SAFETY INFORMATION
EAU10281
MOTORCYCLES ARE SINGLE TRACK
VEHICLES. THEIR SAFE USE AND
OPERATION ARE DEPENDENT UPON
THE USE OF PROPER RIDING
TECHNIQUES AS WELL AS THE
EXPERTISE OF THE OPERATOR.
EVERY OPERATOR SHOULD KNOW
THE FOLLOWING REQUIREMENTS
BEFORE RIDING THIS MOTORCYCLE.
HE OR SHE SHOULD:l
OBTAIN THOROUGH
INSTRUCTIONS FROM A
COMPETENT SOURCE ON ALL
ASPECTS OF MOTORCYCLE
OPERATION.
l
OBSERVE THE WARNINGS AND
MAINTENANCE
REQUIREMENTS IN THE
OWNER’S MANUAL.
l
OBTAIN QUALIFIED TRAINING IN
SAFE AND PROPER RIDING
TECHNIQUES.
l
OBTAIN PROFESSIONAL
TECHNICAL SERVICE AS
INDICATED BY THE OWNER’S
MANUAL AND/OR WHEN MADE
NECESSARY BY MECHANICAL
CONDITIONS.Safe riding
l
Always make pre-operation checks.
Careful checks may help prevent
an accident.
l
This motorcycle is designed to
carry the operator and a passenger.
l
The failure of motorists to detect
and recognize motorcycles in traffic
is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did not
see the motorcycle. Making
yourself conspicuous appears to be
very effective in reducing the
chance of this type of accident.
Therefore:lWear a brightly colored jacket.lUse extra caution when you are
approaching and passing through
intersections, since intersections
are the most likely places for
motorcycle accidents to occur.lRide where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
l
Many accidents involve
inexperienced operators. In fact, many operators who have been
involved in accidents do not even
have a current motorcycle license.
lMake sure that you are qualified
and that you only lend your
motorcycle to other qualified
operators.lKnow your skills and limits.
Staying within your limits may
help you to avoid an accident.lWe recommend that you
practice riding your motorcycle
where there is no traffic until you
have become thoroughly familiar
with the motorcycle and all of its
controls.
l
Many accidents have been caused
by error of the motorcycle operator.
A typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).lAlways obey the speed limit and
never travel faster than warranted
by road and traffic conditions.lAlways signal before turning or
changing lanes. Make sure that
other motorists can see you.

Immediately wipe off spilled fuel with
a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
EAU33500
Recommended fuel:REGULAR UNLEADED GASOLINE ONLY
Fuel tank capacity: 19.2 L (5.07 US gal) (4.22 Imp. gal)
Fuel reserve amount (when the fuel level warning light comes on):
4.5 L (1.19 US gal) (1.00 Imp. gal)
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts, such
as the valves and piston rings, as well
as to the exhaust system.Your Yamaha engine has been designed
to use regular unleaded gasoline with a
research octane number of 91 or higher.
If knocking (or pinging) occurs, use a gasoline of a different brand. Use of
unleaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13431
Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
EWA10860
The exhaust system is hot after
operation. Make sure that the exhaust
system has cooled down before

lubrication will keep your vehicle in the
safest and most efficient condition
possible. The most important points of
inspection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING ON
THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE
MAINTENANCE INTERVALS MAY
NEED TO BE SHORTENED.
