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.

SAFETY INFORMATION
l
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are
poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has
adequate ventilation.
l
Always turn the engine off before
leaving the motorcycle unattended
and remove the key from the main
switch. When parking the
motorcycle, note the following:lThe engine and exhaust system
may be hot, therefore, park the
motorcycle in a place where
pedestrians or children are not
likely to touch these hot areas.lDo not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.lDo not park the motorcycle near
a flammable source, (e.g., a
kerosene heater, or near an open
flame), otherwise it could catch
fire.
l
When transporting the motorcycle
in another vehicle, make sure that
it is kept upright. If the motorcycleshould lean over, gasoline may leak
out of the fuel tank.
l
If you should swallow any gasoline,
inhale a lot of gasoline vapor, or
allow gasoline to get into your eyes,
see your doctor immediately. If any
gasoline spills on your skin or
clothing, immediately wash the
affected area with soap and water
and change your clothes.
