coolant reservoir cap guard and the cap, add coolant to the maxi-
mum level mark, and then install
the cap and the cap guard.
19. Start the engine, and then check the vehicle for coolant leakage. If

TiresTires 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 death 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.TIPThe tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.

Have a Yamaha d ealer replace
excessively worn tires. Besid es

The replacement of all wheel
and b rake-relate d parts, inclu d-

Yamaha dealer, who has the
necessary professional knowl-

Tire information
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
EWA10902
The front an d rear tires shoul d
b e of the same make an d d e-
si gn, otherwise the han dlin g characteristics of the motorcy-
cle may b

coul d lea d to an acci dent.
Always make sure that the valve
caps are securely installe d to
prevent air pressure leaka ge.
Use only the tire valves an d

WARNING
EWA10601
This motorcycle is fitte d with super-
hi gh-spee d tires. Note the following
points in or der to make the most ef-
ficient use of these tires. Use only the specifie d replace-
ment tires. Other tires may run
the dan ger of bursting at super
hi gh spee ds.
Bran d-new tires can have a rel-
atively poor g rip on certain road
surfaces until they have been
“ b roken in”. Therefore, it is a d-
visa ble before doin g any hi gh-
speed ridin g to ri de conserva-
tively for approximately 100 km
(60 mi) after installin g a new tire.
The tires must b e warmed up

EAU21963
Cast wheelsTo 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, warp-
age or other 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 de-
formed 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.
EAU42851
Clutch leverSince 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
playThere 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 brake
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 an d an acci-
d ent.

Brake li ght switchesThe brake light, which is activated by
the brake pedal and brake lever,
should come on just before braking
takes effect. If necessary, have a
Yamaha dealer adjust the brake light
switches.

checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43063
Front brake pa ds
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with
one or two wear indicator grooves,
which allow you to check the brake
pad wear without having to disassem-
ble the brake. To check the brake pad
wear, check the wear indicator
grooves. If a brake pad has worn to the point that a wear indicator groove al-
most appears, have a Yamaha dealer
replace the brake pads as a set.
EAU22471
Rear
brake pad s
Each rear brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.

Checkin g the brake flui d levelBefore riding, check that the brake fluid
is above the minimum level mark.
