Periodic maintenance and lubrication chart
NOTE:_

The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.


From 50,000 km, repeat the maintenance intervals starting from 10,000 km.


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart. Each brake pad is
provided with wear indicator grooves,
which allow you to check the brake pad
wear without having to disassemble the
brake. If a brake pad has worn to the
point that the wear indicator grooves
have almost disappeared, have a
Yamaha dealer replace the brake pads
as a set.1. Brake pad wear indicator groove (× 3)Front

Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id 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 sys-
tem 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 quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.


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
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 sud-
denly, have a Yamaha dealer
check the cause.

into the wheel hub so that the pro-
jections mesh with the slots.2. Lift the wheel up between the fork
legs.
NOTE:_ Make sure that the slot in the speedom-
eter gear unit fits over the retainer on
the fork leg. _3. Insert the wheel axle.
4. Install the brake calipers by install-
ing the bolts.NOTE:_ Make sure that there is enough space
between the brake pads before install-
ing the brake calipers onto the brake
discs. _
5. Install the brake hose holders by
installing the bolts.
6. Take the motorcycle off the cen-
terstand so that the front wheel is
on the ground.
7. Tighten the wheel axle, then the
front wheel axle pinch bolt and the
brake caliper bolts to the specified
torques.

the brake caliper bracket by in-
stalling the bolt and the nut.
5. Install the axle nut, and then slight-
ly tighten it.
6. Take the motorcycle off the cen-
terstand so that the rear wheel is
on the ground.
