TIP Air filter
• This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with com- pressed air to avoid damaging it.
• The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
 Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

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 b rake
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 and an acci-
d ent.
EAU36504
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.

Checkin g the front an d rear
b rake pa dsThe front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22432
Front brake pad s
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the wear indicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU22501
Rear
brake pa ds
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.
EAU40262
Checkin g the brake flui d levelBefore riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.

WARNING
EWA16011
Improper maintenance can result in
loss of brakin g a bility. O bserve
these precautions:  Insufficient brake flui d may al-
low air to enter the b rake sys-
tem, re ducin g brakin g
performance.
 Clean the filler cap before re-
moving . Use only DOT 4 b rake
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 or dust
d oes not enter the brake flui d
reservoir when refillin g. Water
will si gnificantly lower the boil-
in g point of the flui d an d may re-
sult in vapor lock, an d d ir
t may

valves.
NOTICE
ECA17641
Brake flui d may damag e painted
surfaces or plastic parts. Always
clean up spille d flui d imme diately.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 and/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 riding.

Chan gin g the brake flui dHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the master cylinders 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.

Drive belt slackThe drive belt slack should be checked
and adjusted at the intervals specified
in the periodic maintenance and lubri-
cation chart.
EAU55773
To check the drive belt slack
1. Place the vehicle on the side- stand.
2. Note the current position of the drive belt using the marks near the
drive belt check hole.
3. Note the position of the drive belt with a force of 45 N (4.5 kgf, 10 lbf)
applied to the belt with a belt ten-
sion gauge as shown.
TIPA belt tension gauge is available at a
Yamaha dealer.4. Calculate the drive belt slack bysubtracting the measurement not-
ed in step 2 from the measure-
ment noted in step 3.
5. If the drive belt slack is incorrect, have a Yamaha dealer adjust it.
