SAFETY INFORMATION
1-2
1
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 footboard 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 unless
he or she can firmly place both
feet on the passenger footrests.
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 inju-ries. The use of a safety helmet is the
single most critical factor in the preven-
tion 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 which could delay seeing
a hazard.
The use of a jacket, substantial
shoes, trousers, gloves, etc., is ef-
fective in preventing or reducing
abrasions or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers 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 protec-
tive clothing that covers your legs,
ankles, and feet.
Passengers should also observe
the above precautions.
Modifications
Modifications made to this scooter notapproved by Yamaha, 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:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Maximum load:

Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final transmis-
sion oil must be changed as follows at
the intervals specified in the periodic
maintenance and lubrication chart.
1. Start the engine, warm up the final
transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the center-
stand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the oil filler cap and drain
bolt to drain the oil from the final
transmission case.5. Install the final transmission oil
drain bolt, and then tighten it to the
specified torque.6. Add the specified amount of the
recommended final transmission
oil, and then install and tighten the
oil filler cap.
WARNING
EWA11310
Make sure that no foreign mate-
rial enters the final transmission
case.
Make sure that no oil gets on the
tire or wheel.
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.

WARNING
EWA10470
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
EAU21960
Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
wheel must be replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
EAU22170
Adjusting the rear brake lever
free play
The brake lever free play should mea-
sure 10–20 mm (0.39–0.79 in) as
shown. Periodically check the brake le-
ver free play and, if necessary, adjust it
as follows.
To increase the brake lever free play,
turn the adjusting nut at the brake shoe
plate in direction (a). To decrease the
brake lever free play, turn the adjusting
nut in direction (b).
