SAFETY INFORMATION
Aftermarket Parts, Accessories,
and Modi cations
While you may fi nd aftermarket prod-
ucts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries or modifi cations are not suitable
because of potential safety hazards
to you or others. Installing aftermarket
products or having other modifi cations
performed to your vehicle that change
any of the vehicle’s design or opera-
tion characteristics can put you and
others at greater risk of serious injury
or death. You are responsible for inju-
ries related to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under
“Loading” when mounting accesso-
ries.●
Never install accessories or carry
cargo that would impair the per-
formance of your scooter. Care-
fully 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 ob-
scure lights or refl ectors.
• Accessories fi tted to the han-
dlebar or the front fork area can
create instability due to improp-
er weight distribution or aerody-
namic 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 dis-
place 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 acces-sories are not recommended.
●
Use caution when adding electri-
cal accessories. If electrical ac-
cessories 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 pro-
vide 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 specifi cations and more informa-
tion on replacing your tires.
Transporting the Scooter
Be sure to observe following instruc-
tions 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

2. Do not overfi ll the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank fi ll-
er hole. Stop fi lling when the fuel
reaches the bottom of the fi ller
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.
3. Wipe up any spilled fuel im-
mediately.
NOTICE:
Immedi-
ately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel
may deteriorate painted sur-
faces or plastic parts.[ECA10071]
4. Be sure to securely close the fuel
tank cap.
EWA15151
WARNING
Gasoline is poisonous and can
cause injury or death. Handle
gasoline with care. Never siphon
gasoline by mouth. If you should
swallow some gasoline or inhale a
lot of gasoline vapor, or get some
gasoline in your eyes, see your
doctor immediately. If gasoline
spills on your skin, wash with soap
and water. If gasoline spills on your
clothing, change your clothes.
EAU33520
Recommended fuel:
REGULAR UNLEADED GASO-
LINE ONLY
Fuel tank capacity:
7.4 L (1.96 US gal) (1.63 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 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.

WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible re 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
system has cooled down be-
fore 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.
