4-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.

Hydraulic brake and clutch systems
• After disassembling the master cylinder, caliper cylinder or clutch release cylinder, always replace the brake fluid.
Check the brake fluid level of the master cylinder and clutch release cylinder regularly and fill as required.
• Replace the oil seals on the inner parts of the master cylinder, caliper cylinder and clutch release cylinder every two
years.
• Replace the brake and clutch hoses every four years or if cracked or damaged.

Inspecting the brake fluid
levelInsufficient brake fluid may let air enter
the brake or clutch system, possibly
causing them to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and fill
when necessary. Low brake fluid levels
may indicate worn brake pads and/or
brake system leakage. If the brake lev-
el is low, be sure to inspect the brake
pads for wear or brake system for leak-
age.Observe these precautions:
l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake or clutch
performance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake or clutch perfor-
mance.

l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.
EAU00742
Brake fluid replacementThe brake fluid should be replaced only
by trained Yamaha service personnel.
Have the Yamaha dealer replace the
following components during periodic
maintenance or when they are dam-
aged or leaking:l
oil seals (every two years)
l
brake hoses (every four years)
