Periodic maintenance and lubrication chart
NOTE:
●The annual checks must be performed every year, except if a kilometer-based maintenance is performed in-
stead.
●From 50000 km, repeat the maintenance intervals starting from 10000 km.
●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and tech-
nical skills.

NOTE:
If the specified clutch lever free play
could be obtained as described
above, tighten the locknut and skip the
rest of the procedure, otherwise pro-
ceed as follows.
3. Fully turn the adjusting bolt at the
clutch lever in direction (a) to
loosen the clutch cable.
4. Loosen the locknut at the
crankcase.
1. Locknut
2. Clutch lever free play adjusting nut
(crankcase)
5. To increase the clutch lever free
play, turn the adjusting nut in di-
rection (a). To decrease the clutch
lever free play, turn the adjusting
nut in direction (b).
6. Tighten the locknut at the clutch
lever and the crankcase.

Front brake pads
1. Front brake pad wear indicator groove
Each front 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 has almost dis-
appeared, have a Yamaha dealer re-
place the brake pads as a set.
EAU22500
Rear brake pads
1. Rear brake pad lining thickness
Check each rear brake pad for dam-
age and measure the lining thickness.
If a brake pad is damaged or if the lin-
ing thickness is less than 1.0 mm
(0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
EAU22580

PERIODIC MAINTENANCE AND MINOR REPAIR
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake flu-
id is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system leak-
age. If the brake fluid level is low, be
sure to check the brake pads for wear
and the brake system for leakage.
Observe these precautions:
●When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
●Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.
●Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
●Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
●Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid imme-
diately.
●As 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.

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the master
cylinders and calipers as well as the
brake hoses replaced at the intervals
listed below or whenever they are
damaged or leaking.
●Oil seals: Replace every two
years.
●Brake hoses: Replace every four
years.
