SAFETY INFORMATION

Be a Responsible Owner
As the vehicle’s owner, you are responsible for the safe and proper operation of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are
dependent upon the use of proper
riding techniques as well as the
expertise of the operator. Every operator should know the following requirements before riding this scooter.
He or she should:
G Obtain thorough instructions
from a competent source on all
aspects of scooter operation.
G Observe the warnings and maintenance requirements in this
Owner’s Manual.
G Obtain qualified training in safe
and proper riding techniques.
G Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary by mechanical
conditions.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle to
make sure it is in safe operating condition. Failure to inspect or maintain
the vehicle properly increases the
possibility of an accident or equipment damage. See page 4-1 for a list
of pre-operation checks.
G This scooter is designed to carry
the operator and a passenger.
G
TIP
Although this scooter is designed to
carry a passenger, always comply
with the local regulations.
G
The failure of motorists to detect
and recognize scooters in traffic
is the predominating cause of
automobile/scooter accidents.
Many accidents have been caused by an automobile driver who
did not see the scooter. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you
are approaching and passing
through intersections, since
1-1
G
intersections are the most
likely places for scooter accidents to occur.
• Ride where other motorists can
see you. Avoid riding in another motorist’s blind spot.
Many accidents involve inexperienced operators. In fact, many
operators who have been involved in accidents do not even
have a current driver’s license.
• Make sure that you are qualified and that you only lend your
scooter to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We 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 under-

cornering (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
unless he or she can firmly place both feet on the passenger
footrests.
Never ride under the influence of
alcohol or other drugs.
G
This scooter is designed for onroad 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.
G Always wear an approved helmet.
G Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment of vision that could delay
seeing a hazard.
G The use of a jacket, substantial
shoes, trousers, gloves, etc., is
effective in preventing or reducing abrasions or lacerations.
G Never wear loose-fitting clothes,
otherwise they could catch on
the control levers or wheels and
cause injury or an accident.
G Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust system become very hot during or
1-2
after operation and can cause
burns.
G A 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 headaches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless,
odorless, 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 poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.

SAFETY INFORMATION
G
1
Do not run engine indoors. Even
if you try to ventilate engine
exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous
levels.
G Do not run engine in poorly ventilated or partially enclosed areas
such as barns, garages, or carports.
G 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 accessories to your scooter. Use
extra care when riding a scooter that
has added cargo or accessories.
Here, along with the information
about accessories below, are some
general guidelines to follow if loading
cargo to your scooter:
The total weight of the operator, passenger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
Maximum load:
CS50 169 kg (373 lb)
CS50M 169 kg (373 lb)
CS50Z 166 kg (366 lb)
When loading within this weight limit,
keep the following in mind:
G 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 minimize imbalance or
instability.
G Shifting weights can create a
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the scooter
before riding. Check accessory
mounts and cargo restraints frequently.
1-3
G
Properly adjust the suspension
for your load (suspension-adjustable models only), and check the
condition and pressure of your
tires.
G 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.
G This vehicle is not designed to
pull a trailer or to be attached
to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are available only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and
accessories or offer other modifications for Yamaha vehicles. Yamaha is
not in a position to test the products
that these aftermarket companies
produce. Therefore, Yamaha can neither endorse nor recommend the use
of accessories not sold by Yamaha or
49D-F819D-E0
18/12/08
16:56
Página 11
SAFETY INFORMATION
modifications not specifically recommended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket products similar in design and quality to
genuine Yamaha accessories, recognize that some aftermarket accessories or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifications performed to your vehicle that
change any of the vehicle’s design or
operation characteristics can put you
and others at greater risk of serious
injury or death. You are responsible
for injuries related to changes in the
vehicle.
Keep the following guidelines in mind,
as well as those provided under “Loading” when mounting accessories.
G Never install accessories or carry
cargo that would impair the performance of your scooter. Carefully inspect the accessory before using it to make sure that it
does not in any way reduce
ground clearance or cornering
clearance, limit suspension travel, steering travel or control operation, or obscure lights or reflectors.
• Accessories 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.
• Bulky 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.
• Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the fre1-4
edom of movement of the operator and may limit control ability, therefore, such accessories are not recommended.
G Use caution when adding electrical accessories. If electrical
accessories exceed the capacity
of the scooter’s electrical system,
an electric 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, braking, and comfort. Other tires,
rims, sizes, and combinations may
not be appropriate. Refer to page
6-11 for tire specifications and more
information on replacing your tires.

Be 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 stopping on a wet surface.
Slow down as you approach a
corner or turn. Once you have
completed 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 pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.
G
G
Always wear a helmet, gloves,
trousers (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. Use a strong
cord to secure any luggage to the
carrier (if equipped). A loose load
will affect the stability of the scooter and could divert your attention from the road. (See page
1-1).

G Railroad crossings, streetcar
rails, iron plates on road construction sites, and manhole
covers become extremely slippery when wet. Therefore, slow
down when approaching such
areas and cross them with caution.
G Keep in mind that braking on a
wet road is much more difficult.
G Ride slowly down a hill, as braking downhill can be very difficult.
Fuel consumption depends largely on
your riding style. Consider the following tips to reduce fuel consumption:
G Avoid high engine speeds during

read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves to the correct operating clearances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating must be avoided.
When parking, stop the engine, and
then remove the key from the main

Checking the spark plug
The spark plug is an important engine
component, which should be checked periodically, preferably by a
Yamaha dealer. Since heat and deposits will cause any spark plug to
slowly erode, it should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally). If the spark plug shows a
distinctly different color, the engine
could be operating improperly. Do not
attempt to diagnose such problems
yourself. Instead, have a Yamaha
dealer check the vehicle.
If the spark plug shows signs of electrode erosion and excessive carbon
or other deposits, it should be replaced.
6-6
Specified spark plug:
NBR8HS/NGK (for CS50 CS50Z)
BPR4HS/NGK (for CS50M)
Before installing a spark plug, the

Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low brake fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
G
G
Refill with the same type of brake
fluid. Mixing fluids may result in a

Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems yourself. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
and know-how to service the scooter
properly.
Use only genuine Yamaha replacement parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.

s WARNING
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoline or gasoline vapors can ignite or
explode, causing severe injury or

EAU26092
Care
ECA15192
NOTICE
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use
before cleaning the vehicle.
Using a brush, harsh chemical products or cleaning compounds
when cleaning these parts will
scratch or damage their surface.
Wax also should not be applied to
any matte colored finished parts.
While the open design of a scooter
reveals the attractiveness of the technology, it also makes it more vulnerable. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go
unnoticed on a car, however, it
detracts from the overall appearance
of a scooter. Frequent and proper
care does not only comply with the
terms of the warranty, but it will also
keep your scooter looking good,
extend its life and optimize its performance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors, including the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such pro7-1
ducts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA10781
NOTICE
G Avoid using strong acidic wheel cleaners, especially on spoked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, thoroughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protection spray.
G Improper cleaning can damage
plastic parts such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc. Use
only a soft, clean cloth or sponge with mild detergent and
water to clean plastic.
G Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive

cleaning products, solvent or thinner, fuel (gasoline), rust removers
or inhibitors, brake fluid, antifreeze
or electrolyte.
G Do not use high-pressure washers or steam-jet cleaners since they cause water seepage
and deterioration in the following areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instruments, switches and lights),
breather hoses and vents.
G For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or scratching. Some cleaning compounds for plastic may leave
scratches on the windshield.
Test the product on a small hidden part of the windshield to
make sure that it does not leave any marks. If the windshield
is scratched, use a quality
plastic polishing compound
after washing.
After normal use
1. Remove dirt with warm water, a
mild detergent, and a soft, clean
sponge, and then rinse thoroughly with clean water. Use a
toothbrush or bottlebrush for
hard-to-reach areas. Stubborn
dirt and insects will come off
more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.
After riding in the rain, near the sea or
on salt-sprayed roads
1. Since sea salt or salt sprayed on
the roads during winter are extremely corrosive in combination
with water, carry out the following
steps after each ride in the rain,
near the sea or on salt-sprayed
roads.
TIP
Salt sprayed on roads in the winter
may remain well into spring.
1. Clean the scooter with cold water
and a mild detergent after the
engine has cooled down. NOTICE: Do not use warm water
7-2
since it increases the corrosive
action of the salt. [ECA10791]
2. Apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, surfaces to prevent corrosion.
After cleaning
1. Dry the scooter with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainlesssteel parts, including the exhaust
system. (Even the thermally induced discoloring of stainless-steel
exhaust systems can be removed
through polishing.)
3. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal, including chrome- and nickel-plated,
surfaces.
4. Use spray oil as a universal cleaner to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely
before storing or covering it.

Contaminants on the brakes or
tires can cause loss of control.
G Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
G Before operating the scooter
test its braking performance
and cornering behavior.

Storage
Short-term
Always store your scooter in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA10820
NOTICE
G Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
G To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemicals are stored.
ECA10800
NOTICE
G Apply spray oil and wax sparingly and make sure to wipe
off any excess.
G Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
G Avoid using abrasive polishing
compounds as they will wear
away the paint.
Long-term
Before storing your scooter for several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Drain the carburetor float chamber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the drained fuel into the fuel tank.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap
onto the spark plug, and then
place the spark plug on the
cylinder head so that the
electrodes are grounded.
(This will limit sparking during
the next step.)
d. Turn the engine over several
times with the starter. (This
will coat the cylinder wall with
oil.) WARNING! To prevent
damage or injury from sparking, make sure to ground
the spark plug electrodes
while turning the engine
over.

7.
8.
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap.
Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alternatively, turn the wheels a little
every month in order to prevent
the tires from becoming degraded in one spot.
Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a
month. Do not store the battery in
an excessively cold or warm place [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
information on storing the battery, see page 6-19.
