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.
WARNING

 Have a Yamaha dealer replace
excessively worn tires. Besi des

 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.

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


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 vehicle
may be different, which coul d

 Always make sure that the valve
caps are securely installed to
prevent air pressure leakag e.
 Use only the tire valves an d

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.
 After repairing or replacing the
front tire, tighten the valve stem
nut and locknut to the specified
torques.

ca blePeriodically check the rear brake lock
cable length and adjust if necessary.
1. Release the rear brake lock lever.
2. To increase the rear brake lock ca- ble length, turn the adjusting nut at
the rear brake caliper in direction
(a). To decrease the rear brake
lock cable length, turn the adjust-
ing nut in direction (b). 3. Confirm that the rear brake lock
lever (page 5-18) functions prop-
erly and that the rear wheel rotates
freely when unlocked.

Checking the rear brake lockThe rear brake lock must be checked
at the intervals specified in the periodic
maintenance and lubrication chart.
1. Adjust the rear brake lock cable.
2. Apply the rear brake lock, and then try to push the vehicle to con-
firm that the rear brake lock func-
tions properly.
3. The rear brake lock caliper is pro- vided with a wear indicator, which
allows you to check the rear brake
lock pads. To check the rear brake
lock pads, check the position of
the indicator when the rear brake
lock lever is applied. If the indica-
tor has passed the wear indicator
groove, have a Yamaha dealer
check the rear brake lock.
4. Make sure that there are no tears or cracks on the rubber boot.

Rear brake The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart. Each brake pad is
provided with a wear indicator, which
allows you to check the brake pad
wear without having to disassemble
the brake. To check the brake pad
wear, check the position of the wear in-
dicator while applying the brake. If a
brake pad has worn to the point that
the wear indicator almost touches the
brake disc, have a Yamaha dealer re-
place 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.TIPMake sure the reservoir is parallel to
the ground when checking.NOTICE
ECA17641
Brake fluid may damag e painted
surfaces or plastic parts. Always
clean up spille d flui d imme diately.Front brake Rear
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 b raking a bility. O bserve
these precautions: 
Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducin g brakin g
performance.
 Clean the filler cap before re-
movin g. 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 d oes not
enter the brake flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the boilin g point of
the flui d an d may result in vapor

Drive beltThe drive belt should be visually in-
spected before each ride. Check for
excessive wear, damage, and dirt. Al-
so, the drive belt tension must be
checked and adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance chart.
To check the drive belt
1. On a level surface, place the vehi- cle on its centerstand.
2. Rotate the rear wheel and check the belt surface for signs of wear
or damage. 3. If cracks, excessive wear, or dam-
age is found, have the belt in-
spected or replaced by your
Yamaha dealer.
4. If the drive belt or drive belt sprocket is dirty, remove the drive
belt covers by removing the bolts
and quick fasteners.
5. Clean the drive belt and remove any debris from the drive belt
sprocket. NOTICE: Do not allow
d irt or san d to accumulate in the
d rive belt area, otherwise the

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! Dama ge to the
outer housin g of cab les may result
in internal rustin g an d cause inter-

Checkin
g an d lu bricatin g the
throttle grip an d ca bleThe 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.
