
Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent motorcycle license.
• Make sure that you are qualified and that you only lend your mo-
torcycle to other qualified oper-
ators.
• Know your skills and limits. Staying within your limits may
help you to avoid an accident.
• We recommend that you prac- tice riding your motorcycle
where there is no traffic until you
have become thoroughly famil-
iar 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
turn due to excessive speed or un-
dercornering (insufficient lean an-
gle for the speed).
• Always obey the speed limit and never travel faster than warrant-
ed by road and traffic condi-
tions. • 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 foot-
rests during operation to main-
tain 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 motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is the
single most critical factor in the pre-
vention 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 abra-
sions or lacerations.
 Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or wheels
and cause injury or an accident.
 Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause
burns.
 A passenger should also observe
the above precautions.

d Car bon Monoxi de Poisonin g
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be pres-
ent even if you do not see or smell any
engine exhaust. Deadly levels of car-
bon monoxide can collect rapidly and
you can quickly be overcome and un-
able to save yourself. Also, deadly lev-
els of carbon monoxide can linger for
hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.  Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
 Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports. 
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loa din g
Adding accessories or cargo to your
motorcycle can adversely affect stabil-
ity and handling if the weight distribu-
tion 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, along with the information about
accessories below, are some general
guidelines to follow if loading cargo to
your motorcycle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloa ded vehicle
coul d cause an acci dent. 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. Se-
curely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the mo-
torcycle to minimize imbalance or
instability.
 Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the motorcycle
before riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• 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

1operator and may limit control
ability, therefore, such accesso-
ries are not recommended.
 Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle’s electrical sys-
tem, an electric failure could re-
sult, which could cause a
dangerous loss of lights or engine
power.
Aftermarket Tires an d Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. See page 7-15
for tire specifications and for informa-
tion on servicing and replacing your
tires.
Transportin g the Motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle. 
Remove all loose items from the
motorcycle.
 Check that the fuel cock (if
equipped) is in the off position and
that there are no fuel leaks.
 Shift the transmission into gear
(for models with a manual trans-
mission).
 Secure the motorcycle with tie-
downs or suitable straps that are
attached to solid parts of the mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
 The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the mo-
torcycle will not bounce exces-
sively during transport.

“D-MODE”“D-MODE” is an electronically con-
trolled engine performance system.
WARNING
EWA18440
Do not change the d rive mo de while
the vehicle is movin g.The “D-MODE” system consists of 4
different control maps which regulate
engine response and output, thus pro-
viding you with a selection of modes to
fit your preferences and the riding envi-
ronment.
D-MODE 1 - Sporty engine response
D-MODE 2 - Moderate engine re-
sponse
D-MODE 3 - Mild engine response
D-MODE 4 - Mild engine response and
limits engine outputTIP The current “D-MODE” setting is
shown in the MODE display. (See
page 4-11.)
 The current “D-MODE” setting is
saved when the vehicle is turned
off. 
The “D-MODE” is controlled by
the MODE switches, see page 4-4
for more information.
EAU91432
“TCS-MODE”This model is equipped with adjustable
traction, slide, and lift control systems
(TCS, SCS and LIF). These are
grouped together into “TCS-MODE”.
“TCS-MODE” has 4 settings:
“TCS-MODE M” is customizable in the
settings MENU, see page 4-15.
TCS
The traction control system helps
maintain traction when accelerating. If
sensors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The stability
control indicator light “ ” flashes to
let the rider know that traction control
has engaged.

This traction control system automati-
cally adjusts according to the vehicle’s
lean angle. To maximize acceleration,
when the vehicle is upright a lesser
amount of traction control is applied.
When cornering, a greater amount of
traction control is applied.
TIP
The traction control system may
engage when the vehicle travels
over a bump.
 You may notice slight changes in
engine and exhaust sounds when
the traction control or other sys-
tems engage.
 The traction control system can
only be turned off by setting “TCS-
MODE” to “OFF”, using the MODE switches. See page 4-4 for more
information on “TCS-MODE”.
 When “TCS-MODE” has been set
to “OFF”, the TCS, SCS and LIF
systems are all turned off togeth-
er.
WARNING
EWA15433
The traction control system is not a
substitute for ri din g appropriately
for the con ditions. Traction control
cannot prevent loss of traction d ue
to excessive spee d when enterin g
turns, when acceleratin g har d at a
sharp lean an gle, or while brakin g,
an d cannot prevent front wheel slip-
pin g. As with any vehicle, approach
surfaces that may be slippery with
caution an d avoi d especially slip-
pery surfaces.When the vehicle power is on, the trac-
tion control system automatically turns
on. The traction control system can be
turned on or off manually only when
the key is in the “ON” position and the
motorcycle is stopped.
TIP
the rear wheel if the motorcycle gets
stuck in mud, sand, or other soft sur-
faces.NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 7-15.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.SCS
The slide control system regulates en-
gine power output when a sideward
slide is detected in the rear wheel. It
adjusts power output based on data
from the IMU (Inertial Measurement
Unit). This system supports the TCS to
contribute to a smoother ride.
LIF
The lift control system reduces the rate
at which the front wheel rises during
extreme acceleration, such as during
starts or out-of-corner exits. When
front-wheel lift is detected, engine

EAU91340
QSSThe quick shift system allows for clutch
lever-less, electronically-assisted shift-
ing. When the sensor on the shift rod
detects the appropriate motion in the
shift pedal, engine power output is mo-
mentarily adjusted to allow for the gear
change to occur.
QSS does not operate when the clutch
lever is pulled, therefore normal shifting
can be done even when QSS is set to
on. Check the QS indicator for current
status and usability information.
