Valve clearance
The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.
EAU64412
Tires
Tires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
WARNING
EWA10504
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or d eath from loss of
control.  The tire air pressure must be
checked and a djuste d on col d
tires (i.e., when the temperature
of the tires equals the am bient
temperature).
 The tire air pressure must be
a d juste d in accor dance with the
ri din g speed and with the total
wei ght of ri der, passen ger, car-
g o, an d accessories approve d
for this mo del.

WARNING
EWA10512
Never overloa d your vehicle. Opera-
tion of an overloa ded vehicle coul d
cause an acci dent.
Tire inspection
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 side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
TIP
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
WARNING
EWA10472
 Have a Yamaha dealer replace
excessively worn tires. Besi des
b ein g ille gal, operatin g the vehi-
cle with excessively worn tires

 The replacement of all wheel
and b rake-relate d parts, inclu d-
in g the tires, shoul d b e left to a
Yamaha dealer, who has the
necessary professional knowl-
e dg e an d experience to d o so.
 Ride at mo derate spee ds after
chan gin g a tire since the tire
surface must first b e “broken

6 This model is equipped with tubeless
tires and tire air valves.
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

Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points.
 Check each wheel for cracks, de-
formation and other damage. If
any damage is found, have the
wheel inspected by your Yamaha
dealer. Do not attempt to repair or
straighten a bent or damaged
wheel.
 Check the spokes for looseness. If
any loose spokes are found, have
the wheel adjusted by your
Yamaha dealer. Improperly tight-
ened spokes can cause wheel
misalignment.
 Have the wheel balanced whenev-
er the tire or tube has been re-
placed. An unbalanced wheel can
result in adverse handling charac-
teristics and shortened tire life.
EAU42851
Clutch lever
Since this model is equipped with a hy-
draulic clutch, adjusting the clutch le-
ver free play is not needed. However, it
is necessary to check the hydraulic
system for leakage before each ride. If
the clutch lever free play does become
excessive, and shifting becomes rough
or clutch slippage occurs, causing
poor acceleration, there may be air in
the clutch system. If there is air in the
hydraulic system, have a Yamaha deal-
er bleed the system before operating
the motorcycle.

Checkin g 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
EWA14212
A soft or spon gy feelin g in the b rake
lever can in dicate the presence of
air in the hy draulic system. If there is
air in the hy draulic system, have a
Yamaha dealer blee d the system be-
fore operatin g the vehicle. Air in the
hy draulic system will diminish the
b rakin g performance, which may re-
sult in loss of control and an acci-
d ent.
EAU36505
Brake li ght switches
The brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU36891Front brake pa ds
Each front brake pad is provided with
wear indicators, which allows you to
check the brake pad wear without hav-
ing to disassemble the brake. To check
the brake pad wear, check the position
of the wear indicators while applying
the brake. If a brake pad has worn to
the point that a wear indicator almost
touches the brake disc, have a
Yamaha dealer replace the brake pads as a set.
EAU22501Rear brake pa ds
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.

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
EWA16011
Improper maintenance can result in
loss of b raking a bility. O bserve
these precautions:  Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducing brakin g
performance. 
Clean the filler cap before re-
moving . Use only DOT 4 brake
flui d from a seale d container.
 Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
 Refill with the same type of
brake flui d. A ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
 Be careful that water or dust
d oes not enter the brake flui d
reservoir when refillin g. Water
will si gnificantly lower the boil-
in g point of the flui d an d may re-
sult in vapor lock, an d d ir
t may
clo g the ABS hy draulic unit
valves.
NOTICE
ECA17641
Brake flui d may damag e painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.
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
system 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.

Chan gin g the brake an d

Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake and clutch
master cylinders and calipers as well
as the brake and clutch hoses replaced
at the intervals listed below or whenev-
er they are damaged or leaking.
 Oil seals: Replace every two
years.
 Brake and clutch hoses: Replace
every four years.
EAU23115
Checkin g an d lu bricatin g the
throttle grip an d ca ble
The operation of the throttle grip
should be checked before each ride. In
addition, the cable should be lubricat-
ed by a Yamaha dealer at the intervals
specified in the periodic maintenance
chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from wa-
ter entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
