• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac- tice riding your vehicle where
there is no traffic until you have
become thoroughly familiar with
the vehicle and all of its con-
trols.
 Many accidents have been
caused by error of the vehicle op-
erator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-
cornering (insufficient lean angle
for the speed).
• Always obey the speed limit and never travel faster than warrant-
ed by road and traffic condi-
tions.
• 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 foot-
rests during operation to main-
tain control of the vehicle.
• 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 vehicle is designed for on-
road use only. It is not suitable for
off-road use.
Protective Apparel
The majority of fatalities from scooter
and motorcycle accidents are the re-
sult 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 ef-
fective 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 sys-
tem become very hot during or af-
ter operation and can cause
burns.
 A passenger should also observe
the above precautions.
Avoi d Car bon Monoxi de Poisonin g
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.

1Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be pres-
ent even if you do not see or smell any
engine exhaust. Deadly levels of car-
bon monoxide can collect rapidly and
you can quickly be overcome and un-
able to save yourself. Also, deadly lev-
els of carbon monoxide can linger for
hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
 Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
 Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
 Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors. Loa
din g
Adding accessories or cargo to your
vehicle can adversely affect stability
and handling if the weight distribution
of the vehicle is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or acces-
sories to your vehicle. Use extra care
when riding a vehicle that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your vehicle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloa ded vehicle
coul d cause an acci dent.
When loading within this weight limit,
keep the following in mind:  Cargo and accessory weight
should be kept as low and close to
the vehicle as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos- sible and make sure to distribute
the weight as evenly as possible
on both sides of the vehicle to
minimize imbalance or instability.
 Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the vehicle be-
fore riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure 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 desi gne d to
pull a trailer or to be attached to
a si decar.

able 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 ac-
cessories 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 en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories, an
d
Mo difications
While you may find aftermarket prod-
ucts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries 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 “Load-
ing” when mounting accessories.
 Never install accessories or carry
cargo that would impair the per-
formance of your vehicle. Careful-
ly 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 reflectors.
• Accessories fitted 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 vehicle due to aerodynamic
effects. Wind may attempt to lift the vehicle, or the vehicle 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 accesso-
ries are not recommended.
 Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the vehicle’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Aftermarket Tires an d Rims
The tires and rims that came with your
vehicle 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

specifications and more information on
replacing your tires.
Transportin
g the Vehicle
Be sure to observe the following in-
structions before transporting the vehi-
cle in another vehicle.  Remove all loose items from the
vehicle.
 Point the front wheels straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Secure the vehicle with tie-downs
or suitable straps that are at-
tached to solid parts of the vehi-
cle, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars 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 tie-
downs, if possible, so that the ve-
hicle will not bounce excessively
during transport.
EAU60590
Further safe-ri din g points Be sure to signal clearly when
making turns.
 Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the vehicle 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 be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the vehicle up-
right, otherwise it could slide out
from under you.
 The brake pads or linings could
get wet when you wash the vehi-
cle. After washing the vehicle,
check the brakes before riding.

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