SAFETY INFORMATION
EAU10281
MOTORCYCLES ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
OPERATION ARE DEPENDENT UPON
THE USE OF PROPER RIDING
TECHNIQUES AS WELL AS THE
EXPERTISE OF THE OPERATOR.
EVERY OPERATOR SHOULD KNOW
THE FOLLOWING REQUIREMENTS
BEFORE RIDING THIS MOTORCYCLE.
HE OR SHE SHOULD:l
OBTAIN THOROUGH
INSTRUCTIONS FROM A
COMPETENT SOURCE ON ALL
ASPECTS OF MOTORCYCLE
OPERATION.
l
OBSERVE THE WARNINGS AND
MAINTENANCE
REQUIREMENTS IN THE
OWNER’S MANUAL.
l
OBTAIN QUALIFIED TRAINING IN
SAFE AND PROPER RIDING
TECHNIQUES.
l
OBTAIN PROFESSIONAL
TECHNICAL SERVICE AS
INDICATED BY THE OWNER’S
MANUAL AND/OR WHEN MADE
NECESSARY BY MECHANICAL
CONDITIONS.Safe riding
l
Always make pre-operation checks.
Careful checks may help prevent
an accident.
l
This motorcycle is designed to
carry the operator and a passenger.
l
The failure of motorists to detect
and recognize motorcycles in traffic
is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did not
see the motorcycle. Making
yourself conspicuous appears to be
very effective in reducing the
chance of this type of accident.
Therefore:lWear a brightly colored jacket.lUse extra caution when you are
approaching and passing through
intersections, since intersections
are the most likely places for
motorcycle accidents to occur.lRide where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
l
Many accidents involve
inexperienced operators. In fact, many operators who have been
involved in accidents do not even
have a current motorcycle license.
lMake sure that you are qualified
and that you only lend your
motorcycle to other qualified
operators.lKnow your skills and limits.
Staying within your limits may
help you to avoid an accident.lWe recommend that you
practice riding your motorcycle
where there is no traffic until you
have become thoroughly familiar
with the motorcycle and all of its
controls.
l
Many accidents have been caused
by error of the motorcycle operator.
A typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).lAlways obey the speed limit and
never travel faster than warranted
by road and traffic conditions.lAlways signal before turning or
changing lanes. Make sure that
other motorists can see you.

SAFETY INFORMATION
l
The posture of the operator and
passenger is important for proper
control.lThe operator should keep both
hands on the handlebar and both
feet on the operator footrests
during operation to maintain
control of the motorcycle.lThe 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.lNever carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.
l
Never ride under the influence of
alcohol or other drugs.
l
This motorcycle is designed for on-
road use only. It is not suitable for
off-road use.
Protective apparel
The majority of fatalities from
motorcycle accidents are the result of
head injuries. The use of a safety helmet
is the single most critical factor in the
prevention or reduction of head injuries.
l
Always wear an approved helmet.
l
Wear a face shield or goggles. Wind
in your unprotected eyes could
contribute to an impairment of
vision that could delay seeing a
hazard.
l
The use of a jacket, heavy boots,
trousers, gloves, etc., is effective
in preventing or reducing abrasions
or lacerations.
l
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.
l
Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear
protective clothing that covers your
legs, ankles, and feet.
l
A passenger should also observe
the above precautions.
Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the removal
of original equipment, may render the
motorcycle unsafe for use and may
cause severe personal injury.
Modifications may also make your motorcycle illegal to use.
Loading and accessories
Adding accessories or cargo to your
motorcycle can adversely affect stability
and handling if the weight distribution of
the motorcycle is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle that
has added cargo or accessories. Here
are some general guidelines to follow if
loading cargo or adding accessories to
your motorcycle:
Loading
The total weight of the operator,
passenger, accessories and cargo must
not exceed the maximum load limit.Maximum load:
167 kg (368 lb)When loading within this weight limit,
keep the following in mind:l
Cargo and accessory weight should
be kept as low and close to the
motorcycle as possible. Make sure
to distribute the weight as evenly
