QSAFETY INFORMATION
EAU10260
SCOOTERS ARE SINGLE TRACK VE-
HICLES. THEIR SAFE USE AND OP-
ERATION ARE DEPENDENT UPON
THE USE OF PROPER RIDING TECH-
NIQUES AS WELL AS THE EXPER-
TISE OF THE OPERATOR. EVERY OP-
ERATOR SHOULD KNOW THE FOL-
LOWING REQUIREMENTS BEFORE
RIDING THIS SCOOTER.
HE OR SHE SHOULD:
8OBTAIN THOROUGH INSTRUC-
TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
SCOOTER OPERATION.
8OBSERVE THE WARNINGS AND
MAINTENANCE REQUIRE-
MENTS IN THE OWNER’S
MANUAL.
8OBTAIN QUALIFIED TRAINING IN
SAFE AND PROPER RIDING
TECHNIQUES.
8OBTAIN PROFESSIONAL TECH-
NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL AND/
OR WHEN MADE NECESSARY
BY MECHANICAL CONDITIONS.
Safe riding
8Always make pre-operation checks.
Careful checks may help prevent
an accident.
8This scooter is designed to carry
the operator and passenger.
8The failure of motorists to detect
and recognize scooters in traffic is
the predominating cause of auto-
mobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself con-
spicuous appears to be very effec-
tive in reducing the chance of this
type of accident.
Therefore:
9Wear a brightly colored jacket.
9Use extra caution when
approaching and passing
through intersections, since
intersections are the most
likely places for scooter
accidents to occur.
9Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
8Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent driver’s license.
9Make sure that you are quali-
fied and that you only lend your
scooter to other qualified
operators.
9Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
9We recommend that you
practice riding your scooter
where there is no traffic until
you have become thoroughly
familiar with the scooter and all
of its controls.
Many accidents have been caused
by error of the scooter operator. A
typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).
9Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.

9Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
8The posture of the operator and
passenger is important for proper
control.
9The operator should keep both
hands on the handlebar and
both feet on the footboard
during operation to maintain
control of the scooter.
9The 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 foot-
rests.
9Never carry a passenger unless
he or she can firmly place both
feet on the passenger foot-
rests.
8Never 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.
8Always wear an approved helmet.
8Wear a face shield or goggles.Wind
in your unprotected eyes could con-
tribute to an impairment of vision
which could delay seeing a hazard.
8The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or reducing
abrasions or lacerations.
8Never wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.
8Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protec-
tive clothing that covers your legs,
ankles, and feet.
8Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter not
approved by MBK, or the removal of
original equipment, may render the
scooter unsafe for use and may cause
severe personal injury. Modifications
may also make your scooter illegal to
use.
Loading and accessories
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 when
riding a scooter that has added cargo or
accessories. Here are some general
guidelines to follow if loading cargo or
adding accessories to your scooter:

QSAFETY INFORMATION
Loading
The total weight of the operator, passen-
ger, accessories and cargo must not ex-
ceed the maximum load limit of 170 kg
(374 lb).When loading within this weight
limit, keep the following in mind:
8Cargo and accessory weight should
be kept as low and close to the
scooter as possible. Make sure to
distribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance or
instability.
8Shifting 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.
8Never attach any large or heavy
items to the handlebar, front fork,
or front fender. Such items can cre-
ate unstable handling or a slow
steering response.
Accessories
Genuine MBK accessories have been
specifically designed for use on this
scooter. Since MBK cannot test all other
accessories that may be available, you
must personally be responsible for the
proper selection, installation and use of
non-MBK accessories. Use extreme
caution when selecting and installing
any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.
8Never install accessories or carry
cargo that would impair the perfor-
mance of your scooter. Carefully
inspect the accessory before us-
ing it to make sure that it does not
in any way reduce ground clear-
ance or cornering clearance, limit
suspension travel, steering travel
or control operation, or obscure
lights or reflectors.
9Accessories 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.
9Bulky or large accessories may
seriously affect the stability of
the scooter due to aerodynamic
effects. Wind may attempt to
lift the scooter, or the scooter
may become unstable in cross
winds. These accessories may
also cause instability when
passing or being passed by
large vehicles.
9Certain 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 recom-
mended.
8Use caution when adding electrical
accessories. If electrical accesso-
ries exceed the capacity of the
scooter’s electrical system an elec-

QSAFETY INFORMATION
tric failure could result, which could
cause a dangerous loss of lights or
engine power.
Gasoline and exhaust gas
8GASOLINE IS HIGHLY FLAM-
MABLE:
9Always turn the engine off
when refueling.
9Take care not to spill any
gasoline on the engine or
exhaust system when refueling.
9Never refuel while smoking or
in the vicinity of an open flame.
8Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of con-
sciousness and death within a
short time. Always operate your
scooter in an area that has adequate
ventilation.
8Always turn the engine off before
leaving the scooter unattended and
remove the key from the main
switch. When parking the scooter,
note the following:
9The engine and exhaust
system may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.
9Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
9Do not park the scooter near a
flammable source (e.g., a
kerosene heater, or near an
open flame), otherwise it could
catch fire.
8If 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 cloth-
ing, immediately wash the affected
area with soap and water and
change your clothes.

8Braking 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.
8Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
8Be careful when passing parked
cars. A driver might not see you and
open a door in your path.
8Railroad 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.
8The brake pads could get wet when
you wash the scooter. After wash-
ing the scooter, check the brakes
before riding.
8Always wear a helmet, gloves, trou-
sers (tapered around the cuff and
ankle so they do not flap), and a
bright colored jacket.
8Do not carry too much luggage on
the scooter. An overloaded scooter
is unstable.
