Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long
distances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dama-
ging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cros-
sings).
EAU16841
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1600 km
(1000 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clea-
rances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU17101
0–1000 km (0–600 mi)
Avoid prolonged operation above
4500 r/min. NOTICE: After 1000
km (600 mi) of operation, the
engine oil must be changed,
and the oil filter element repla-
ced.
[ECA11151]
1000–1600 km (600–1000 mi)

Engine oil and oil filter
element
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed and the oil filter
element replaced at the intervals spe-
cified in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
Make sure that the vehicle is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
2. Start the engine, warm it up for
10–15 minutes, and then turn it
off.
3. Remove the oil filler cap, wipe the
dipstick clean, insert it back into
the oil filler hole (without scre-
wing it in), and then remove it
again to check the oil level.
TIP
The engine oil tank is located
inside of the frame.
The engine oil should be between
the minimum and maximum level
marks.
1. Engine oil filler cap
2. Maximum level mark
3. Minimum level mark
EWA10361
Never remove the engine oil tank
cap after high-speed operation,
otherwise hot engine oil could
spout out and cause damage or
injury. Always let the engine oil cool
down sufficiently before removing
the oil tank cap.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se it to the correct level. NOTICE:
Do not operate the vehicle until
you know that the engine oil
level is sufficient.
[ECA10011]
5. Install the oil filler cap.
To change the engine oil (with or
without oil filter element
replacement)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Remove the engine guard by
removing the screws.

Rear brake (for XT660ZA)
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
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 fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
TIP
For XT660ZA, the rear brake fluid
reservoir is located under the seat.
(See page 3-16).
Observe these precautions:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing 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 performan-
ce.
Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water will
significantly lower the boiling
point of the fluid and may result
in vapor lock, and dirt may clog
the ABS hydraulic unit valves.
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.
EAU22731
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders 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.
Recommended brake fluid:
