typical error made by the operator
is veering wide on a turn due to
excessive speed or undercornering
(insufficient lean angle for the
speed).
Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
●
The 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
footrests during operation to
maintain control of the scooter.
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 unlesshe or she can firmly place both
feet on the passenger foot-
rests.
●
Never ride under the influence of
alcohol or other drugs.
●
This scooter is designed for on-road
use only. It is not suitable for off-
road use.
Protective apparel
The majority of fatalities from scooter
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 con-
tribute to an impairment of vision
that could delay seeing a hazard.
●
The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or reducing
abrasions or lacerations.
●
Never wear loose-fitting clothes,
otherwise they could catch on thecontrol levers or wheels and cause
injury or an accident.
●
Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust system
become very hot during or after
operation and can cause burns.
●
A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
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 un-
able to save yourself. Also, deadly lev-
els of carbon monoxide can linger for
hours or days in enclosed or poorly ven-
tilated areas. If you experience any

symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.●
Do 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.
●
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●
Do 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
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso-
ries to your scooter. Use extra care whenriding a scooter that has added cargo or
accessories. Here, along with the infor-
mation about accessories below, are
some general guidelines to follow if load-
ing cargo to your scooter:
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.
Maximum load:
177 kg (390 lb)When loading within this weight limit,
keep the following in mind:●
Cargo and accessory weight should
be kept as low and close to the
scooter as possible. Securely pack
your heaviest items as close to the
center of the vehicle as possible
and make sure to distribute the
weight as evenly as possible on
both sides of the scooter to mini-
mize imbalance or instability.
●
Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the scooter before riding.
Check accessory mounts and
cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-
adjustable models only), and
check the condition and
pressure 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.
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.

is an important decision. Genuine

Further safe-riding points●
Make sure to signal clearly when
making turns.
●
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when stop-
ping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
●
Be careful when passing parked
cars. A driver might not see you and
open a door in your path.
●
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers become
extremely slippery when wet. Slow
down and cross them with caution.
Keep the scooter upright, otherwise
it could slide out from under you.
●
The brake lining could get wet when
you wash the scooter. After wash-
ing the scooter, check the brakes
before riding.
●
Always wear a helmet, gloves, trou-
sers (tapered around the cuff and
ankle so they do not flap), and a
bright colored jacket.
●
Do not carry too much luggage on
the scooter. An overloaded scooter
is unstable.

Safe-riding points
tric failure could result, which could
cause a dangerous loss of lights or
engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, sizes,
and combinations may not be appropri-
ate. Refer to page 6-12 for tire specifi-
cations and more information on replac-
ing your tires.
