performance, apply both brake levers
simultaneously.TIP● As the unified brake system is
mechanical, additional free play
can be felt in the front brake lever
when the rear brake lever is be-
ing pulled.
● The unified brake system does
not function when the front brake
is applied alone.

WARNING
Gasoline and gasoline vapors are
extremely ammable. To avoid res
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the en-
gine and be sure that no one is
sitting on the vehicle. Never re-
fuel while smoking, or while in the
vicinity of sparks, open fl ames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfi ll the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank fi ll-
er hole. Stop fi lling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine
or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel im-
mediately.
NOTICE:
Immedi-
ately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel
may deteriorate painted sur-
faces or plastic parts.[ECA10071]
4. Be sure to securely close the fuel
tank cap.

WARNING
Gasoline is poisonous and can
cause injury or death. Handle
gasoline with care. Never siphon
gasoline by mouth. If you should

Recommended fuel:
REGULAR UNLEADED GASOLINE
ONLY
Fuel tank capacity:
8.0 L (2.11 US gal) (1.76 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use of unleaded fuel will extend spark plug
life and reduce maintenance costs.
EAU13433
Catalytic converterThis model is equipped with a cata-
lytic converter in the exhaust system.
EWA10862
WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.● Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.● Make sure that the exhaust
system has cooled down be-
fore doing any maintenance
work.● Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

OPERATION AND IMPORTANT RIDING POINTS
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:● Avoid high engine speeds during
acceleration.● Avoid high engine speeds with no
load on the engine.● 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 cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod in the life of your engine than the
period between 0 and 1000 km (600
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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAUT3540
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for fi ve to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000
km (600 mi) of operation, be sure
to change the engine oil and final
transmission oil, and to clean the
oil strainer.
[ECA16501]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
