SAFETY INFORMATION
motorist’s blind spot.
Never maintain a motorcycle without proper knowledge. Con-
tact an authorized motorcycle
dealer to inform you on basic
motorcycle maintenance. Cer-
tain maintenance can only be
carried out by certified staff.

Many accidents involve inexperi-
enced operators.
Make sure that you are qualifiedand that you only lend your mo-
torcycle to other qualified opera-
tors.
Know your skills and limits. Staying within your limits may
help you to avoid an accident.
We recommend that you prac- tice riding your motorcycle until
you have become thoroughly fa-
miliar with the motorcycle and all
of its controls.

Many accidents have been caused
by error of the motorcycle opera-
tor. A typical error made by the op-
erator 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 conditions.
Always signal before turning or changing lanes. Make sure that
other motorists can see you.

Ride cautiously in unfamiliar ar-
eas. You may encounter hidden
obstacles that could cause an ac-
cident.

The posture of the operator is im-
portant for proper control. The op-
erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the motorcy-
cle.

Never ride under the influence of
alcohol or other drugs.
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 preven-
tion 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 abrasions
or lacerations.

Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, 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.
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
present 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

Fuel tank breather hose Before operating the motorcycle:
Check the fuel tank breather hose
connection.

Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.

Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.
TIPIf the fuel tank breather hose falls out,
reinstall it on the fuel tank cap with the
arrow mark on the one-way valve point-ed downward as shown.
EAU13433
Catalytic converter This model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire 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 sys-
tem has cooled down before do-
ing any maintenance work.

Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE

Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic

PERIODIC MAINTENANCE AND ADJUSTMENT
EAU17244
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However, de-
pending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
