicles, especially if you are riding too fast. Remember that automobile drivers have a hard time seeing two wheeled vehicles, so always give the automobile the right of way, even if it is legally yours.
Before changing lanes, look over your shoulder to make sure that the way is clear. Do not rely exclusively on the rear­view mirror: you may miscalculate the distance and speed of a vehicle, or you may even not see it at all.
Avoid obstacles that could damage the vehicle or make you lose control.
Do not tailgate, do not attempt to increase your gas mileage by following in the slip stream of cars or trucks in front of you.
In case of accident motorcycles, scooters and mopeds do not provide the same degree of protection ensured by automobiles. The legs, in particular, are exposed the risk of being injured. However, the additional installation of leg guards may actually increase the risk of injuries and their seriousness in case of accident.
Do not install leg guards available on the market of spare parts and accessories. Non-compliance with these instructions may result in serious injuries or even death.
Always ride with both hands on the handlebars and feet on the footrests.
Never shift gear without using the clutch, if the vehicle is so equipped. Do not operate the shift lever or the other controls suddenly or abruptly. Such misuse can damage the internal components of the vehicle and consequently cause seizure, loss of control, accidents and serious injuries or even death.
Remain in the seat when you are riding. Do not stand up or attempt to stretch while you are riding your vehicle. If you need to rest, pull over to the side of the road when it can be safely done.

COOLER
OIL
It is very important to your safety that you give full attention to the riding task. Watch what you are doing, do not allow yourself to be distracted by other cars, people or things on the roadside, etc. Never smoke, eat, drink, read, etc. while riding your vehicle. If you must consult a map, pull over when it can be done safely.
Use only the vehicle»s specific fuels and lubricants indicated in the ≈LUBRICANT CHART; check the oil, fuel and coolant levels regularly.
If the throttle sticks open, it may cause a collision with another vehicle, or an upset.
If the throttle sticks, kill the engine with the engine stop switch located on the right handlebar.
Do not attempt to restart the engine until the throttle has been repaired and works perfectly. Failure to obey this warning can lead to a runaway with seriously injuries or even death.

WARNING
In the event of a throttle sticking emergency, always kill the engine using the engine stop switch located near the throttle grip on the right handlebar. Never use your vehicle if the throttle does not automatically fully return to the idle position when the throttle grip is released. Contact your Local aprilia Dealer for repairs. Failure to heed this warning can lead to a serious accident and subsequent injury or even death.
If you and your vehicle are involved in an accident, insure that there has been no damage to the control levers, tubes, wires, braking system and other vital parts. If your vehicle is involved in an accident, take it immediately to your Local aprilia Dealer who has the equipment and knowledge to check for accidental damage which may compromise your safety.
Your aprilia dealer is ready and able to help you with any safety problems that you might have, but of course it is necessary for you to report any malfunctions to your mechanic in order for him to help you.
Do not use your vehicle if it is damaged. A damaged vehicle may become unstable or present other problems which can increase the risk of accident, and therefore of serious injury or even death.

ONLY ORIGINALS
Do not attempt to modify the position, angle or color of your license plate. Do not cover it with even a clear plastic covering. Do not modify any of the safety equipment of your vehicle, especially such safety related items as directional indicators, rear view mirrors, lights or horns.
Any modification to your vehicle will invalidate the warranty.
Do not modify your engine in an attempt to increase the horsepower. This can result in irreparable damage to the engine, as well as degradation of the performance and handling of the vehicle which could lead to an upset, and serious injury or even death.
Have your vehicle repaired only with original parts, and use only original aprilia or aprilia approved accessories. The use of aftermarket accessories and parts can seriously compromise the safety of your vehicle as well as its performance and serviceability. Any modification which affects performance or safety voids your warranty completely.
Tampering with the emissions or noise control systems on your vehicle is against the law, and can be punished by large fines.
In some jurisdictions, it can even lead to the confiscation of your vehicle.
This vehicle was not designed to be equipped with a sidecar or to be used to tow trailers or other vehicles.
aprilia does not manufacture sidecars or trailers and therefore cannot predict the effects of such accessories on the manoeuvrability or stability of the vehicle: it can only warn that such effects may be negative and that any damage to the vehicle components caused by the use of such accessories will not be covered by the warranty.

Never race other vehicles with your vehicle.
Brake with both the front and rear brakes. The use of one brake only for sudden braking may cause the vehicle to skid or make the rider lose control of the vehicle itself.
When riding down a steep hill, use the engine as a brake by selecting the same gear, or a lower gear, than you would use to climb the hill. Use front and rear brakes sparingly.
use and maintenance Mojito 50 - 150

USA
Always ride at the appropriate speed and avoid unnecessary hard acceleration. This not only is safer, but also reduces fuel consumption and increases the life of the vehicle.
If you must ride your vehicle in rainy weather, or on loose surfaces, remember that traction is greatly reduced. Under these conditions, all handling of the vehicle must be done gradually and smoothly. Sudden acceleration, braking or turning may make you lose control of your vehicle. When traction is reduced, accelerate and slow using your vehicle»s engine braking insofar as possible. Avoid rapid, harsh application of the brakes.
Gradually open and close the throttle, to avoid spinning or skidding the rear wheel.
On rough road surfaces, slow down and ride with particular care.
Try to avoid wide open throttle accelerations, unless they are necessary for such things as passing.
Don»t allow your engine to ≈lug,∆ that is, run at too low an rpm. Shift down to a lower gear. Also, don»t over-rev the engine. Observe the redline on the tachometer.
Remember that excessively aggressive cornering can cause your vehicle»s tires to lose sideways traction, which can result in an upset and serious injury or even death.
Page 27
APRum_MOJ50_150#02_####.book Page 27 Tuesday, June 6, 2006 5:29 PM
Always observe posted and statutory speed limits, but do not assume that you can ride as fast as the speed limit under all road conditions. Slowing down a little can greatly increase your safety under all road conditions.
Do not ride your vehicle off road. Do not tamper with the muffler system or
the emissions control system of your vehicle. This is not only bad for the environment, it can subject you to serious penalties.

CLOTHING

Before riding your vehicle, ensure that your riding gear is in good condition. To be effective, your helmet must fit properly, and the visor or other eye protection must be clean.
Both research and experience have shown that drivers of other vehicles often do not see vehicles or riders. In order to make yourself more conspicuous to these drivers, wear bright reflective clothing, such as a reflective vest, or clothing with reflective sections sewn into the jacket, pants and gloves. Be particular aware of approaching automobiles and trucks that might be trying to turn left in front of you. Many vehicle accidents are caused by an opposing automobile driver making a left turn without warning in front of the vehicle.
Inevitably, the driver will look right at you, and yet swear that they did not see you before they turned directly into your path. Ride alert!
Wear protective clothing, preferably in light and/or reflecting colors. In this way you will make yourself more visible to the other drivers, thus notably reducing the risk of being knocked down, and you will be more protected in case of fall.
Always wear your crash helmet. Many accidents are fatal because of injuries to the head.
This clothing should be very tight-fitting and fastened 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.

Do not carry sharp objects in your pockets that could be dangerous in case of an upset, for example, pens or mechanical pencils, etc. Also, make sure that your passengers follow this recommendation.

ACCESSORIES

The owner of the vehicle is responsible for the choice, installation and use of any accessory.
The installation of inappropriate accessories or the overloading of the vehicle may result in the instability of the vehicle itself and cause accidents with consequent risk of serious injuries or even death. Windshields could be particularly dangerous, as they can break and injure or cut the rider in case of accident. In case of doubts with regard to any accessory you would like to install or any load you would like to carry, previously consult your Local aprilia Dealer.
use and maintenance Mojito 50 - 150
28
USA
Avoid installing accessories that cover horns or lights or that could impair their functions, limit the suspension stroke and the steering angle, hamper the operation 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.
Fairings and windshields installed on the vehicle may produce aerodynamic forces that will affect the stability of the vehicle during use, especially at high speeds.
Make sure that anything you carry on your vehicle is securely attached, and cannot come lose and jam the wheels, forks, etc. Do not install any electrical accessories, and do not modify the electrical system of your vehicle. Anything that could cause an electrical overload or other fault could cause the vehicle to suddenly stop, the lights to dim or quit, or the horn and other safety accessories not to work. Use only genuine aprilia accessories.

LOAD

Do not overload your vehicle. Attach luggage or packages as close as possible to the center of your vehicle and distribute the load from side to side as evenly as possible, to keep imbalance to a minimum. Remember that loads tend to loosen with riding, so frequently check the security of your load.

KG!
Do not hang anything from your vehicle handlebars, fenders, or forks, because this will upset the handling of your vehicle, and could prevent you from avoiding an accident. Failure to heed this warning can lead to an upset with subsequent serious injury or even death.
Do not ride with your crash helmet hung from the strap because it could easily foul the wheels, fenders, or forks, causing an upset and subsequent serious injury or even death.
Carry a passenger only if your vehicle is equipped with passenger footrests, handgrips for the passenger to hold on to, and a passenger saddle.
When carrying a passenger, remember that your vehicle»s handling is degraded, that the brakes are less efficient, and the center of gravity is higher and further to the rear.
This makes it more likely that the front wheel will come up off the ground, especially on acceleration. Therefore, you should avoid hard acceleration and hard braking. Many accidents are caused by inexperienced riders carrying passengers. Remember that allowance must be made for the extra weight of the passenger for all driving maneuvers.
Avoid abrupt and excessive acceleration. Always slow down in time and calculate longer stopping and manoeuvring distances. Non-compliance with these instructions may lead to the overturning of the vehicle or to other accidents with consequent serious injuries or even death.
Never carry loosely packaged items, make sure that everything that you carry on your vehicle is carefully secured.
Do not carry packages which protrude from the luggage rack or which cover any of the signal lights, the headlight, or the horn.
Never carry animals or children on the glove compartment or on the luggage rack.
Never exceed the labeled maximum load for each saddlebag.
Overloading your vehicle seriously reduces its stability and maneuverability and can lead to an upset with subsequent serious injury or death.

MAIN COMPONENTS

FUEL

WARNING
The fuel used for internal combustion engines is extremely inflammable and in particular conditions it can become explosive. It is important to carry out the refuelling and the maintenance operations in a well-ventilated area, with the engine off. Do not smoke while refuelling or near fuel vapors, in any case avoid any contact with naked flames, sparks and any other heat source to prevent the fuel from catching fire or from exploding. Further, prevent fuel from flowing out of the fuel filler, as it could catch fire when getting in contact with the red-hot surfaces of the engine. In case some fuel has accidentally been spilt, make sure that the area is completely dry before starting the vehicle. Since petrol expands under the heat of the sun and due to the effects of sun radiation, never fill the tank to the brim. Screw the plug carefully after refilling. Avoid any contact of the fuel with the skin and the inhalation of vapors; do not swallow fuel or pour it from a receptacle into another by means of a tube.
MC50 M50
ALWAYS DISPOSE OF FUEL IN COMPLIANCE WITH ENVIRONMENTAL REGULATIONS.
KEEP OUT OF REACH OF CHILDREN.
Use only unleaded gasoline with a minimum octane rating of 91 (RON) or 81 (MON).

FRONT DISC BRAKE

WARNING
The brakes are the parts that most ensure your safety and for this reason they must always be perfectly working; check them before every trip.
A dirty disc soils the pads, with consequent reduction of the braking efficiency. Dirty pads must be replaced, while dirty discs must be cleaned with a high-quality degreaser.
The brake fluid must be changed every two years at an aprilia Official Dealer.
For any doubt regarding the perfect functioning of the braking system and in case you are not able to carry out the usual checking operations, contact your aprilia Official Dealer.
This vehicle is provided with front hydraulic disc brake.
When the disc pads wear out, the level of the fluid decreases to automatically compensate for their wear.
The brake fluid reservoir (1) is positioned near the front brake lever coupling. Periodically check the brake fluid level in the reservoir (1) and the pad wear, see page 72 (CHECKING THE BRAKE PAD WEAR).
MC50 MC150
WARNING
Do not use the vehicle if the braking system leaks fluid.
CHECKING
To check the brake fluid level, proceed as follows:
NOTE Position the vehicle on firm and
flat ground.
u Position the vehicle on the centre stand. u Rotate the handlebar, so that the fluid
contained in the brake reservoir is parallel to the ≈MIN∆ mark stamped on the glass gauge (2).
u Make sure that the fluid contained in the
reservoir exceeds the ≈MIN∆ mark stamped on the glass gauge (2).
MIN = minimum level. If the fluid does not reach at least the MIN
mark:
MC50 MC150
CAUTION
When the disc pads wear out, the level of the fluid decreases progressively to compensate for their wear.
u Check the brake pad wear, see see
page 72 (CHECKING THE BRAKE PAD
WEAR). If the pads and / or the disc do not need replacing:
u Contact an aprilia Official Dealer, who
will provide for topping up.
CAUTION
Check the braking efficiency. In case of excessive stroke of the brake
lever or reduced efficiency of the braking system, contact an aprilia Official Dealer, since it may be necessary to bleed the system.

TYRES

This vehicle is provided with tubeless tires.
WARNING
Periodically check the tire inflation pressure at room temperature, see page 104 (TECHNICAL DATA).
If the tires are hot, the measurement is not correct. Carry out the measurement especially before and after long rides.
If the inflation pressure is too high, the ground unevenness cannot be
If, on the contrary, the inflation pressure is too low, the tire sides (1) are under greater stress and the tire itself may slip on the rim or it may become loose, with consequent loss of control of the vehicle. In case of sudden braking the tires could even get out of the rims. Further, the vehicle could skid while turning.
Check the surface and the wear of the tires, since tires in bad conditions can impair both the grip and the controllability of the vehicle.
dampened and is therefore transmitted to the handlebar, thus compromising the driving comfort and reducing road holding turns.
Some types of tires homologated for this vehicle are provided with wear indicators. There are several kinds of wear indicators. For more information on how to check the wear, contact your Dealer. Visually check if the tires are worn and

CATALYTIC SILENCER

Avoid parking the vehicle catalytic version near dry brush wood or in places easily accessible to children, as the catalytic silencer becomes extremely hot during use; be very careful and avoid any kind of contact before it has completely cooled down.
The catalytic vehicle 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.

Page 52
APRum_MOJ50_150#02_####.book Page 52 Tuesday, June 6, 2006 5:29 PM
Due to 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 exhaust fumes.
To have the catalytic converter function correctly and for long time and to reduce possible problems regarding the soiling 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, just make sure that the temperature of the thermal unit has reached at least 122 °F (50 °C); which generally occurs a few seconds after starting the engine.
CAUTION
Do not use leaded petrol, since it causes the destruction of the catalytic converter.
the use of the vehicle after such device
or element of design has been removed
or rendered inoperative by any person. Check the exhaust silencer and the silencer pipes, making sure that there are neither signs of rust nor holes, and that the exhaust system works effectively.
If the noise produced by the exhaust system increases, immediately contact your aprilia Official Dealer.

EXHAUST SILENCER

WARNING
Tampering with the noise control system is prohibited.
Owners are warned that the law may prohibit:

DEPARTURE AND DRIVE

NOTE Before departure, read the ≈Safe
Drive guide on page 5 (SAFE DRIVE).
CAUTION
If, while driving the vehicle, the dashboard low fuel warning light “ ” lights up, this means that the fuel is in the reserve area. Refuel the vehicle as soon as possible, see page 45 (FUEL).
WARNING
M50 MC50
Mentions of driving with pillion passenger are only applicable to countries where this allowed by local legislation.
MC150
WARNING
When riding without a pillion passenger, make sure the passenger footrests are folded.
When riding the vehicle, keep your hands on the handlebars and feet on the footrests.
NEVER RIDE IN ANY POSITION OTHER THAN THOSE INDICATED.
If riding with a pillion passenger, make sure the passenger knows how to behave so as not to create handling difficulties.
Before departure, make sure the stand or stands are completely up.
To leave:
u Release the throttle grip (Pos. A),
operate the rear brake and move the vehicle off its stand.
u Sit on the saddle and keep at least one
foot on the ground to stabilize the vehicle.

WARNING
Before entering a curve, reduce your speed and brake, then ride through the curve at constant speed or slightly accelerating; do not brake fully: this will very likely lead to skidding.
Using the brakes continuously on downhills can overheat the brake pads and reduce braking performance. Exploit engine compression by using both brakes intermittently. Do not ride downhill with the engine off.
CAUTION
Do not move off quickly when the engine is cold. To reduce polluting emissions and fuel consumption, warm up the engine by riding at a moderate speed for the first few kilometers.
u Do not accelerate and decelerate
repeatedly as this can lead to losing control of the vehicle.
use and maintenance Mojito 50 - 150
58
USA
WARNING
When braking, operate both brakes for even deceleration, with a gradual pressure on the brake levers. Using only the front or rear brake reduces braking performance, and may lock up a wheel and lose road holding.
If stopping on an uphill, decelerate completely and use the brake to hold the vehicle stationary. Using the engine to hold the vehicle steady can overheat the speed variator.
WARNING
On a wet or slippery surface (snow, ice, mud, etc.), ride at a low speed, without sudden braking or turns which could cause the vehicle to skid and fall over.
Pay attention to obstacles or variations in the road surface. Loose surfaces, tracks, manhole covers, painted road signals, metal plates used on construction sites, all become slippery in the rain, and should be approached with caution, driving evenly and with the vehicle as upright as possible.
Page 59
APRum_MOJ50_150#02_####.book Page 59 Tuesday, June 6, 2006 5:29 PM
WARNING
Always indicate lane changes or turns with the provided equipment and in advance, and avoid sudden, potentially dangerous manoeuvres. Switch off indicators immediately after turning.
Take care when overtaking or being overtaken. In the rain, the mist produced by large vehicles reduces visibility; the turbulence produced by large vehicles can cause loss of control of the vehicle.

CHECKING THE BRAKE PAD WEAR

Carefully read page 47 (BRAKE FLUID – recommendations), page 48 (FRONT DISC BRAKE) and page 63 (MAINTENANCE).
M50 MC50
Check the wear of the brake
pads after the first 312 mi (500 Km) and every 1250 mi (2000 Km) thereafter.
MC150
Check the wear of the brake pads after the first 625 mi (1000 Km) and every 1250 mi (2000 Km) thereafter.
Disc brake pad wear depends on use, driving style and type of road. Wear is greatest when the vehicle is ridden on dirty or wet roads.

USA
WARNING
Check the brake pads for wear before every trip.
To run a quick brake pad wear check, proceed as follows:
u Place the vehicle on its centre stand. u Remove the brake caliper cover (1). u Visually check the brake disc and pads.
WARNING
The excessive wear of the friction material would cause the contact of the pad metal support with the disc, with consequent metallic noise and production of sparks from the caliper; braking efficiency, safety and soundness of the disc would thus be negatively affected.
u If the braking surface thickness (even of
a single pad) is down to around 0.06 in (1.5 mm) ( or if even one of the wear
MC150
indicators is no longer visible), replace both pads.
