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
footrests during operation to
maintain control of the motorcy-
cle.
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 un-
less he or she can firmly place
both feet on the passenger
footrests.
●Never ride under the influence of
alcohol or other drugs.
2-2
Protective apparel
The majority of fatalities from motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is the
single most critical factor in the pre-
vention 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, heavy boots,
trousers, gloves, etc., is effective
in preventing or reducing abra-
sions or lacerations.
●Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or
wheels and cause injury or an ac-
cident.
●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.Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be pre-
sent even if you do not see or smell any
engine exhaust. Deadly levels of carbon
monoxide can collect rapidly and you
can quickly be overcome and unable to
save yourself. Also, deadly levels of car-
bon monoxide can linger for hours or
days in enclosed or poorly ventilated ar-
eas. If you experience any symptoms of
carbon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.
●Do not run engine indoors. Even if
you try to ventilate engine ex-
haust with fans or open windows
and doors, carbon monoxide can
rapidly reach dangerous levels.
●Do not run engine in poorly ventilat-
ed or partially enclosed areas such
as barns, garages, or carports.
●Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.

SAFETY INFORMATION
products or having other modifications
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 in-
juries related to changes in the vehi-
cle.
Keep the following guidelines in mind,
as well as those provided under
"Loading" when mounting acces-
sories.
●Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. 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 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 aslightweight as possible and
should be kept to a minimum.
Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerody-
namic effects. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become
unstable in cross winds. These
accessories may also cause in-
stability 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 motorcycle's electrical sys-
tem, an electric failure could re-
sult, which could cause a danger-
ous loss of lights or engine power.Aftermarket Tires and Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
7-16 for tire specifications and more
information on replacing your tires.
