6. Refill with the specified amount
of the recommended final trans-
mission oil, and then install and
tighten the oil filler cap. WAR-
NING! Make sure that no
foreign material enters the final
transmission case. Make sure
that no oil gets on the tire or
wheel.
[EWA11311]
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.

Coolant (CS50Z)
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2102
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant level check window
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5).
4. Open the reservoir cap, and then
add coolant to the maximum
level mark. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.

water or soft tap water instead.
Do not use hard water or salt
water since it is harmful to the
engine. If water has been used
instead of coolant, replace it
with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected
against frost and corrosion. If
water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.

Tires
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10501
sWARNING
Operation of this vehicle with
improper tire pressure may cause
severe injury or death from loss of
control.
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-re of the tires equals the
ambient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories appro-
ved for this model.
EWA10511
sWARNING
Never overload your vehicle. Ope-
ration of an overloaded vehicle
could cause an accident.
Tire inspection
1. Tire wear indicator
2. Tire sidewall
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or if
the sidewall is cracked, have a Yama-
ha dealer replace the tire immediately.

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.

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.

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.

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

listed below or whenever they are
damaged or leaking.
●Oil seals: Replace every two
years.
●Brake hose: Replace every four
years.
