6Tire information
This motorcycle is equipped with tube
tires.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10461
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which
could lead to an accident.After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10562
●
It is dangerous to ride with a
worn-out tire. When a tire tread
begins to show crosswise lines,
have a Yamaha dealer replace
the tire immediately.
●
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.
●
It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tubevery carefully and replace it as
soon as possible with a high-
quality product.
●
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.

Cast wheels
WARNING
EWA10610
The wheels on this model are not de-
signed for use with tubeless tires.
Do not attempt to use tubeless tires
on this model.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, warpage or oth-
er damage 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 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.
EAU37913
Checking the brake lever free
play There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14211
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish thebraking performance, which may re-
sult in loss of control and an acci-
dent.1. No brake lever free play

Adjusting the brake pedal free
play The brake pedal free play should mea-
sure 20.0–30.0 mm (0.79–1.18 in) at
the brake pedal end as shown. Period-
ically check the brake pedal free play
and, if necessary, adjust it as follows.
To increase the brake pedal free play,
turn the brake pedal free play adjusting
nut at the brake rod in direction (a). To
decrease the brake pedal free play,
turn the adjusting nut in direction (b).
WARNING
EWA10680
●
After adjusting the drive chain
slack or removing and installing
the rear wheel, always check the
brake pedal free play.
●
If proper adjustment cannot be
obtained as described, have a
Yamaha dealer make this ad-
justment.
●
After adjusting the brake pedal
free play, check the operation of
the brake light.

Checking the shift pedal The operation of the shift pedal should
be checked before each ride. If opera-
tion is not smooth, have a Yamaha
dealer check the vehicle.

Brake light switches The brake light, which is activated by
the brake pedal and brake lever, should
come on just before braking takes ef-
fect. If necessary, adjust the rear brake
light switch as follows, but the front
brake light switch should be adjusted
by a Yamaha dealer.
1. Remove panel A. (See page 6-7.)
2. Turn the rear brake light switch ad-
justing nut while holding the rear
brake light switch in place. To
make the brake light come on ear-
lier, turn the adjusting nut in direc-tion (a). To make the brake light
come on later, turn the adjusting
nut in direction (b).
3. Install the panel.

Checking the front brake pads
and rear brake shoes The front brake pads and the rear brake
shoes must be checked for wear at the
intervals specified in the periodic main-
tenance and lubrication chart.

Front brake pads
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake

the brake pads as a set.
EAU22540
Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble 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 reaches
the wear limit line, have a Yamaha
dealer replace the brake shoes as a
set.
EAU37002
Checking the brake fluid level Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.
WARNING
EWA15980
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
●
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
●
Clean the filler cap before re-
moving. Use only DOT 3 or DOT
4 brake fluid from a sealed con-
tainer.
●
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
●
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 3 or DOT 4 may
result in a harmful chemical re-
action.
●
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up spilled fluid immediately.

6 As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.
EAU22722
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion 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.

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.

1. Place the motorcycle on the cen-
terstand.
2. Shift the transmission into the neu-
tral position.
3. Remove the drive chain slack

adjust it as follows.
EAU55190
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack.
1. Place the motorcycle on the cen-
terstand.
2. Loosen the brake pedal free play
adjusting nut and the brake torque
rod nut.3. Loosen the axle nut, then loosen
the locknut at each end of the
swingarm.4. To tighten the drive chain, turn the
drive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en-
gine as well as other vital parts
of the motorcycle and can lead
to chain slippage or breakage.
To prevent this from occurring,
keep the drive chain slack with-
in the specified limits.

Cleaning and lubricating the
drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.NOTICE
ECA10583
The drive chain must be lubricated
after washing the motorcycle, riding
in the rain or riding in wet areas.1. Remove all dirt and mud from the
drive chain with a brush or cloth.TIPFor a thorough cleaning, have a
Yamaha dealer remove the drive chain
and soak it in solvent.2. Spray Yamaha Chain and Cable
Lube or a high-quality spray-type
drive chain lubricant on the entire
chain, making sure that all side
plates and rollers have been suffi-
ciently oiled.
