sWARNING
●Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
●Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
●Keep in mind that braking on a
wet road is much more difficult.
●Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.Front

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Avoid high engine speeds during
acceleration.
●Avoid high engine speeds with no
load on the engine.
●Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).

Periodic maintenance and lubrication chart
TIP
●The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
●From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

TIP
●The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
●Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

TIP
The tire tread depth limits may differ
from country to country. Always
comply with the local regulations.
Tire information
This model is equipped with tubeless
tires.
After extensive tests, only the tires lis-
ted below have been approved for
this model by Yamaha Motor España,
S.A.
EWA10470
sWARNING
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
EAU21960
Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
●The wheel rims should be chec-
ked for cracks, bends or warpage
before each ride. If any damage
is found, have a Yamaha dealer
replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or crac-
ked 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
handling characteristics, and a
shortened 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 characte-
ristics.

Checking the front brake
lever free play
1. Front brake lever free play
The brake lever free play should mea-
sure 2.0–5.0 mm (0.08–0.20 in) as
shown. Periodically check the brake
lever free play and, if necessary, have
a Yamaha dealer check the brake sys-
tem.
EWA10641
sWARNING
An incorrect brake lever free play
indicates a hazardous condition in
the brake system. Do not operate
the vehicle until the brake system
has been checked or repaired by a
Yamaha dealer.

Adjusting the rear brake
lever free play
1. Rear brake lever free play
The brake lever free play should mea-
sure 5.0-10.0 mm (0.20-0.40 in) as
shown. Periodically check the brake
lever 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 decrea-
se the brake lever free play, turn the
adjusting nut in direction (b).

Checking the front brake
pads and rear brake shoes
The front brake pads and the rear bra-
ke shoes must be checked for wear at
the intervals specified in the periodic
maintenance and lubrication chart.
EAUS1510
Front brake pads
1. Brake pad checking cover
1. Lining thickness
Check each front brake pad for
damage and measure the lining thick-
ness. If a brake pad is damaged or if
the lining thickness is less than
3.1 mm (0.12 in), have a Yamaha dea-
ler replace the brake pads as a set.
EAU22540
Rear brake shoes
1. Wear indicator 2. Wear limit line
The rear brake is provided with a wear
indicator, which allows you to check
the brake shoe wear without having to
disassemble the brake. To check the
brake shoe wear, check the position
of the wear indicator while applying
the brake. If a brake shoe has worn to
the point that the wear indicator rea-
ches the wear limit line, have a Yama-
ha dealer replace the brake shoes as
a set.

Checking the brake fluid
level
1. Minimum level mark
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 bra-
ke 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.Observe these precautions:
●When checking the fluid level,
make sure that the top of the
master cylinder is level by turning
the handlebars.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the brake master
cylinder and caliper as well as the
brake hose replaced at the intervals
listed below or whenever they are
damaged or leaking.
●Oil seals: Replace every two
years.
●Brake hose: Replace every four
years.

Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated at the intervals specified in the
periodic maintenance chart.
