TIP
Air filter
This model’s air filter uses a disposable oil-coated paper element. This el ement cannot be cleaned with compressed
air, doing so will only damage it.
The air filter element needs to be replaced more fr equently when riding in unusually wet or dusty areas.
Hydraulic brake service
Regularly check the front and rear brake fluid levels. Replenish if necessary.
Every two years replace the rear brake master cylinder, the internal components of the front brake master cylinder, the brake calipers, and change the brake fluid.
Replace the brake hoses every four years or sooner if cracked, damaged, or if any section of the stainless steel brakehose has turned black.

12 The tires should 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 Yamaha
dealer replace the tire immediately.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations.
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 optimalcharacteristics.
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 should be checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10482
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 ahigh-speed ride.
After extensive tests, only the tires list-
ed below are approved for this model
by Yamaha.
Minimum tire tread depth (front and
rear): 1.6 mm (0.06 in)

2. Tire air valve core

Checking the brak
e 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.

Brake light switchesThe brake light should come on just be-
fore braking takes effect. The brake
light is activated by switches connected
to the brake lever and brake pedal.
Since the brake light switches are com-
ponents of the anti-lock brake system,
they should only be serviced by a
Yamaha dealer.
EAU22393
Checking the front and rear
brake padsThe front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU36891
Front brake pads
Each front brake pad is provided with
wear indicators, which allows you to
check the brake pad wear without hav-
ing to disassemble the brake. To check
the brake pad wear, check the position
of the wear indicators while applying
the brake. If a brake pad has worn to
the point that a wear indicator almost touches the brake disc, have a Yamaha
dealer replace the brake pads as a set.
EAU48071
Rear brake pads
Each rear brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wear
indicator groove almost appears, have
a Yamaha dealer replace the brake
pads as a set.

Checking the br ake fluid levelBefore riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the res-
ervoir in an upright position. Replenish
the brake fluid if necessary.NOTICE
ECA17641
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
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 indicate
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 vaporlock.
