FOR YOUR SAFETY – PRE-OPERATION CHECKS
EBU31582Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in the Own-
er’s Manual.
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. Before using this vehicle, check the following points:
ITEM ROUTINE PAGE
Brakes • Check operation, free play, fluid level, and fluid leakage.
• Fill with DOT 4 brake fluid if necessary. 5-3, 8-38, 8-42
Parking brake • Check for proper operation. 8-42
Fuel • Check fuel level.
• Fill with the recommended fuel if necessary. 5-3
Engine oil • Check oil level.
• Fill with oil to proper level if necessary. 5-5, 8-14

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
8-41.)
 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 8-39.) 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 8-38.)
EBU33200FuelMake sure there is suffi
cient fuel in the tank.
Specified brake fluid: DOT 4

dy or muddy areas, or at full throttle.
 Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and calipers,
and change the brake fluid.18 *Drive shaft uni-

EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble 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 indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-45, 8-46 for wheel
removal and installation procedures.)
EBU32501Checking the brake fluid levelBefore starting off, 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.1. Brake pad wear indicator groove

WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:
Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance. 
Clean the filler cap 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.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Wa-
ter will significantly lower the boiling
point of the fluid and may result in vapor
lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.

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 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 and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during pe riodic maintenance or
when they are damaged or leaking.
 Replace the oil seals every two years.
 Replace the brake hoses every four years.
EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.1. Brake pedal
