SAFETY INFORMATION

TIP

Be a Responsible Owner

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.

EAUT1019

 Never operate a scooter without

proper training or instruction. Take a training course. Beginners should receive training from a certified instructor. Contact an authorized scooter dealer to find out about the training courses nearest you.

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.

Although this scooter is designed to carry a passenger, always comply with the local regulations.

 The failure of motorists to detect

and recognize scooters in traffic is the predominating cause of automobile/scooter accidents. Many

1-1

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.

• Never maintain a scooter without proper knowledge. Contact an authorized scooter dealer to inform you on basic scooter maintenance. Certain maintenance can only be carried out by certified staff.

Page 9

SAFETY INFORMATION

 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 excessive 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.

1-2

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.

 A passenger should also observe

the above precautions.

Page 10

SAFETY INFORMATION

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.

 Do not run engine in poorly venti-

lated or partially enclosed areas such as barns, garages, or carports.

 Do not run engine outdoors where

engine exhaust can be drawn into a building through openings such as windows and doors.

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:

163 kg (359 lb)

When loading within this weight limit, keep the following in mind:

1-3

 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.

SAFETY INFORMATION

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.

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 suspension 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.

1-4

• 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 operator 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.

Page 12

SAFETY INFORMATION

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 6-14 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.

 Point the front wheel straight

ahead on the trailer or in the truck bed, and choke it in a rail to prevent 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 lo-

cation 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.

1-5

EAU57600

Further safe-riding points

 Be sure to signal clearly when

making turns.

 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

corner 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 or linings could

get wet when you wash the scooter. After washing the scooter, check the brakes before riding.

Page 13

 Always wear a helmet, gloves,

trousers (tapered around the cuff and ankle so they do not flap), and a brightly colored jacket.

 Do not carry too much luggage on

the scooter. An overloaded scooter is unstable. Use a strong cord to secure any luggage to the carrier (if equipped). A loose load will affect the stability of the scooter and could divert your attention from the road. (See page 1-3.)

4. Be sure to securely close the fuel tank cap.

EWA15152

Gasoline is poisonous and can cause injury or death. Handle gaso- line with care. Never siphon gasoline by mouth. If you should swallow some gasoline or inhale a lot of gas- oline vapor, or get some gasoline in your eyes, see your doctor immedi-

ately. If gasoline spills on your skin, wash with soap and water. If gaso- line spills on your clothing, change your clothes.

EAU54601

Recommended fuel:

Premium unleaded gasoline (Gasohol (E10) acceptable)

Fuel tank capacity:

5.4 L (1.43 US gal, 1.19 Imp.gal)

Fuel reserve amount (when the fuel level warning light comes on):

0.9 L (0.24 US gal, 0.20 Imp.gal)

ECA11401

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 premium unleaded gasoline with a research octane number of 95 or higher. If knocking (or pinging) occurs, use a gasoline of a different

3-9

brand. Use of unleaded fuel will extend spark plug life and reduce maintenance costs.

Gasohol

There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if the ethanol content does not exceed 10% (E10). Gasohol containing methanol is not recommended by Yamaha because it can cause damage to the fuel system or vehicle performance problems.

Braking

 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 slip-

pery 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.

PERIODIC MAINTENANCE AND ADJUSTMENT

WARNING

Periodic inspection, adjustment, and lubrication will keep your vehicle in the safest and most efficient condition possible. Safety is an obligation of the vehicle owner/operator. The most important points of vehicle inspection, adjustment, and lubrication are explained on the following pages. The intervals given in the periodic maintenance charts should be simply considered as a general guide under normal riding conditions. However, depending on the weather, terrain, geographical location, and individual use,

the maintenance intervals may need to be shortened.

Failure to properly maintain the vehicle or performing maintenance activities incorrectly may increase your risk of injury or death during service or while using the vehicle. If you are not familiar with vehicle service, have a Yamaha dealer perform service.

EAU17245

EWA10322

EWA15123

Turn off the engine when performing maintenance unless otherwise specified.

 A running engine has moving

parts that can catch on body parts or clothing and electrical parts that can cause shocks or fires.

 Running the engine while ser-

vicing can lead to eye injury, burns, fire, or carbon monoxide poisoning – possibly leading to death. See page 1-3 for more information about carbon monoxide.

EWA15461

Brake discs, calipers, drums, and linings can become very hot during use. To avoid possible burns, let brake components cool before touching them.

EAU17303

Emission controls not only function to ensure cleaner air, but are also vital to proper engine operation and maximum performance. In the following periodic maintenance charts, the services related to emissions control are grouped separately. These services require specialized data, knowledge, and equipment. Maintenance, replacement, or repair of the emission control devices and systems may be performed by any repair establishment or individual that is certified (if applicable). Yamaha dealers are trained and equipped to perform these particular services.

 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, includ- ing the tires, should be left to a

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.

Matte color caution

ECA15193

Some models are equipped with matte colored finished parts. Be sure to consult a Yamaha dealer for advice on what products to use before cleaning the vehicle. Using a brush, harsh chemical products or cleaning compounds when cleaning these parts will scratch or damage their surface. Wax also should not be applied to any matte colored finished parts.

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

ECA10784

 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, immedi- ately dry it, and then apply a cor- rosion 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, di- luted mild detergent with water may be used. Be sure to rinse

7-1

Page 68

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 re- movers 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 swing-

arm 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 scratching. Some cleaning compounds for plastic may leave scratches on the wind-

shield. Test the product on a small hidden part of the wind- shield to make sure that it does not leave any marks. If the wind- shield 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.

2. Apply a corrosion protection spray on all metal, including chromeand nickel-plated, surfaces to prevent corrosion.

Cleaning the windshield Avoid using any alkaline or strong acid cleaner, gasoline, brake fluid, or any other solvent. Clean the windshield with a cloth or sponge dampened with a mild detergent, and then wash it off thoroughly with water. For additional cleaning, use Yamaha Windshield Cleaner or another high-quality windshield cleaner. Some cleaning compounds for plastics may leave scratches on the windshield. Before using such cleaners, test an area of the

4. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the sidestand/centerstand.

5. 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.

6. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.

7. 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 6-23.

Make any necessary repairs before storing the scooter.
