Checking the front and rear
brake padsThe front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart. Each brake pad
is provided with a wear indicator
groove, which allows you to check
the brake pad wear without having to
disassemble the brake. To check the
brake pad wear, check the wear indi-
cator grooves.

Observe these precautions:
8When checking the fluid level,
make sure that the top of the
master cylinder or brake fluid
reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.1.Minimum level markREARRecommended brake fluid:
DOT 4
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the master cylinder or
brake fluid reservoir when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.

EAU03607
Checking the brake fluid
levelInsufficient 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
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake level is low, be
sure to check the brake pads for
wear and the brake system for leak-
age.1.Minimum level mark FRONT

2.Remove the blown fuse, and
then install a new fuse of the
specified amperage.

cCDo not use a fuse of a higher
amperage rating than recommend-
ed to avoid causing extensive
damage to the electrical system
and possibly a fire.3.Turn the key to ÒONÓ and turn on
the electrical circuit in question to
check if the device operates.

9 Engine overheating
EW000070
w8Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
8After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the
hissing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the
cap.Wait until the 
engine has cooled.
Check the coolant level in the 
reservoir and radiator.
The coolant level 
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again, 
have a 
Yamaha dealer check 
and repair the cooling system.
There is
leakage.
There is 
no leakage.
NOTE:
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
