1 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 poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.
zDo not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
zDo not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
zDo not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
vehicle can adversely affect stability
and handling if the weight distribution
of the vehicle is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or acces-
sories to your vehicle. Use extra care
when riding a vehicle that has added
cargo or accessories. Here, along with
the information about accessories be-
low, are some general guidelines to fol-
low if loading cargo to your vehicle:The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
When loading within this weight limit,
keep the following in mind:
zCargo and accessory weight
should be kept as low and close to
the vehicle as possible. Securely
pack your heaviest items as close
to the center of the vehicle as pos-
sible and make sure to distribute
the weight as evenly as possible
on both sides of the vehicle to
minimize imbalance or instability.
zShifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the vehicle be-
fore riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension
for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• Never attach any large or heavy
items to the handlebar, front
fork, or front fender. Such items
can create unstable handling or
a slow steering response.
zThis vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Maximum load:
167 kg (368 lb)

1 Aftermarket Tires and Rims
The tires and rims that came with your
vehicle were designed to match the
performance capabilities and to pro-
vide the best combination of handling,
braking, and comfort. Other tires, rims,
sizes, and combinations may not be
appropriate. Refer to page 6-17 for tire
specifications and more information on
replacing your tires.
Transporting the Vehicle
Be sure to observe the following in-
structions before transporting the vehi-
cle in another vehicle.
zRemove all loose items from the
vehicle.
zPoint the front wheels straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
zSecure the vehicle with tie-downs
or suitable straps that are at-
tached to solid parts of the vehi-
cle, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.
zThe suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the ve-
hicle will not bounce excessively
during transport.
EAU60590
Further safe-riding points
zBe sure to signal clearly when
making turns.
zBraking can be extremely difficult
on a wet road. Avoid hard braking,
because the vehicle could slide.
Apply the brakes slowly when
stopping on a wet surface.
zSlow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
zBe careful when passing parked
cars. A driver might not see you
and open a door in your path.
zRailroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the vehicle up-
right, otherwise it could slide out
from under you.
zThe brake pads or linings could
get wet when you wash the vehi-
cle. After washing the vehicle,
check the brakes before riding.
zAlways wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a brightly colored jacket.
zDo not carry too much luggage on
the vehicle. An overloaded vehicle
is unstable. Use a strong cord to
secure any luggage to the carrier
(if equipped). A loose load will af-
fect the stability of the vehicle and
could divert your attention from
the road. (See page 1-3.)

ABS (for ABS models)
Your leaning multi-wheel vehicle’s ABS
(Anti-lock Brake System) features an
electronic control system, which acts
on each of the front and rear brakes in-
dependently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situa-
tion, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking ef-
fectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
zThe ABS performs best with
long braking distances.
zOn certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.
The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIP
zThe ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from the
front of the vehicle, and if either
brake lever is even slightly ap-
plied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.zThis ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. How-
ever, special tools are required, so
please consult your Yamaha deal-
er.
NOTICE

WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gasoline
by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in
your eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU76750
NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
TIP
zThis mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
zCheck that gasoline nozzle has
the same identifier when fueling.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
Recommended fuel:
Regular unleaded gasoline (Gasohol
[E10] acceptable)
Fuel tank capacity:
7.2 L (1.9 US gal, 1.6 Imp.gal)
