SAFETY INFORMATION

Be a Responsible Owner
1
As the vehicle’s owner, you are respon­sible for the safe and proper operation of your scooter. Scooters are single-track vehicles. Their safe use and operation are de­pendent upon the use of proper riding techniques as well as the expertise of the operator. Every operator should know the following requirements before riding this scooter. He or she should:
● Obtain thorough instructions from
a competent source on all aspects of scooter operation.
● Observe the warnings and mainte-
nance requirements in this Own­er’s Manual.
● Obtain qualified training in safe
and proper riding techniques.
● Obtain professional technical ser-
vice as indicated in this Owner’s Manual and/or when made neces­sary by mechanical conditions.
EAU10269
Safe Riding
Perform the pre-operation checks each time you use the vehicle to make sure it is in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage. See page 4-1 for a list of pre-operation checks.
● This scooter is designed to carry
the operator and a passenger.
● The failure of motorists to detect
and recognize scooters in traffic is the predominating cause of auto­mobile/scooter accidents. Many accidents have been caused by an automobile driver who did not see the scooter. Making yourself con­spicuous appears to be very effec­tive in reducing the chance of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you are approaching and passing through intersections, since in­tersections are the most likely places for scooter accidents to occur.
• Ride where other motorists can see you. Avoid riding in another motorist’s blind spot.
● Many accidents involve inexperi-
enced operators. In fact, many op­erators who have been involved in accidents do not even have a cur­rent driver’s license.
• Make sure that you are qualified and that you only lend your scooter to other qualified opera­tors.
• Know your skills and limits. Staying within your limits may help you to avoid an accident.
• We recommend that you prac­tice riding your scooter where there is no traffic until you have become thoroughly familiar with the scooter and all of its con­trols.
● Many accidents have been caused
by error of the scooter operator. A typical error made by the operator is veering wide on a turn due to ex-
1-1
SAFETY INFORMATION
cessive speed or undercornering (insufficient lean angle for the speed).
• Always obey the speed limit and never travel faster than warrant­ed by road and traffic conditions.
• Always signal before turning or changing lanes. Make sure that other motorists can see you.
● The posture of the operator and
passenger is important for proper control.
• The operator should keep both hands on the handlebar and both feet on the operator foot­rests during operation to main­tain control of the scooter.
• The passenger should always hold onto the operator, the seat strap or grab bar, if equipped, with both hands and keep both feet on the passenger footrests. Never carry a passenger unless he or she can firmly place both feet on the passenger footrests.
● Never ride under the influence of
alcohol or other drugs.
● This scooter is designed for on-
road use only. It is not suitable for off-road use.
Protective Apparel
The majority of fatalities from scooter accidents are the result of head inju­ries. The use of a safety helmet is the single most critical factor in the preven­tion or reduction of head injuries.
● Always wear an approved helmet.
● Wear a face shield or goggles.
Wind in your unprotected eyes could contribute to an impairment of vision that could delay seeing a hazard.
● The use of a jacket, substantial
shoes, trousers, gloves, etc., is ef­fective in preventing or reducing abrasions or lacerations.
● Never wear loose-fitting clothes,
otherwise they could catch on the control levers or wheels and cause injury or an accident.
● Always wear protective clothing
that covers your legs, ankles, and feet. The engine or exhaust sys­tem become very hot during or af­ter operation and can cause burns.
1-2
● A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing car­bon monoxide can cause headaches, dizziness, drowsiness, nausea, confu­sion, and eventually death. Carbon Monoxide is a colorless, odor­less, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in enclosed or poorly ventilated areas. If you experience any symptoms of carbon monoxide poison­ing, leave the area immediately, get fresh air, and SEEK MEDICAL TREAT­MENT.
● Do not run engine indoors. Even if
you try to ventilate engine exhaust with fans or open windows and doors, carbon monoxide can rap­idly reach dangerous levels.
1
SAFETY INFORMATION
● Do not run engine in poorly venti-
lated or partially enclosed areas such as barns, garages, or car-
1
ports.
● Do not run engine outdoors where
engine exhaust can be drawn into a building through openings such as windows and doors.
Loading
Adding accessories or cargo to your scooter can adversely affect stability and handling if the weight distribution of the scooter is changed. To avoid the possibility of an accident, use extreme caution when adding cargo or accesso­ries to your scooter. Use extra care when riding a scooter that has added cargo or accessories. Here, along with the information about accessories be­low, are some general guidelines to fol­low if loading cargo to your scooter: The total weight of the operator, pas­senger, accessories and cargo must not exceed the maximum load limit.
Operation of an overloaded vehicle could cause an accident.
Maximum load:
165 kg (364 lb)
When loading within this weight limit, keep the following in mind:
● Cargo and accessory weight
should be kept as low and close to the scooter as possible. Securely pack your heaviest items as close to the center of the vehicle as pos­sible and make sure to distribute the weight as evenly as possible on both sides of the scooter to min­imize imbalance or instability.
● Shifting weights can create a sud-
den imbalance. Make sure that ac­cessories and cargo are securely attached to the scooter before riding. Check accessory mounts and cargo restraints frequently.
• Properly adjust the suspension for your load (suspension-ad­justable models only), and check the condition and pres­sure of your tires.
• Never attach any large or heavy items to the handlebar, front fork, or front fender. Such items can create unstable handling or a slow steering response.
● This vehicle is not designed to
pull a trailer or to be attached to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle is an important decision. Genuine Yamaha accessories, which are avail­able only from a Yamaha dealer, have been designed, tested, and approved by Yamaha for use on your vehicle. Many companies with no connection to Yamaha manufacture parts and acces­sories or offer other modifications for Yamaha vehicles. Yamaha is not in a position to test the products that these aftermarket companies produce. Therefore, Yamaha can neither en­dorse nor recommend the use of ac­cessories not sold by Yamaha or modifications not specifically recom­mended by Yamaha, even if sold and installed by a Yamaha dealer.
1-3
SAFETY INFORMATION
Aftermarket Parts, Accessories, and Modifications
While you may find aftermarket prod­ucts similar in design and quality to genuine Yamaha accessories, recog­nize that some aftermarket accessories or modifications are not suitable be­cause of potential safety hazards to you or others. Installing aftermarket prod­ucts or having other modifications per­formed to your vehicle that change any of the vehicle’s design or operation characteristics can put you and others at greater risk of serious injury or death. You are responsible for injuries related to changes in the vehicle. Keep the following guidelines in mind, as well as those provided under “Load­ing” when mounting accessories.
● Never install accessories or carry
cargo that would impair the perfor­mance of your scooter. Carefully inspect the accessory before using it to make sure that it does not in any way reduce ground clearance or cornering clearance, limit sus-
pension travel, steering travel or control operation, or obscure lights or reflectors.
• Accessories fitted to the handle­bar or the front fork area can create instability due to improper weight distribution or aerody­namic changes. If accessories are added to the handlebar or front fork area, they must be as lightweight as possible and should be kept to a minimum.
• Bulky or large accessories may seriously affect the stability of the scooter due to aerodynamic effects. Wind may attempt to lift the scooter, or the scooter may become unstable in cross winds. These accessories may also cause instability when passing or being passed by large vehicles.
• Certain accessories can dis­place the operator from his or her normal riding position. This improper position limits the free­dom of movement of the opera-
tor and may limit control ability, therefore, such accessories are not recommended.
● Use caution when adding electri-
cal accessories. If electrical acces­sories exceed the capacity of the scooter’s electrical system, an electric failure could result, which could cause a dangerous loss of lights or engine power.
Aftermarket Tires and Rims
The tires and rims that came with your scooter were designed to match the performance capabilities and to provide the best combination of handling, brak­ing, and comfort. Other tires, rims, siz­es, and combinations may not be appropriate. Refer to page 6-16 for tire specifications and more information on replacing your tires.
Transporting the Scooter
Be sure to observe following instruc­tions before transporting the scooter in another vehicle.
● Remove all loose items from the
scooter.
1
1-4
SAFETY INFORMATION
● Point the front wheel straight
ahead on the trailer or in the truck bed, and choke it in a rail to pre-
1
vent movement.
● Secure the scooter with tie-downs
or suitable straps that are attached to solid parts of the scooter, such as the frame or upper front fork tri­ple clamp (and not, for example, to rubber-mounted handlebars or turn signals, or parts that could break). Choose the location for the straps carefully so the straps will not rub against painted surfaces during transport.
● The suspension should be com-
pressed somewhat by the tie­downs, if possible, so that the scooter will not bounce excessive­ly during transport.

Further safe-riding points

● Make sure to signal clearly when
making turns.
Left turn
Right turn
EAU45371
● Braking can be extremely difficult
on a wet road. Avoid hard braking, because the scooter could slide. Apply the brakes slowly when stopping on a wet surface.
● Slow down as you approach a cor-
ner or turn. Once you have com­pleted a turn, accelerate slowly.
● Be careful when passing parked
cars. A driver might not see you and open a door in your path.
● Railroad crossings, streetcar rails,
iron plates on road construction sites, and manhole covers be­come extremely slippery when wet. Slow down and cross them with caution. Keep the scooter up­right, otherwise it could slide out from under you.
● The brake pads and linings could
get wet when you wash the scoot­er. After washing the scooter, check the brakes before riding.
● Always wear a helmet, gloves,
trousers (tapered around the cuff and ankle so they do not flap), and a bright colored jacket.
1-5
● Do not carry too much luggage on
the scooter. An overloaded scoot­er is unstable. Use a strong cord to secure any luggage to the carriers. A loose load will affect the stability of the scooter and could divert your attention from the road. (See page 1-3.)

Fuel

Make sure there is sufficient gasoline in the tank.
EWA10881
Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions.
1. Before refueling, turn off the en­gine and be sure that no one is sit­ting on the vehicle. Never refuel while smoking, or while in the vi­cinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel tank filler hole. Stop filling when the fuel reaches the bottom of the filler tube. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank.

ately. If gasoline spills on your skin, wash with soap and water. If gaso­line spills on your clothing, change your clothes.
Recommended fuel:
Regular unleaded gasoline only
Fuel tank capacity:
5.0 L (1.32 US gal, 1.10 Imp.gal)
Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as the valves and piston rings, as well as to the exhaust system.
Your Yamaha engine has been de­signed to use regular unleaded gaso­line with a research octane number of 95 or higher. If knocking (or pinging) oc­curs, use a gasoline of a different brand or premium unleaded fuel. Use of un­leaded fuel will extend spark plug life and reduce maintenance costs.

Catalytic converters

This vehicle is equipped with catalytic converters in the exhaust system.
EWA10862
The exhaust system is hot after op­eration. To prevent a fire hazard or burns:
● Do not park the vehicle near
possible fire hazards such as grass or other materials that easily burn.
● Park the vehicle in a place
where pedestrians or children are not likely to touch the hot exhaust system.
● Make sure that the exhaust sys-
tem has cooled down before do­ing any maintenance work.
● Do not allow the engine to idle
more than a few minutes. Long idling can cause a build-up of heat.
Use only unleaded gasoline. The use of leaded gasoline will cause unre­pairable damage to the catalytic converter.

1. Sidestand
The sidestand is located on the left side of the frame. Raise the sidestand or lower it with your foot while holding the vehicle upright.
The built-in sidestand switch is part of the ignition circuit cut-off system, which cuts the ignition in certain situations. (See the following section for an expla­nation of the ignition circuit cut-off sys­tem.)
EWA10241
The vehicle must not be ridden with the sidestand down, or if the side­stand cannot be properly moved up (or does not stay up), otherwise the sidestand could contact the ground and distract the operator, resulting in a possible loss of control. Yamaha’s ignition circuit cut-off system has been designed to assist the operator in fulfilling the respon­sibility of raising the sidestand be­fore starting off. Therefore, check this system regularly and have a Yamaha dealer repair it if it does not function properly.

Ignition circuit cut-off system

The ignition circuit cut-off system (com­prising the sidestand switch and brake light switches) has the following func­tions.
● It prevents starting when the side-
stand is up, but neither brake is ap­plied.
● It prevents starting when either
brake is applied, but the sidestand is still down.
● It cuts the running engine when the
sidestand is moved down. Periodically check the operation of the ignition circuit cut-off system according to the following procedure.
This check is most reliable if performed with a warmed-up engine.

Braking

EWA10300
● Avoid braking hard or suddenly
(especially when leaning over to one side), otherwise the scooter may skid or overturn.
● Railroad crossings, streetcar
rails, iron plates on road con­struction sites, and manhole covers become extremely slip­pery when wet. Therefore, slow down when approaching such areas and cross them with cau­tion.
● Keep in mind that braking on a
wet road is much more difficult.
● Ride slowly down a hill, as brak-
ing downhill can be very diffi­cult.
1. Close the throttle completely.
2. Apply both front and rear brakes simultaneously while gradually in­creasing the pressure.

OPERATION AND IMPORTANT RIDING POINTS
Tips for reducing fuel con­sumption
Fuel consumption depends largely on your riding style. Consider the following tips to reduce fuel consumption:
● Avoid high engine speeds during
acceleration.
● Avoid high engine speeds with no
load on the engine.
● Turn the engine off instead of let-
ting it idle for an extended length of
5
time (e.g., in traffic jams, at traffic lights or at railroad crossings).

Engine break-in

There is never a more important period in the life of your engine than the period between 0 and 1000 km (600 mi). For this reason, you should read the follow­ing material carefully. Since the engine is brand new, do not put an excessive load on it for the first 1000 km (600 mi). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full-throt­tle operation or any condition that might
result in engine overheating must be avoided.
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3 throttle.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2 throttle.

Checking the spark plug

The spark plug is an important engine component, which is easy to check. Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accordance with the periodic mainte­nance and lubrication chart. In addition, the condition of the spark plug can re­veal the condition of the engine.
To remove the spark plug
1. Place the vehicle on the center­stand.
2. Remove panel A. (See page 6-7.)

● Have a Yamaha dealer replace
excessively worn tires. Besides being illegal, operating the vehi­cle with excessively worn tires decreases riding stability and can lead to loss of control.
● The replacement of all wheel
and brake-related parts, includ­ing the tires, should be left to a
EWA10471
Yamaha dealer, who has the necessary professional knowl­edge and experience to do so.
● Ride at moderate speeds after
changing a tire since the tire surface must first be “broken in” for it to develop its optimal characteristics.

Cast wheels

To maximize the performance, durabil­ity, and safe operation of your vehicle, note the following points regarding the specified wheels.
● The wheel rims should be checked
for cracks, bends, warpage or oth­er damage before each ride. If any damage is found, have a Yamaha dealer replace the wheel. Do not attempt even the smallest repair to the wheel. A deformed or cracked wheel must be replaced.
● The wheel should be balanced
whenever either the tire or wheel has been changed or replaced. An unbalanced wheel can result in poor performance, adverse han­dling characteristics, and a short­ened tire life.

Checking the brake fluid level

Before riding, check that the brake fluid is above the minimum level mark. Check the brake fluid level with the top of the reservoir level. Replenish the brake fluid if necessary.
1. Minimum level mark
Specified brake fluid:
DOT 3 or DOT 4
EWA15980
Improper maintenance can result in loss of braking ability. Observe these precautions:
● Insufficient brake fluid may al-
low air to enter the brake sys­tem, reducing braking performance.
● Clean the filler cap before re-
moving. Use only DOT 3 or DOT 4 brake fluid from a sealed con­tainer.
● Use only the specified brake flu-
id; otherwise, the rubber seals may deteriorate, causing leak­age.
● Refill with the same type of
brake fluid. Adding a brake fluid other than DOT 3 or DOT 4 may result in a harmful chemical re­action.
● Be careful that water does not
enter the brake fluid reservoir when refilling. Water will signifi­cantly lower the boiling point of the fluid and may result in vapor lock.
Brake fluid may damage painted sur­faces or plastic parts. Always clean up spilled fluid immediately.
As the brake pads wear, it is normal for the brake fluid level to gradually go down. A low brake fluid level may indi­cate worn brake pads and/or brake sys­tem leakage; therefore, be sure to check the brake pads for wear and the brake system for leakage. If the brake fluid level goes down suddenly, have a Yamaha dealer check the cause before further riding.

Troubleshooting

Although Yamaha scooters receive a thorough inspection before shipment from the factory, trouble may occur dur­ing operation. Any problem in the fuel, compression, or ignition systems, for example, can cause poor starting and loss of power. The following troubleshooting chart represents a quick and easy procedure for checking these vital systems your­self. However, should your scooter re­quire any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the scooter prop­erly. Use only genuine Yamaha replace­ment parts. Imitation parts may look like Yamaha parts, but they are often inferi­or, have a shorter service life and can lead to expensive repair bills.

Care

While the open design of a scooter re­veals the attractiveness of the technol­ogy, it also makes it more vulnerable. Rust and corrosion can develop even if high-quality components are used. A rusty exhaust pipe may go unnoticed on a car, however, it detracts from the overall appearance of a scooter. Fre­quent and proper care does not only comply with the terms of the warranty, but it will also keep your scooter looking good, extend its life and optimize its performance.
Before cleaning
1. Cover the muffler outlet with a plastic bag after the engine has cooled down.
2. Make sure that all caps and covers as well as all electrical couplers and connectors, including the spark plug cap, are tightly in­stalled.
3. Remove extremely stubborn dirt, like oil burnt onto the crankcase, with a degreasing agent and a brush, but never apply such prod-
ucts onto seals, gaskets and wheel axles. Always rinse the dirt and de­greaser off with water.
Cleaning
● Avoid using strong acidic wheel
cleaners, especially on spoked wheels. If such products are used on hard-to-remove dirt, do not leave the cleaner on the af­fected area any longer than in­structed. Also, thoroughly rinse the area off with water, immedi­ately dry it, and then apply a cor­rosion protection spray.
● Improper cleaning can damage
plastic parts (such as cowlings, panels, windshields, headlight lenses, meter lenses, etc.) and the mufflers. Use only a soft, clean cloth or sponge with wa­ter to clean plastic. However, if the plastic parts cannot be thor­oughly cleaned with water, di­luted mild detergent with water may be used. Be sure to rinse
7-1
SCOOTER CARE AND STORAGE
TIP
off any detergent residue using plenty of water, as it is harmful to plastic parts.
● Do not use any harsh chemical
products on plastic parts. Be sure to avoid using cloths or sponges which have been in contact with strong or abrasive cleaning products, solvent or thinner, fuel (gasoline), rust re­movers or inhibitors, brake flu­id, antifreeze or electrolyte.
● Do not use high-pressure wash-
ers or steam-jet cleaners since they cause water seepage and deterioration in the following ar­eas: seals (of wheel and swing­arm bearings, fork and brakes), electric components (couplers, connectors, instruments, switches and lights), breather hoses and vents.
● For scooters equipped with a
windshield: Do not use strong cleaners or hard sponges as they will cause dulling or scratching. Some cleaning com­pounds for plastic may leave scratches on the windshield.
Test the product on a small hid­den part of the windshield to make sure that it does not leave any marks. If the windshield is scratched, use a quality plastic polishing compound after washing.
After normal use Remove dirt with warm water, a mild detergent, and a soft, clean sponge, and then rinse thoroughly with clean water. Use a toothbrush or bottlebrush for hard-to-reach areas. Stubborn dirt and insects will come off more easily if the area is covered with a wet cloth for a few minutes before cleaning.
After riding in the rain, near the sea or on salt-sprayed roads Since sea salt or salt sprayed on the roads during winter are extremely cor­rosive in combination with water, carry out the following steps after each ride in the rain, near the sea or on salt­sprayed roads.
7-2
Salt sprayed on roads in the winter may remain well into spring.
1. Clean the scooter with cold water and a mild detergent after the en­gine has cooled down. NOTICE:
Do not use warm water since it increases the corrosive action of the salt.
[ECA10791]
2. Apply a corrosion protection spray on all metal, including chrome- and nickel-plated, surfaces to prevent corrosion.
After cleaning
1. Dry the scooter with a chamois or an absorbing cloth.
2. Use a chrome polish to shine chrome, aluminum and stainless­steel parts, including the exhaust system. (Even the thermally in­duced discoloring of stainless­steel exhaust systems can be re­moved through polishing.)

5. Touch up minor paint damage caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely be­fore storing or covering it.
Contaminants on the brakes or tires can cause loss of control.
● Make sure that there is no oil or

● Apply spray oil and wax spar-
ingly and make sure to wipe off any excess.
● Never apply oil or wax to any
rubber and plastic parts, but treat them with a suitable care product.
● Avoid using abrasive polishing
compounds as they will wear away the paint.
● Consult a Yamaha dealer for ad-
vice on what products to use.
● Washing, rainy weather or humid
climates can cause the headlight lens to fog. Turning the headlight on for a short period of time will help remove the moisture from the lens.

Storage

Short-term
Always store your scooter in a cool, dry place and, if necessary, protect it against dust with a porous cover. Be sure the engine and the exhaust sys­tem are cool before covering the scoot­er.
● Storing the scooter in a poorly
ventilated room or covering it with a tarp, while it is still wet, will allow water and humidity to seep in and cause rust.
● To prevent corrosion, avoid
damp cellars, stables (because of the presence of ammonia) and areas where strong chemi­cals are stored.
Long-term
Before storing your scooter for several months:
1. Follow all the instructions in the “Care” section of this chapter.

SCOOTER CARE AND STORAGE
TIP
2. Drain the carburetor float chamber by loosening the drain bolt; this will prevent fuel deposits from building up. Pour the drained fuel into the fuel tank.
3. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel tank from rusting and the fuel from deteriorating.
4. Perform the following steps to pro­tect the cylinder, piston rings, etc. from corrosion. a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place the spark plug on the cylinder head so that the electrodes are grounded. (This will limit spark­ing during the next step.)
d. Turn the engine over several
times with the starter. (This will coat the cylinder wall with oil.)
WARNING! To prevent dam­age or injury from sparking, make sure to ground the
spark plug electrodes while turning the engine over.
[EWA10951]
e. Remove the spark plug cap
from the spark plug, and then install the spark plug and the spark plug cap.
5. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the side­stand/centerstand.
6. Check and, if necessary, correct the tire air pressure, and then lift the scooter so that both of its wheels are off the ground. Alterna­tively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot.
7. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.
8. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a month. Do not store the battery in an ex­cessively cold or warm place [less than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information on storing the battery, see page 6-24.
