Tires
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA10500
WARNING0
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the am-
bient 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 ap-
proved for this model.
EWA11020
WARNING0
Because loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your motorcycle, you
should keep the following precau-
tions in mind.
●NEVER OVERLOAD THE MO-
TORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and acces-
sories does not exceed the
specified maximum load for the
vehicle.
●Do not carry along loosely
packed items, which can shift
during a ride.
●Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.

PERIODIC MAINTENANCE AND MINOR REPAIR
●Adjust the suspension and tire
air pressure with regard to the
load.
●Check the tire condition and air
pressure before each ride.Tire inspection
1. Tire sidewall
2. Tire tread depth
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.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
EWA10470
WARNING0
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the ve-
hicle 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.

WARNING0
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle cannot be guaranteed.
After extensive tests, only the
tires listed below have been
approved for this model by
Yamaha Motor Co., Ltd.
Always make sure that the
valve caps are securely in-
stalled to prevent air pressure
leakage.
Use only the tire valves and
valve cores listed below to
avoid tire deflation during a
ride.

WARNING0
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 advisable before doing any
high-speed riding to ride con-
servatively 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.
EAU21960
Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.
●The wheel rims should be
checked 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
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
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 characteris-
tics.
EAU22041
Adjusting the clutch lever
free play
1. Locknut
2. Adjusting bolt
3. Clutch lever free play
The clutch lever free play should mea-
sure 10.0-15.0 mm (0.39-0.59 in) as
shown. Periodically check the clutch
lever free play and, if necessary, ad-
just it as follows.
1. Loosen the locknut at the clutch
lever.
2. To increase the clutch lever free
play, turn the adjusting bolt in di-
rection (a). To decrease the clutch
lever free play, turn the adjusting
bolt in direction (b).

WARNING0
●Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild de-
tergent.
●Before operating the motorcy-
cle test its braking perfor-
mance and cornering behavior.
ECA10800CAUTION:
●Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess
●Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
●Avoid using abrasive polishing
compounds as they will wear
away the paint.
NOTE:
Consult a Yamaha dealer for advice
on what products to use.
EAUM1900
Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA10810CAUTION:
●Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp, while it is
still wet, will allow water and
humidity to seep in and cause
rust.
●To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
