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 adjusted on cold
tires (i.e., when the temperature
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, car-
go, and accessories approved
for this model.
WARNING
EWA10512
Never overload your vehicle. Opera-
tion of an overloaded vehicle could
cause an accident.
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.
Cold tire air pressure:
1 person:Front:250 kPa (2.50 kgf/cm², 36 psi)
Rear: 290 kPa (2.90 kgf/cm², 42 psi)
2 persons:
Front:250 kPa (2.50 kgf/cm², 36 psi)
Rear:
290 kPa (2.90 kgf/cm², 42 psi)
Maximum load: Vehicle:
185 kg (408 lb)
The vehicle’s maximum load is the
combined weight of the rider, pas-
senger, cargo, and any accessories.

WARNING
EWA10472
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.
 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 to do so.
 Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.
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 and rear tires should
be of the same make and de-
sign, otherwise the handling characteristics of the motorcy-
cle may be different, which
could lead to an accident.
 Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
 Use only the tire valves and
valve cores listed below to
avoid tire deflation during a ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.

2. Tire air valve core
3. Tire air valve cap with seal

WARNING
EWA10601
This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient use of these tires. Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds. 
Brand-new tires can have a rel-
atively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any high-
speed riding to ride conserva-
tively for approximately 100 km
(60 mi) after installing a new tire.
 The tires must be warmed up
before a high-speed run.
 Always adjust the tire air pres-
sure according to the operating
conditions.
EAU66460
Cast magnesium wheelsTo maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding these wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or 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 the tire or wheel has
been changed or replaced. An un-
balanced wheel can result in poor
performance, adverse handling
characteristics, and shortened tire
life.
These wheels are made of magnesium
and require special care.  When balancing the wheel, use
press-on type weights to avoid
scratching the wheel.

Checking 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 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 the braking performance, which may re-
sult in loss of control and an acci-
dent.

Checking the brake fluid levelBefore riding, check that the brake fluid
is above the minimum level mark.TIPMake sure the reservoir is parallel to
the ground when checking.NOTICE
ECA17641
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.Front brakeRear brake
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 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 rid-
ing.
WARNING
EWA15991
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 4 brake
fluid from a sealed container.
 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 4 may result in a
harmful chemical reaction.
 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.

Cleaning and lubricating the
drive chainThe 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
ECA10584
The drive chain must be lubricated
after washing the motorcycle, riding
in the rain or riding in wet areas.1. Clean the drive chain with a drivechain cleaner and a small soft
brush. NOTICE: To prevent dam-
aging the O-rings, do not clean
the drive chain with steam
cleaners, high-pressure wash-
ers or inappropriate solvents.
[ECA11122]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use
engine oil or any other lubri- cants for the drive chain, as they
may contain substances that
could damage the O-rings.
[ECA11112]
EAU23098
Checking and lubricating the
cablesThe operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubri-
cated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it.
WARNING! Damage to the
outer housing of cables may result
in internal rusting and cause inter-
ference with cable movement. Re-
place damaged cables as soon as
possible to prevent unsafe condi-
tions.
[EWA10712]
Recommended lubricant: Yamaha cable lubricant or other
suitable cable lubricant

If the sidestand does not move up
and down smoothly, have a Yamaha
dealer check or repair it. Otherwise,
the sidestand could contact the
ground and distract the operator, re-
sulting in a possible loss of control.

Checking the front forkThe condition and operation of the
front fork must be checked as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation1. Place the vehicle on a level surfa- ce and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10752]
2. While applying the front brake, push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.
NOTICE
ECA10591
If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it.
