Be a Responsible OwnerAs the vehicle’s owner, you are res-ponsible for the safe and proper ope-ration of your scooter.Scooters are single-track vehicles.Their safe use and operation aredependent upon the use of properriding techniques as well as theexpertise of the operator. Every ope-rator should know the following requi-rements before riding this scooter.He or she should:

� Obtain thorough instructionsfrom a competent source on allaspects of scooter operation.

� Observe the warnings and main-tenance requirements in thisOwner’s Manual.

� Obtain qualified training in safeand proper riding techniques.

� Obtain professional technicalservice as indicated in thisOwner’s Manual and/or whenmade necessary by mechanicalconditions.

Safe RidingPerform the pre-operation checkseach time you use the vehicle tomake sure it is in safe operating con-dition. Failure to inspect or maintainthe vehicle properly increases thepossibility of an accident or equip-ment damage. See page 4-1 for a listof pre-operation checks.

� This scooter is designed to carrythe operator and a passenger.

TIPAlthough this scooter is designed tocarry a passenger, always complywith the local regulations.

� The failure of motorists to detectand recognize scooters in trafficis the predominating cause ofautomobile/scooter accidents.Many accidents have been cau-sed by an automobile driver whodid not see the scooter. Makingyourself conspicuous appears tobe very effective in reducing thechance of this type of accident.Therefore:• Wear a brightly colored jacket.

• Use extra caution when youare approaching and passingthrough intersections, sinceintersections are the mostlikely places for scooter acci-dents to occur.

• Ride where other motorists cansee you. Avoid riding in anot-her motorist’s blind spot.

� Many accidents involve inexpe-rienced operators. In fact, manyoperators who have been invol-ved in accidents do not evenhave a current driver’s license.• Make sure that you are quali-

fied and that you only lend yourscooter to other qualified ope-rators.

• Know your skills and limits.Staying within your limits mayhelp you to avoid an accident.

• We recommend that you prac-tice riding your scooter wherethere is no traffic until you havebecome thoroughly familiarwith the scooter and all of itscontrols.

� Many accidents have been cau-sed by error of the scooter ope-

1

SAFETY INFORMATION

1-1

5C2-F8199-E3 7/9/10 18:10 Página 8

rator. A typical error made by theoperator is veering wide on a turndue to excessive speed or under-cornering (insufficient lean anglefor the speed).• Always obey the speed limit

and never travel faster thanwarranted by road and trafficconditions.

• Always signal before turning orchanging lanes. Make sure thatother motorists can see you.

� The posture of the operator andpassenger is important for propercontrol.• The operator should keep both

hands on the handlebar andboth feet on the operator foo-trests during operation tomaintain control of the scooter.

• The passenger should alwayshold onto the operator, the seatstrap or grab bar, if equipped,with both hands and keep bothfeet on the passenger foo-trests. Never carry a passengerunless he or she can firmly pla-ce both feet on the passengerfootrests.

� Never ride under the influence ofalcohol or other drugs.

� This scooter is designed for on-road use only. It is not suitable foroff-road use.

Protective apparelThe majority of fatalities from scooteraccidents are the result of head inju-ries. The use of a safety helmet is thesingle most critical factor in the pre-vention or reduction of head injuries.

� Always wear an approved hel-met.

� Wear a face shield or goggles.Wind in your unprotected eyescould contribute to an impair-ment of vision that could delayseeing a hazard.

� The use of a jacket, substantialshoes, trousers, gloves, etc., iseffective in preventing or redu-cing abrasions or lacerations.

� Never wear loose-fitting clothes,otherwise they could catch onthe control levers or wheels andcause injury or an accident.

� Always wear protective clothingthat covers your legs, ankles, and

feet. The engine or exhaust sys-tem become very hot during orafter operation and can causeburns.

� A passenger should also observethe above precautions.

Avoid Carbon Monoxide PoisoningAll engine exhaust contains carbonmonoxide, a deadly gas. Breathingcarbon monoxide can cause heada-ches, dizziness, drowsiness, nausea,confusion, and eventually death.Carbon Monoxide is a colorless,odorless, tasteless gas which may bepresent even if you do not see orsmell any engine exhaust. Deadlylevels of carbon monoxide can collectrapidly and you can quickly be over-come and unable to save yourself.Also, deadly levels of carbon monoxi-de can linger for hours or days inenclosed or poorly ventilated areas. Ifyou experience any symptoms of car-bon monoxide poisoning, leave thearea immediately, get fresh air, andSEEK MEDICAL TREATMENT.

� Do not run engine indoors. Evenif you try to ventilate engine

5C2-F8199-E3 7/9/10 18:10 Página 9

exhaust with fans or open win-dows and doors, carbon monoxi-de can rapidly reach dangerouslevels.

� Do not run engine in poorly venti-lated or partially enclosed areassuch as barns, garages, or car-ports.

� Do not run engine outdoors whe-re engine exhaust can be drawninto a building through openingssuch as windows and doors.

LoadingAdding accessories or cargo to yourscooter can adversely affect stabilityand handling if the weight distributionof the scooter is changed. To avoidthe possibility of an accident, useextreme caution when adding cargoor accessories to your scooter. Useextra care when riding a scooter thathas added cargo or accessories.Here, along with the informationabout accessories below, are somegeneral guidelines to follow if loadingcargo to your scooter:The total weight of the operator, pas-senger, accessories and cargo must

not exceed the maximum load limit.Operation of an overloaded vehiclecould cause an accident.

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

� Cargo and accessory weightshould be kept as low and closeto the scooter as possible. Secu-rely pack your heaviest items asclose to the center of the vehicleas possible and make sure to dis-tribute the weight as evenly aspossible on both sides of thescooter to minimize imbalance orinstability.

� Shifting weights can create asudden imbalance. Make surethat accessories and cargo aresecurely attached to the scooterbefore riding. Check accessorymounts and cargo restraints fre-quently.• Properly adjust the suspension

for your load (suspension-

adjustable models only), andcheck the condition and pres-sure of your tires.

• Never attach any large orheavy items to the handlebar,front fork, or front fender. Suchitems can create unstablehandling or a slow steering res-ponse.

� This vehicle is not designed topull a trailer or to be attachedto a sidecar.

Genuine Yamaha AccessoriesChoosing accessories for your vehicleis an important decision. GenuineYamaha accessories, which are avai-lable only from a Yamaha dealer, havebeen designed, tested, and approvedby Yamaha for use on your vehicle.Many companies with no connectionto Yamaha manufacture parts andaccessories or offer other modifica-tions for Yamaha vehicles. Yamaha isnot in a position to test the productsthat these aftermarket companiesproduce. Therefore, Yamaha can neit-her endorse nor recommend the useof accessories not sold by Yamaha or

modifications not specifically recom-mended by Yamaha, even if sold andinstalled by a Yamaha dealer.

Aftermarket Parts, Accessories,and ModificationsWhile you may find aftermarket pro-ducts similar in design and quality togenuine Yamaha accessories, recog-nize that some aftermarket accesso-ries or modifications are not suitablebecause of potential safety hazards toyou or others. Installing aftermarketproducts or having other modifica-tions performed to your vehicle thatchange any of the vehicle’s design oroperation characteristics can put youand others at greater risk of seriousinjury or death. You are responsiblefor injuries related to changes in thevehicle.Keep the following guidelines in mind,as well as those provided under “Loa-ding” when mounting accessories.

� Never install accessories or carrycargo that would impair the per-formance of your scooter. Care-fully inspect the accessory befo-re using it to make sure that it

does not in any way reduceground clearance or corneringclearance, limit suspension tra-vel, steering travel or control ope-ration, or obscure lights or reflec-tors.• Accessories fitted to the hand-

lebar or the front fork area cancreate instability due to impro-per weight distribution oraerodynamic changes. Ifaccessories are added to thehandlebar or front fork area,they must be as lightweight aspossible and should be kept toa minimum.

• Bulky or large accessories mayseriously affect the stability ofthe scooter due to aerodyna-mic effects. Wind may attemptto lift the scooter, or the scoo-ter may become unstable incross winds. These accesso-ries may also cause instabilitywhen passing or being passedby large vehicles.

• Certain accessories can dis-place the operator from his orher normal riding position.

This improper position limitsthe freedom of movement ofthe operator and may limitcontrol ability, therefore, suchaccessories are not recom-mended.

� Use caution when adding electri-cal accessories. If electricalaccessories exceed the capacityof the scooter’s electrical system,an electric failure could result,which could cause a dangerousloss of lights or engine power.

Aftermarket Tires and RimsThe tires and rims that came with yourscooter were designed to match theperformance capabilities and to pro-vide the best combination of hand-ling, braking, and comfort. Other tires,rims, sizes, and combinations maynot be appropriate. Refer to page 6-10 for tire specifications and moreinformation on replacing your tires.

Transporting the ScooterBe sure to observe following instruc-tions before transporting the scooterin another vehicle.

5C2-F8199-E3 7/9/10 18:10 Página 11

� Remove all loose items from thescooter.

� Point the front wheel straightahead on the trailer or in the truckbed, and choke it in a rail to pre-vent movement.

� Secure the scooter with tie-downs or suitable straps that areattached to solid parts of thescooter, such as the frame orupper front fork triple clamp (andnot, for example, to rubber-mounted handlebars or turn sig-nals, or parts that could break).Choose the location for thestraps carefully so the straps willnot rub against painted surfacesduring transport.

� The suspension should be com-pressed somewhat by the tie-downs, if possible, so that thescooter will not bounce excessi-vely during transport.

EAU10372

Further safe-riding points� Be sure to signal clearly when

making turns.� Braking can be extremely difficult

on a wet road. Avoid hard bra-king, because the scooter couldslide. Apply the brakes slowlywhen stopping on a wet surface.

� Slow down as you approach acorner or turn. Once you havecompleted a turn, accelerateslowly.

� Be careful when passing parkedcars. A driver might not see youand open a door in your path.

� Railroad crossings, streetcarrails, iron plates on road cons-truction sites, and manholecovers become extremely slip-pery when wet. Slow down andcross them with caution. Keepthe scooter upright, otherwise itcould slide out from under you.

� The brake pads could get wetwhen you wash the scooter. Afterwashing the scooter, check thebrakes before riding.

� Always wear a helmet, gloves,trousers (tapered around the cuffand ankle so they do not flap),and a bright colored jacket.

� Do not carry too much luggageon the scooter. An overloadedscooter is unstable. Use a strongcord to secure any luggage to thecarrier (if equipped). A loose loadwill affect the stability of the sco-oter and could divert your atten-tion from the road. (See page 1-1).

CareWhile the open design of a scooterreveals the attractiveness of the tech-nology, it also makes it more vulnera-ble. Rust and corrosion can developeven if high-quality components areused. A rusty exhaust pipe may gounnoticed on a car, however, itdetracts from the overall appearanceof a scooter. Frequent and propercare does not only comply with theterms of the warranty, but it will alsokeep your scooter looking good,extend its life and optimize its perfor-mance.

Before cleaning1. Cover the muffler outlet with a

plastic bag after the engine hascooled down.

2. Make sure that all caps andcovers as well as all electricalcouplers and connectors, inclu-ding the spark plug cap, aretightly installed.

3. Remove extremely stubborn dirt,like oil burnt onto the crankcase,with a degreasing agent and a

brush, but never apply such pro-ducts onto seals, gaskets andwheel axles. Always rinse the dirtand degreaser off with water.

CleaningECA10783

� Avoid using strong acidic whe-el cleaners, especially on spo-ked wheels. If such productsare used on hard-to-removedirt, do not leave the cleaner onthe affected area any longerthan instructed. Also, tho-roughly rinse the area off withwater, immediately dry it, andthen apply a corrosion protec-tion spray.

� Improper cleaning can damageplastic parts (such as cowlings,panels, windshields, headlightlenses, meter lenses, etc.) andthe mufflers. Use only a soft,clean cloth or sponge withwater to clean plastic. Howe-ver, if the plastic parts cannotbe thoroughly cleaned withwater, diluted mild detergent

� Do not use any harsh chemicalproducts on plastic parts. Besure to avoid using cloths orsponges which have been incontact with strong or abrasivecleaning products, solvent orthinner, fuel (gasoline), rustremovers or inhibitors, brakefluid, antifreeze or electrolyte.

� Do not use high-pressure was-hers or steam-jet cleaners sin-ce they cause water seepageand deterioration in the follo-wing areas: seals (of wheel andswingarm bearings, fork andbrakes), electric components(couplers, connectors, instru-ments, switches and lights),breather hoses and vents.

� For scooters equipped with awindshield: Do not use strongcleaners or hard sponges asthey will cause dulling or scrat-ching. Some cleaning com-pounds for plastic may leave

scratches on the windshield.Test the product on a small hid-den part of the windshield tomake sure that it does not lea-ve any marks. If the windshieldis scratched, use a qualityplastic polishing compoundafter washing.

After normal useRemove dirt with warm water, a milddetergent, and a soft, clean sponge,and then rinse thoroughly with cleanwater. Use a toothbrush or bottle-brush for hard-to-reach areas. Stub-born dirt and insects will come offmore easily if the area is covered witha wet cloth for a few minutes beforecleaning.

After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on theroads during winter are extremelycorrosive in combination with water,carry out the following steps aftereach ride in the rain, near the sea oron salt-sprayed roads.

TIPSalt sprayed on roads in the wintermay remain well into spring.

1. Clean the scooter with cold waterand a mild detergent after theengine has cooled down. NOTI-CE: Do not use warm watersince it increases the corrosiveaction of the salt. [ECA10791]

2. Apply a corrosion protectionspray on all metal, includingchrome- and nickel-plated, surfa-ces to prevent corrosion.

After cleaning1. Dry the scooter with a chamois or

an absorbing cloth.2. Use a chrome polish to shine

chrome, aluminum and stainless-steel parts, including the exhaustsystem. (Even the thermally indu-ced discoloring of stainless-steelexhaust systems can be removedthrough polishing.)

� Make sure that there is no oil orwax on the brakes or tires. Ifnecessary, clean the brakediscs and brake linings with aregular brake disc cleaner oracetone, and wash the tireswith warm water and a milddetergent.

� Before operating the scootertest its braking performanceand cornering behavior.

ECA10800

� Apply spray oil and wax spa-ringly and make sure to wipeoff any excess.

� Never apply oil or wax to anyrubber and plastic parts, buttreat them with a suitable careproduct.

� Avoid using abrasive polishingcompounds as they will wearaway the paint.

TIP� Consult a Yamaha dealer for

advice on what products to use.� Washing, rainy weather or humid

climates can cause the headlightlens to fog. Turning the headlighton for a short period of time willhelp remove the moisture fromthe lens.
