QSAFETY INFORMATION

EAU10260

SCOOTERS ARE SINGLE TRACK VE-

HICLES. THEIR SAFE USE AND OP-

ERATION ARE DEPENDENT UPON

THE USE OF PROPER RIDING TECH-

NIQUES AS WELL AS THE EXPER-

TISE OF THE OPERATOR.EVERY OP-

ERATOR SHOULD KNOW THE FOL-

LOWING REQUIREMENTS BEFORE

RIDING THIS SCOOTER.

HE OR SHE SHOULD:

8OBTAIN THOROUGH INSTRUC-

TIONS FROM A COMPETENT

SOURCE ON ALL ASPECTS OF

SCOOTER OPERATION.

8OBSERVE THE WARNINGS AND

MAINTENANCE REQUIRE-

MENTS IN THE OWNER’S

MANUAL.

8OBTAIN QUALIFIED TRAINING IN

SAFE AND PROPER RIDING

TECHNIQUES.

8OBTAIN PROFESSIONAL TECH-

NICAL SERVICE AS INDICATED

BY THE OWNER’S MANUAL AND/

OR WHEN MADE NECESSARY

BY MECHANICAL CONDITIONS.

Safe riding

8Always make pre-operation checks.

Careful checks may help prevent

an accident.

8This scooter is designed to carry

the operator and passenger.

8The failure of motorists to detect

and recognize scooters in traffic is

the predominating cause of auto-

mobile/scooter accidents. Many

accidents have been caused by an

automobile driver who did not see

the scooter. Making yourself con-

spicuous appears to be very effec-

tive in reducing the chance of this

type of accident.

Therefore:

9Wear a brightly colored jacket.

9Use extra caution when

approaching and passing

through intersections, since

intersections are the most

likely places for scooter

accidents to occur.

9Ride where other motorists can

see you. Avoid riding in another

motorist’s blind spot.

8Many accidents involve inexperi-

enced operators. In fact, many op-

erators who have been involved in

accidents do not even have a cur-

rent driver’s license.

9Make sure that you are quali-

fied and that you only lend your

scooter to other qualified

operators.

9Know your skills and limits.

Staying within your limits may

help you to avoid an accident.

9We 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).

9Always obey the speed limit

and never travel faster than

warranted by road and traffic

conditions.

QSAFETY INFORMATION

9Always signal before turning or

changing lanes. Make sure that

other motorists can see you.

8The posture of the operator and

passenger is important for proper

control.

9The operator should keep both

hands on the handlebar and

both feet on the footboard

during operation to maintain

control of the scooter.

9The 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 foot-

rests.

9Never carry a passenger unless

he or she can firmly place both

feet on the passenger foot-

rests.

8Never 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.

8Always wear an approved helmet.

8Wear a face shield or goggles.Wind

in your unprotected eyes could con-

tribute to an impairment of vision

which could delay seeing a hazard.

8The use of a jacket, substantial

shoes, trousers, gloves, etc., is

effective in preventing or reducing

abrasions or lacerations.

8Never wear loose-fitting clothes,

otherwise they could catch on the

control levers or wheels and cause

injury or an accident.

8Never touch the engine or exhaust

system during or after operation.

They become very hot and can

cause burns. Always wear protec-

tive clothing that covers your legs,

ankles, and feet.

8Passengers should also observe

the above precautions.

Modifications

Modifications made to this scooter not

approved byYamaha, or the removal of

original equipment, may render the

scooter unsafe for use and may cause

severe personal injury. Modifications

may also make your scooter illegal to

use.

Loading and accessories

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 accesso-

ries to your scooter. Use extra care when

riding a scooter that has added cargo or

accessories. Here are some general

guidelines to follow if loading cargo or

adding accessories to your scooter:

5ML-F8199-E0ch1re.pmd 2003/12/12, 16:022

1-3

QSAFETY INFORMATION

The total weight of the operator, passen-

ger, accessories and cargo must not ex-

ceed the maximum load limit of 170 kg

(374 lb).When loading within this weight

limit, keep the following in mind:

8Cargo and accessory weight should

be kept as low and close to the

scooter as possible. Make sure to

distribute the weight as evenly as

possible on both sides of the

scooter to minimize imbalance or

instability.

8Shifting weights can create a sud-

den imbalance. Make sure that ac-

cessories and cargo are securely

attached to the scooter before riding.

Check accessory mounts and

cargo restraints frequently.

8Never attach any large or heavy

items to the handlebar, front fork,

or front fender. Such items can cre-

ate unstable handling or a slow

steering response.

Accessories

Genuine Yamaha accessories have

been specifically designed for use on

this scooter. Since Yamaha cannot test

all other accessories that may be avail-

able, you must personally be responsible

for the proper selection, installation and

use of non-Yamaha accessories. Use

extreme caution when selecting and in-

stalling any accessories.

Keep the following guidelines in mind,

as well as those provided under “Load-

ing” when mounting accessories.

8Never install accessories or carry

cargo that would impair the perfor-

mance of your scooter. Carefully

inspect the accessory before us-

ing it to make sure that it does not

in any way reduce ground clear-

ance or cornering clearance, limit

suspension travel, steering travel

or control operation, or obscure

lights or reflectors.

9Accessories 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.

9Bulky 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.

9Certain 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 recom-

mended.

8Use caution when adding electrical

accessories. If electrical accesso-

ries exceed the capacity of the

scooter’s electrical system an elec-
