SAFETY INFORMATION

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
MAINTENANCE
REQUIREMENTS IN THE OWNER’S MANUAL.
● OBTAIN QUALIFIED TRAINING
IN SAFE AND PROPER RIDING
TECHNIQUES.
● OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL
AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.
Safe riding
● Always
make
pre-operation
checks. Careful checks may help
prevent an accident.
● This scooter is designed to carry
the operator and 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 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.
1-1
●
●
Many accidents involve inexperienced 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.
SAFETY INFORMATION
●
●
●
• 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 footboard 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 onroad 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 which 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.
● Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
● Passengers should also observe
the above precautions.
1-2
Modifications
Modifications made to this scooter not
approved by Yamaha, 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 accessories 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:
Loading
The total weight of the operator, passenger, accessories and cargo must
not exceed the maximum load limit of
185 kg (408 lb). When loading within
this weight limit, keep the following in
mind:
1
SAFETY INFORMATION
●
1
Cargo 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.
● Shifting weights can create a sudden imbalance. Make sure that accessories and cargo are securely
attached to the scooter before
riding. Check accessory mounts
and cargo restraints frequently.
● 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.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test
all other accessories that may be available, you must personally be responsible for the proper selection, installation
and use of non-Yamaha accessories.
Use extreme caution when selecting
and installing any accessories.
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.
• 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
1-3
●
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 electrical 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.
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMABLE:
• Always turn the engine off when
refueling.
• Take care not to spill any gasoline on the engine or exhaust
system when refueling.
• Never refuel while smoking or in
the vicinity of an open flame.
SAFETY INFORMATION
●
●
●
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
scooter in an area that has adequate ventilation.
Always turn the engine off before
leaving the scooter unattended
and remove the key from the main
switch. When parking the scooter,
note the following:
• The engine and exhaust system
may be hot, therefore, park the
scooter in a place where pedestrians or children are not likely to
touch these hot areas.
• Do not park the scooter on a
slope or soft ground, otherwise it
may fall over.
• Do not park the scooter near a
flammable source (e.g., a kerosene heater, or near an open
flame), otherwise it could catch
fire.
If you should swallow any gasoline, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.

●
●
●
●
1-4
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 could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.

PRE-OPERATION CHECKS
EAU15591
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.

Checking the spark plug
6
The spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode, it
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.
The porcelain insulator around the center electrode of the spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally). If
the spark plug shows a distinctly different color, the engine could be defective. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the vehicle.
If the spark plug shows signs of electrode erosion and excessive carbon or
other deposits, it should be replaced.
Specified spark plug:
NGK / BR8HS
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.

brake shoe wear without having to disassemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.

Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
● When checking the fluid level,
make sure that the top of the master cylinder is level by turning the
handlebars.
● Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking performance.
Recommended brake fluid:
DOT 3 or 4

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,

Cleaning
ECA10780
CAUTION:
●
●
●
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
windshields, cowlings, panels
and other plastic parts. Use only
a soft, clean cloth or sponge
with mild detergent and water to
clean plastic.
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 washers 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.
SCOOTER CARE AND STORAGE
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.
NOTE:
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.
ECA10790
CAUTION:
Do not use warm water since it increases the corrosive action of the
salt.
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.
EWA10940
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.)
3. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal,
including chrome- and nickel-plated, surfaces.
4. Use spray oil as a universal cleaner to remove any remaining dirt.
