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

SAFETY INFORMATION
as possible on both sides of the
motorcycle to minimize imbalance
or instability.
l
Shifting weights can create a
sudden imbalance. Make sure that
accessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
l
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items,
including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha cannot
test all other accessories that may be
available, you must personally be
responsible for the proper selection,
installation and use of non-Yamaha
accessories. Use extreme caution when
selecting and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under“Loading” when mounting accessories.
l
Never install accessories or carry
cargo that would impair the
performance of your motorcycle.
Carefully 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
obscure lights or reflectors.lAccessories fitted to the
handlebar or the front fork area
can create instability due to
improper weight distribution or
aerodynamic 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.lBulky or large accessories may
seriously affect the stability of the
motorcycle due to aerodynamic
effects. Wind may attempt to lift
the motorcycle, or the motorcycle
may become unstable in cross
winds. These accessories may
also cause instability whenpassing or being passed by large
vehicles.
lCertain accessories can displace
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
accessories are not
recommended.
l
Use caution when adding electrical
accessories. If electrical
accessories exceed the capacity of
the motorcycle’s electrical system,
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
l
GASOLINE IS HIGHLY
FLAMMABLE:lAlways turn the engine off when
refueling.lTake care not to spill any gasoline
on the engine or exhaust system
when refueling.lNever refuel while smoking or in
the vicinity of an open flame.

overload the engine as well as other
vital parts of the motorcycle and can
lead to chain slippage or breakage.
To prevent this from occurring, keep
the drive chain slack within the
specified limits.3. Tighten both locknuts and the axle
nut to the specified torques.
