Tires
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10501
Operation of this vehicle with
improper tire pressure may cause
severe injury or death from loss of
control.
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-
re 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,
cargo, and accessories appro-
ved for this model.

EWA10470
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
vehicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, inclu-
ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
EAU21960
Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
●The wheel rims should be chec-
ked 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 crac-
ked 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 characte-
ristics.

Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
●Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
●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.
●Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
●As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if
the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
●Oil seals: Replace every two
years.
●Brake hoses: Replace every four
years.

ked before each ride and adjusted if
necessary.
EAU22783
To check the drive chain slack
1. Drive chain slack
1. Place the motorcycle on the
sidestand.
TIP
When checking and adjusting the dri-
ve chain slack, there should be no
weight on the motorcycle.
2. Shift the transmission into the
neutral position.3. Move the rear wheel by pushing
the motorcycle to locate the tigh-
test portion of the drive chain,
and then measure the drive chain
slack as shown.
4. If the drive chain slack is inco-
rrect, adjust it as follows.
TIP
When checking the drive chain slack,
the chain tensioner should not be tou-
ching the drive chain.
EAU22921
To adjust the drive chain slack
1. Remove the cotter pin from the
axle nut, and then loosen the axle
nut.
2. Loosen the chain puller locknut
at each end of the swingarm.
3. To tighten the drive chain, turn
the drive chain slack adjusting
bolt on each end side of the
swingarm in direction (a). To loo-
sen the drive chain, turn the
adjusting bolt on each side of theswingarm in direction (b), and
then push the rear wheel forward.
NOTICE: Improper drive chain
slack will overload the engine
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 wit-
hin 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.
