SAFETY INFORMATION
2-2

●
Many accidents involve inexperi-
enced operators. Make sure that you are qualified and 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). Never travel faster
than warranted by conditions.
●
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.
●
Be sure the transmission is in neu-
tral before starting the engine.
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
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.

vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.

proper tire pressure may cause se-
vere injury or death from loss of
