SAFETY INFORMATION

EAU10270

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:

● OBTAIN THOROUGH INSTRUC-

TIONS FROM A COMPETENT
SOURCE ON ALL ASPECTS OF
MOTORCYCLE OPERATION.

● OBSERVE THE WARNINGS

AND MAINTENANCE REQUIRE­MENTS IN THE OWNER’S MAN­UAL.

● OBTAIN QUALIFIED TRAINING

IN SAFE AND PROPER RIDING
TECHNIQUES.

● OBTAIN PROFESSIONAL TECH-

NICAL SERVICE AS INDICATED
BY THE OWNER’S MANUAL

AND/OR WHEN MADE NECES­SARY BY MECHANICAL CONDI­TIONS.

Safe riding

● Always make pre-operation

checks. Careful checks may help
prevent an accident.

● This motorcycle is designed to

carry the operator and a passen­ger.

● 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:

• Wear a brightly colored jacket.

• Use extra caution when you are

approaching and passing
through intersections, since in-

tersections are the most likely
places for motorcycle accidents
to occur.

• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.

● Many accidents involve inexperi-

enced operators. In fact, many op­erators who have been involved in
accidents do not even have a cur­rent motorcycle license.

• Make sure that you are qualified
and that you only lend your
motorcycle to other qualified op­erators.

• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.

• We 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.

● Many accidents have been

caused by error of the motorcycle
operator. A typical error made by
the operator is veering wide on a

1

1-1

SAFETY INFORMATION

turn due to EXCESSIVE SPEED
or undercornering (insufficient lean
angle for the speed).

1

• Always obey the speed limit and
never travel faster than warrant­ed by road and traffic conditions.

• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.

● The posture of the operator and

passenger is important for proper
control.

• The operator should keep both
hands on the handlebar and
both feet on the operator foot­rests during operation to main­tain control of the motorcycle.

• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger footrests.

• Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.

● Never ride under the influence of

alcohol or other drugs.

● This motorcycle is designed for on-

road use only. It is not suitable for
off-road use.

Protective apparel

The majority of fatalities from motor­cycle accidents are the result of head
injuries. The use of a safety helmet is
the single most critical factor in the pre­vention or reduction of head injuries.

● Always wear an approved helmet.

● Wear a face shield or goggles.

Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.

● The use of a jacket, heavy boots,

trousers, gloves, etc., is effective in
preventing or reducing abrasions
or lacerations.

● Never wear loose-fitting clothes,

otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.

● Never touch the engine or exhaust

system during or after operation.
They become very hot and can

cause burns. Always wear protec­tive clothing that covers your legs,
ankles, and feet.

● A passenger should also observe

the above precautions.

Modifications

Modifications made to this motorcycle
not approved by Yamaha, or the re­moval of original equipment, may ren­der the motorcycle unsafe for use and
may cause severe personal injury.
Modifications may also make your
motorcycle illegal to use.

Loading and accessories

Adding accessories or cargo to your
motorcycle can adversely affect stabili­ty and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use ex­treme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
Here are some general guidelines to
follow if loading cargo or adding acces­sories to your motorcycle:

1-2

SAFETY INFORMATION

Loading
The total weight of the operator, pas­senger, accessories and cargo must
not exceed the maximum load limit of
215 kg (474 lb) (CAL)(ZAF) / 216 kg
(476 lb) (U49). When loading within this
weight limit, keep the following in mind:

● Cargo and accessory weight

should be kept as low and close to
the motorcycle as possible. Make
sure to distribute the weight as
evenly as possible on both sides of
the motorcycle to minimize imbal­ance or instability.

● Shifting weights can create a sud-

den imbalance. Make sure that ac­cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.

● Never attach any large or heavy

items to the handlebar, front fork,
or front fender. These items, in­cluding such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slow
steering response.

Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha cannot
test all other accessories that may be
available, you must personally be re­sponsible for the proper selection, in­stallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any ac­cessories.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.

● Never install accessories or carry

cargo that would impair the perfor­mance of your motorcycle. Care­fully inspect the accessory before
using it to make sure that it does
not in any way reduce ground
clearance or cornering clearance,
limit suspension travel, steering
travel or control operation, or ob­scure lights or reflectors.

• Accessories fitted to the handle­bar or the front fork area can
create instability due to improper
weight distribution or aerody­namic changes. If accessories

1-3

are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.

• Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerody­namic effects. Wind may at­tempt to lift the motorcycle, or
the motorcycle may become un­stable in cross winds. These ac­cessories may also cause
instability when passing or being
passed by large vehicles.

• Certain accessories can dis­place the operator from his or
her normal riding position. This
improper position limits the free­dom of movement of the opera­tor and may limit control ability,
therefore, such accessories are
not recommended.

● Use caution when adding electri-

cal accessories. If electrical acces­sories exceed the capacity of the
motorcycle’s electrical system an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.

SAFETY INFORMATION

Gasoline and exhaust gas

● GASOLINE IS HIGHLY FLAMMA-

BLE:

1

• Always turn the engine off when
refueling.

• Take care not to spill any gaso­line on the engine or exhaust
system when refueling.

• Never refuel while smoking or in
the vicinity of an open flame.

● Never start the engine or let it run

for any length of time in a closed
area. The exhaust fumes are poi­sonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has ad­equate ventilation.

● Always turn the engine off before

leaving the motorcycle unattended
and remove the key from the main
switch. When parking the motor­cycle, note the following:

• The engine and exhaust system
may be hot, therefore, park the
motorcycle in a place where pe­destrians or children are not like­ly to touch these hot areas.

• Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.

• Do not park the motorcycle near
a flammable source, (e.g., a ker­osene heater, or near an open
flame), otherwise it could catch
fire.

● When transporting the motorcycle

in another vehicle, make sure that
it is kept upright. If the motorcycle
should lean over, gasoline may
leak out of the carburetor or fuel
tank.

● If you should swallow any gaso-

line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.

CAUTION:

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 pump octane number
[(R+M)/2] of 86 or higher, or 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.

Gasohol

There are two types of gasohol: gaso­hol containing ethanol and that contain­ing methanol. Gasohol containing
ethanol can be used if the ethanol con­tent does not exceed 10%. Gasohol
containing methanol is not recom­mended by Yamaha because it can
cause damage to the fuel system or ve­hicle performance problems.

Adjusting the front fork

This front fork is equipped with air
valves for adjusting the spring rate.

EWA10180

WARNING

Always adjust both fork legs equal­ly, otherwise poor handling and loss
of stability may result.

Adjust the spring rate as follows.

1. Elevate the front wheel by placing
the vehicle on the centerstand.

NOTE:

When checking and adjusting the air
pressure, there should be no weight on
the front end of the vehicle.

2. Remove the air valve cap from
each fork leg.

INSTRUMENT AND CONTROL FUNCTIONS

4. To increase the spring rate and
thereby harden the suspension, in­crease the air pressure with an air
pump or compressed air. To de­crease the spring rate and thereby
soften the suspension, decrease
the air pressure by pushing each

3

valve stem down.

Spring rate:

Minimum/standard (soft):

Air pressure = 40 kPa (5.7 psi) (0.4
kgf/cm²)

Maximum (hard):

Air pressure = 100 kPa (14 psi)
(1.0 kgf/cm²)

CAUTION:

Never exceed the maximum air pres­sure, otherwise the front fork oil
seals may become damaged.

WARNING

There must be no difference in air
pressure between the left and right
fork legs, otherwise poor handling
and loss of stability may result.

WARNING

These shock absorbers contain
highly pressurized nitrogen gas. For
proper handling read and under­stand the following information be­fore handling the shock absorbers.
The manufacturer cannot be held re-

sponsible for property damage or
personal injury that may result from
improper handling.

● Do not tamper with or attempt to

open the gas cylinders.

● Do not subject the shock ab-

sorbers to an open flame or oth­er high heat sources, otherwise
they may explode due to exces­sive gas pressure.

● Do not deform or damage the

gas cylinders in any way, as this
will result in poor damping per­formance.

● Always have a Yamaha dealer

service the shock absorbers.

V-Boost

3

The V-Boost is a vital part of the engine
and requires very sophisticated adjust­ment. Adjustment should be left to a
Yamaha dealer who has the profes­sional knowledge and experience to do
so.

CAUTION:

The V-Boost was set at the Yamaha
factory after many tests. If the set­tings are changed by someone with­out sufficient technical knowledge,
poor engine performance and dam­age may result.

The V-Boost operation can be heard
when the main switch is turned on.

CAUTION:

If the V-Boost does not operate, ask
a Yamaha dealer to inspect it.

EAU15300

Sidestand

The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.

NOTE:

The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.)

EWA10240

WARNING

The vehicle must not be ridden with
the sidestand down, or if the side­stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon­sibility of raising the sidestand be­fore starting off. Therefore, check
this system regularly as described
