FOR YOUR SAFETY – PRE-OPERATION CHECKS
EBU31584Before starting off, inspect the vehicle to make sure it is in safe operating condition. Use the fol-
lowing checklist and related information as a guide. Also, follow the service intervals in the peri-
odic maintenance chart to keep the vehicle in safe operating condition.
WARNING
EWB00482Failure to inspect or maintain the vehicle properly increases the possibility of an accident
or equipment damage. Do not operate the vehicle if you find any problem. If a problem can-
not be corrected by the procedures provided in this manual, have the vehicle inspected by
a Yamaha dealer. Pre-operation checklist

EBU31731Front and rear brakesBrake pedal
Check that there is no free play in the brake
pedal. If there is free play, have a Yamaha
dealer check the brake system. (See page
8-49.)
Check the operation of the brake pedal. It
should move smoothly and there should be
a firm feeling when the brakes are applied.
If not, have the vehicle inspected by a
Yamaha dealer.
Brake fluid level
Check the brake fluid level. Add fluid if neces-
sary. (See page 8-46.) Brake fluid leakage
Check to see if any brake fluid is leaking out
of the pipe joints or the brake fluid reservoir.
Apply the brakes firmly for one minute. If there
is any leakage, have the vehicle inspected by
a Yamaha dealer.
Brake operation
Check the operation of the brakes at the start
of every drive. Test the brakes at slow speed
after starting out to make sure they are work-
ing properly. If the brakes do not provide
proper braking performance, inspect the
brake system. (See page 8-45.)
EBU33201FuelMake sure there is suffi
cient fuel in the tank.
Specified brake fluid: DOT 4

EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.
EBU36610Checking the brake and YCC-S clutch
fluid levelsBefore starting off, check that the brake and
YCC-S clutch fluids are above the minimum
level marks. Replenish the brake and YCC-S
clutch fluids if necessary.

TIPThe brake and YCC-S clutch fluid reser-
voirs are located under the hood (page
8-11).
For an accurate reading, make sure the ve-
hicle is parked on a level surface.
WARNING
EWB04160Improper maintenance can result in loss of
braking ability or YCC-S clutch operation.
Observe these precautions:
Insufficient brake or YCC-S clutch fluid
may allow air to enter the brake or
YCC-S clutch system, reducing braking
or YCC-S clutch performance.
Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
