Safety information
1-2
1• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your vehicle where
there is no traffic until you have
become thoroughly familiar with
the vehicle and all of its con-
trols.
zMany accidents have been
caused by error of the vehicle op-
erator. A typical error made by the
operator is veering wide on a turn
due to excessive speed or under-
cornering (insufficient lean angle
for the speed).
• Always obey the speed limit and
never travel faster than warrant-
ed by road and traffic condi-
tions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
zThe posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator foot-
rests during operation to main-
tain control of the vehicle.
• The 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.
Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.
zNever ride under the influence of
alcohol or other drugs. zThis vehicle is designed for on-
road use only. It is not suitable for
off-road use.
Protective Apparel
The majority of fatalities from scooter
and motorcycle accidents are the re-
sult of head injuries. The use of a safety
helmet is the single most critical factor
in the prevention or reduction of head
injuries.
zAlways wear an approved helmet.
zWear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.
zThe use of a jacket, substantial
shoes, trousers, gloves, etc., is ef-
fective in preventing or reducing
abrasions or lacerations.
zNever wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.
zAlways wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause
burns.
zA passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.

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.)
