SAFETY INFORMATION
Safe riding
● Always make pre-operation
1
checks. Careful checks may help
prevent an accident.
● This motorcycle is designed for off-
road use only, therefore, it is illegal
to operate it on public streets,
roads, or highways, even a dirt or
gravel one. Off-road use on public
lands may be illegal. Please check
local regulations before riding.
● This motorcycle is designed to car-
ry the operator only. No passengers.
● Many accidents involve inexperi-
enced operators.
• Make sure that the operator is
qualified and that you only lend
your motorcycle to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
● 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 un-
EAU39313
dercornering (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 accident.
● The posture of the operator is im-
portant for proper control. The operator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the motorcycle.
● 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 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.
● 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.
● 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.
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.

SAFETY INFORMATION
Loading and accessories
Adding accessories 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 accessories to
your motorcycle. Use extra care when
riding a motorcycle that has added accessories. Here are some general
guidelines to follow if adding accessories to your motorcycle:
Loading
● The weight of the operator must
not exceed 40 kg (88 lb).
● Accessory weight should be kept
as low and close to the motorcycle
as possible. Make sure to distribute the weight as evenly as possible on both sides of the motorcycle
to minimize imbalance or instability.
● Shifting weights can create a sud-
den imbalance. Make sure that accessories are securely attached to
the motorcycle before riding.
Check accessory mounts frequently.
● Never attach any large or heavy
items to the handlebar, front fork,
or front fender.
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 these guidelines in mind for
mounting accessories in addition to
those provided under “Loading”.
● Never install accessories or 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 suspen-
sion travel, steering travel or con-
trol operation.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper
1-2
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.
• Bulky 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.
• Certain 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.
● Use caution when adding electri-
cal 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
engine power.

SAFETY INFORMATION
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
1
• Always turn the engine off when
refueling.
• Take care not to spill any gasoline on the engine or exhaust
pipe(s)/muffler(s) when refueling.
• Never refuel while smoking or in
the vicinity of an open flame.
● 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.
● 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:
• The engine and exhaust pipe(s)/
muffler(s) may be hot, therefore,
park the motorcycle in a place
where pedestrians or children
are not likely to touch these hot
areas.
• Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.
• Do not park the motorcycle near
a flammable source (e.g., a kerosene heater, or near an open
flame), otherwise it could catch
fire.
● When transporting the motorcycle
in another vehicle, make sure that
it is kept upright and that the fuel
cock(s) are turned to “ON” or
“RES” (for vacuum type)/“OFF”
(for manual type). If the motorcycle
should lean over, gasoline may
leak out of the carburetor or fuel
tank.
● If you should swallow any gaso-
line, 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.
