Periodic maintenance and lubrication chart
NOTE:
The annual checks must be performed every year, except if a kilometer-based maintenance is performed
instead.
From 30000 km, repeat the maintenance intervals starting from 6000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

comes on just before braking takes
effect. If necessary, adjust the brake
light switch as follows.
Turn the adjusting nut while holding
the rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction (a).
To make the brake light come on later,
turn the adjusting nut in direction (b).
EAU22420
Front brake pads
Each front brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear wit-
hout 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 thewear indicator groove has almost
disappeared, have a Yamaha dealer
replace the brake pads as a set.
EAU22480
Rear brake pads
Each rear brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear wit-
hout having to disassemble the brake.
Check the brake pad wear as follows.
1. Remove the brake caliper bolt,
and then tilt the caliper forward to
inspect the wear indicator groo-
ve. If a brake pad has worn to the
point that the wear indicator gro-
ove has almost disappeared,
have a Yamaha dealer replace
the brake pads as a set.2. Install the brake caliper bolt, and
then tighten it to the specified
torque.
EAU22610
Checking the brake fluid
level
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Tightening torque:
Brake caliper bolt:

Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke 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 leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level by
turning the handlebars.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used for the front brake system.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
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.
EAU22720
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 brake
master cylinder and caliper as well as
the brake hose replaced at the inter-
vals listed below or whenever they are
damaged or leaking.
Oil seals: Replace every two
years.
Brake hose: Replace every four
years.Recommended brake fluid:
