A Few Words About Safety
Your safety, and the safety of others, is very
important. Operating this vehicle safely is
an important responsibility.
To help you make informed decisions about
safety, we have provided operating
procedures and other information on safety
labels and in this manual. This information
alerts you to potential hazards that could
hurt you or others.
Of course, it is not practical or possible to
warn you about all hazards associated with
operating or maintaining a vehicle. You
must use your own good judgment.
You will find important safety information
in a variety of forms, including:
● Safety labels on the vehicle
● Safety Messages preceded by a safety
alert symbol and one of three signal
words: DANGER, WARNING, or
CAUTION.
These signal words mean:
DANGER
You WILL be KILLED or SERIOUSLY
HURT if you don’t follow instructions.
WARNING
You CAN be KILLED or SERIOUSLY
HURT if you don’t follow instructions.
CAUTION
You CAN be HURT if you don’t follow
instructions.
Other important information is
provided under the following
titles:
NOTICE

Vehicle Safety
Safety Guidelines
Follow these guidelines to enhance your
safety:
● Perform all routine and regular
inspections specified in this manual.
● Stop the engine and keep sparks and
flame away before filling the fuel tank.
● Do not run the engine in enclosed or
partly enclosed areas. Carbon monoxide
in exhaust gases is toxic and can kill you.
● Do not ride the vehicle with the mirrors
folded inward, as the mirrors can
interfere with the handlebar controls.
It’s a proven fact: helmets and protective
apparel significantly reduce the number
and severity of head and other injuries. So
always wear an approved helmet and
protective apparel.
2 P. 10
Make sure that you are physically fit,
mentally focused and free of alcohol and
drugs.
Check that you and your passenger are
both wearing an approved helmet and
protective apparel. Instruct your passenger
on holding onto the grab rails or your
waist, leaning with you in turns, and
keeping their feet on the step boards, even
when the vehicle is stopped.
Even if you have ridden other vehicles,
practice riding in a safe area to become
familiar with how this vehicle works and
handles, and to become accustomed to the
vehicle’s size and weight.
We recommend that all riders take a
certified course approved by the
Motorcycle Safety Foundation (MSF). New
riders should start with the basic course,
and even experienced riders will find the
advanced course beneficial.
For information about the MSF training
course nearest you, call the national toll-
free number:
(800) 446-9227.
Other riding tips can be found in the
You and Your Motorcycle Riding Tips
booklet that came with your vehicle.
WARNINGWARNING
Riding the vehicle with the mirrors
folded inward can interfere with
your ability to safely operate the
vehicle and could lead to a crash
which you can be seriously hurt or
killed.
Make sure the mirrors are fully
extended outward and secured in
place before riding the vehicle.

Vehicle Safety
Always pay attention to other vehicles
around you, and do not assume that other
drivers see you. Be prepared to stop quickly
or perform an evasive maneuver.
Make yourself more visible, especially at
night, by wearing bright reflective clothing,
positioning yourself so other drivers can see
you, signaling before turning or changing
lanes, and using your horn when necessary.
Never ride beyond your personal abilities or
faster than conditions warrant. Fatigue and
inattention can impair your ability to use
good judgment and ride safely.
Alcohol and riding don’t mix. Even one
alcoholic drink can reduce your ability to
respond to changing conditions, and your
reaction time gets worse with every
additional drink. Don’t drink and ride, and
don’t let your friends drink and ride either.
It’s important to keep your vehicle properly
maintained and in safe riding condition.
Inspect your vehicle before every ride and
perform all recommended maintenance.
Never exceed load limits (
2 P. 17), and do
not modify your vehicle or install
accessories that would make your vehicle
unsafe (
2 P. 17).
Personal safety is your first priority. If you or
anyone else has been injured, take time to
assess the severity of the injuries and
whether it is safe to continue riding. Call
for emergency assistance if needed. Also
follow applicable laws and regulations if
another person or vehicle is involved in the
crash.
If you decide to continue riding, first turn
the ignition switch to OFF, and evaluate the
condition of your vehicle. Inspect for fluid
leaks, check the tightness of critical nuts
and bolts, and check the handlebars,
control levers, brakes, and wheels. Ride
slowly and cautiously.
Your vehicle may have suffered damage
that is not immediately apparent. Have
your vehicle thoroughly checked at a
qualified service facility as soon as possible.

Vehicle Safety
Unlike standard vehicles, or its manual
transmission sibling, the GL1800BD/D/DA
with dual clutch transmission does not have
a clutch lever that would provide you with
an additional means to control the engine
power being transmitted to the rear wheel.
Thus, in the unlikely event that you
experience a stuck throttle or other
unintended application of power to the
rear wheel, you should shut down the
engine by use of the engine stop switch
(
2 P. 52).
By moving this switch to the (Stop)
position, you will immediately stop the
engine but maintain all electrical system
functions, including lights and indicators.
Exhaust contains poisonous carbon
monoxide, a colorless, odorless gas.
Breathing carbon monoxide can cause loss
of consciousness and may lead to death.
If you run the engine in confined or even
partly enclosed area, the air you breathe
could contain a dangerous amount of
carbon monoxide.
Never run your vehicle inside a garage or
other enclosure.

Vehicle Safety
This section describes some important safety
precautions. For airbag system components
and features, see “Airbag System.”
2 P. 64
The airbag system is an integral part of your
vehicle and is covered by your new vehicle
warranty.
The most important things you need to know
about your airbag are:
● The airbag has a limited but very important
role.
The airbag can reduce the severity of
injuries and help save your life in certain
severe frontal impacts. It cannot prevent all
injuries or deaths that can occur in a crash,
and some crashes are too severe for any
safety feature or system to prevent death.
● The airbag is designed to deploy in a severe
head-on or nearly head-on frontal impact.
The impact can be with another vehicle or
an object, such as a concrete highway
barrier. A severe frontal impact is one in
which the rider would be thrown forward
off the front of the vehicle.
● The airbag might deploy in a severe angled
frontal collision, or in a sideswipe, or if the
vehicle underrides the rear of another
vehicle.
However, because there are many variables
in a collision, the airbag might not be able
to reduce the severity of injuries to the
rider.
● The airbag might deploy if the front tire
drops into a sharp depression, such as a
pothole, or strikes a hard raised object,
such as a curb.
A brief high rate of deceleration can cause
the airbag to deploy, even though it would
not be needed.
● The airbag is designed to help protect the
rider.
It is not designed to help protect a
passenger.
● The airbag is not intended to replace a
helmet.
Helmets have proven effective in reducing
the severity of head injuries in all types of
crashes. So always wear a helmet, and
make sure a passenger wears one as well.
There are several situations in which the vehicle
airbag should not deploy. Four of the more
common situations are discussed here.
● If a rider is traveling at a moderate speed
and has a minor frontal collision, such as
running into the rear of a car slowing down
ahead, or stopped at a traffic light, the rate
of deceleration should be low enough for
the rider to either stay on the vehicle or
receive less than severe injuries to the head
or chest.
● Being struck in the side or rear by another
vehicle can result in very serious injuries.
But since the sensors are attached to the
frame, such a crash cannot be detected by
the sensors. Therefore, the airbag should
not deploy, and it would not be helpful to
the rider even if it did deploy.
● Another situation that should not result in
airbag deployment is if the vehicle slides
out and goes down on a slippery surface.
Again, the crash would not be detected or
determined to be a severe frontal impact,
and the airbag would not benefit the rider
even if it did deploy.

GL1800DA
continued

Safety Precautions
12
Vehicle Safety
● Finally, if the vehicle is involved in a
sideswipe with a stationary object, such as
a concrete median barrier, or with another
vehicle traveling in the same direction, as
illustrated here, the airbag should not
deploy.
❙
Important Safety Precautions
● Do not install or temporarily attach any
items, such as a map holder, over the
airbag cover or in the area between the
rider’s seat and the handlebars.
This could prevent the airbag from
deploying properly, or cause items to be
propelled by the airbag and possibly hurt
someone.
● Do not tamper with any system
components, including the wires or
connectors.
Doing so could prevent the airbag system
from operating properly or cause
unintended airbag deployment and
possibly serious injury.
● Do not attempt to remove any airbag
components — even temporarily.
This could result in unintended airbag
deployment and injury.
What you should do: Follow all
recommendations in this owner’s manual.

Riding Precautions
13
Vehicle Safety
Riding Precautions
During the first 300 miles (500 km) of
running, follow these guidelines to ensure
your vehicle’s future reliability and
performance.
● Avoid full-throttle starts and rapid
acceleration.
● Avoid hard braking and rapid down-
shifts.
● Ride conservatively.
Observe the following guidelines:
● Avoid excessively hard braking and
downshifting.
u Sudden braking can reduce the
vehicle’s stability.
u Where possible, reduce speed before
turning; otherwise you risk sliding out.
● Exercise caution on low traction surfaces.
u The tires slip more easily on such
surfaces and braking distances are
longer.
● Avoid continuous braking.
u Repeated braking, such as when
descending long, steep slopes can
seriously overheat the brakes,
reducing their effectiveness. Use
engine braking with intermittent use
of the brakes to reduce speed.
● For full braking effectiveness, operate
both the front and rear brakes together.
❙
Combined ABS
Your vehicle is equipped with a brake
system that distributes the braking force
between the front and rear brakes.
The distribution of the braking force is
applied to both front and rear brakes when
operating the lever and/or pedal.
For full braking effectiveness, operate both
the front and rear brakes together.
The brake feel changes according to the
selected riding mode.
2
P. 120
This model is also equipped with an Anti-
lock Brake System (ABS) designed to help
prevent the brakes from locking up during
hard braking.
● ABS does not reduce braking distance. In
certain circumstances, ABS may result in
a longer stopping distance.
● ABS does not function at speeds below
3 mph (5 km/h).
● The brake lever and pedal may recoil
slightly when applying the brakes. This is
normal.
● Always use the recommended tires to
ensure correct ABS operation.
Break-in Period
Brakes

Riding Precautions
14
Vehicle Safety
❙
Engine Braking
Engine braking helps slow your vehicle
down when you release the throttle. For
further slowing action, downshift to a
lower gear. Use engine braking with
intermittent use of the brakes to reduce
speed when descending long, steep slopes.
❙
Wet or Rainy Conditions
Road surfaces are slippery when wet, and
wet brakes further reduce braking
efficiency.
Exercise extra caution when braking in wet
conditions.
If the brakes get wet, apply the brakes
while riding at low speed to help them dry.
If you decide to ride your vehicle in the rain,
fog, or other bad-weather conditions, ride
carefully. Wet road surfaces reduce
traction, especially in turns, and increase
stopping distances when you brake.
If the weather turns bad while you are
riding, take extra care and do not use cruise
control.
When riding in the rain, we recommend
you adjust your windscreen height below
eye level, if possible, for better visibility.
2 P. 136
Riding in Bad Weather

Riding Precautions
15
Vehicle Safety
● Park on a firm, level surface.
● If you must park on a slight incline or
loose surface, park so that the vehicle
cannot move or fall over.
● Make sure that high-temperature parts
cannot come into contact with
flammable materials.
● Do not touch the engine, muffler, brakes
and other high-temperature parts until
they cool down.
● To reduce the likelihood of theft, always
lock the handlebars (2 P. 55) and leave
your vehicle while taking the Honda
SMART Key with you. Deactivate the
Honda SMART Key system if necessary.
2 P. 56
Use of an anti-theft device is also
recommended.
❙
Parking with the Side Stand or Center
Stand
1.
Stop the engine.
2.
Using the side stand
Push the side stand down.
Slowly lean the vehicle to the left until its
weight rests on the side stand.
Using the center stand
To lower the center stand, stand on the
left side of the vehicle. Hold the left
handle grip and the left grab rail. Press
down on the tip of the center stand with
your right foot and, simultaneously, pull
up and back.
3.
Turn the handlebars fully to the left.
uTurning the handlebars to the right
reduces stability and may cause the
vehicle to fall.
4.
Turn the ignition switch to (Lock).
2 P. 55
Then, leave your vehicle while taking the
Honda SMART Key with you. Deactivate
the Honda SMART Key system if
necessary.
2 P. 56
Follow these guidelines to protect the
engine, fuel system and catalytic converter:
● Use only unleaded gasoline.
● Use recommended octane number.
Using lower octane gasoline will result in
decreased engine performance.
● Do not use fuels containing a high
concentration of alcohol.
2P. 231
● Do not use stale or contaminated
gasoline or an oil/gasoline mixture.
● Avoid getting dirt or water in the fuel
tank.

Vehicle Safety
When the Honda selectable torque control
(Torque Control) detects rear wheel spin
during acceleration, the system will limit
the amount of torque applied to the rear
wheel based on the Torque Control level
set according to the selected riding mode.
Torque Control will allow some wheel spin
during acceleration at the lower Torque
Control levels settings. Select a riding mode
that is appropriate for riding conditions.
2 P. 120
Torque Control does not work during
deceleration and will not prevent the rear
wheel from skidding due to engine
braking. Do not close the throttle suddenly,
especially when riding on slippery surfaces.
Torque Control may not compensate for
rough road conditions or rapid throttle
operation. Always consider road and
weather conditions, as well as your skills
and condition, when applying throttle.
If your vehicle gets stuck in mud, snow or
sand, it may be easier to free it with the
Torque Control temporarily switched off.
2 P. 31
Temporarily turning off Torque Control also
may help you maintain control and balance
when riding on off-road terrain.
Always use the recommended tires to
ensure correct Torque Control operation.

Airbag System
The Airbag System can help cushion the
impact force to the rider’s head and upper
body in certain severe frontal impacts.
For safety precautions, see “Airbag
system.”
(P11)
How Rider Injuries Occur in a
Frontal Crash
“SPEED KILLS,” a saying goes. But not all
vehicle injuries occur at high speeds, and
speed alone does not cause injuries.
In fact, the main cause of injuries in a
collision is a rapid decrease in speed, caused
by the rider impacting an object, such as
another vehicle or the ground. As another
saying goes, “It’s not how fast you go, it’s
how hard you hit.”
Consider, for example, what happens
when a vehicle and rider crash into a
parked car at 30 mph (50 km/h).
• In a 30 mph (50 km/h), head-on crash
into the side of a stationary car, the
vehicle will come to a stop in about 1/
10th of a second-nearly as fast as the
blink of an eye.
Without an airbag, the rider would
continue forward at 30 mph (50 km/h)
until he strikes the car or the ground
with a force that could cause very serious
or fatal injuries.
• In the same situation with an airbag-
equipped vehicle, the bag would slow
the rider’s forward movement and
absorb some of his kinetic energy.*
As a result, the rider would impact the car
and/or the ground at a lower speed and
with less force, and have a better chance of
surviving the crash.
*Kinetic energy (KE) is the energy of motion. For a
rider, it’s a combination of the rider’s mass (m) or
weight, and his speed (v).
Mathematically, KE = (m x v2)/2. At 30 mph (50
km/h), a rider’s kinetic energy is four times greater
than at 15 mph (24 km/h). At 45 mph (72 km/h), it
would be nine times greater.
At 60 mph (100 km/h), it would be sixteen times
greater.
• A crash into a solid barrier at 30 mph (50
km/h) may not seem very serious, but for
the rider it would be similar to falling
from a third-story building directly onto
pavement.
GL1800DA

Airbag System Components
Your vehicle airbag system includes:
An airbag that is stored forward of the rider’s
seat, under a cover marked .
The impact sensors that measure the rate of
deceleration during a frontal impact are
located on the left and right of the main
frame under the rider seat.
The control unit evaluates data from the
impact sensors and determines whether or
not the airbag should deploy.
The system continually monitors
information about the sensors, the control
unit, and the airbag inflator whenever the
ignition is in the ON position.

Operation Guide

Airbag System (Continued)
How The Airbag System Works
If you ever have a frontal impact, the
impact sensors will detect the vehicle’s
deceleration and send that information to
the control unit.
If the rate of deceleration is high enough,
the control unit will signal the airbag to
instantly inflate.
As the rider’s head and upper body press
into the airbag, the bag immediately begins
deflating, through vents located at the
bottom of the bag.
The airbag slows down the rider’s forward
movement and absorbs some of the rider’s
kinetic energy.
When the rider eventually separates from
the vehicle and contacts the opposing
object or the ground, the forward speed of
the rider and the resulting force of the
impact will be much lower than they would
be without the airbag.
Airbag System Service
Your airbag system is well protected from
the elements. There is no need to take any
special precautions to protect it from rain,
snow, or temperature extremes.
The airbag system is also virtually
maintenance free, and there are no parts
you can safely service. However, you must
have your vehicle checked by a Honda
dealer if:
• The AIRBAG indicator alerts you to a
potential problem with the system. The
indicator, located in the instrument
panel, should come on briefly when you
turn the ignition switch to ON. If it does
not come on, or it comes on and stays
on, or it comes on while you are riding,
the airbag may not deploy when you
need it.
• The airbag ever inflates. Any airbag that
has deployed must be replaced along
with the control unit and other related
parts. Do not try to remove or replace
the airbag by yourself. This must be done
by a Honda dealer.

Dual Clutch Transmission
In order to respond to rider demands in a
broad range of situations, the transmission
is equipped with two operating modes, AT
MODE (D) (automatic shift for regular
operation); and MT MODE (for 7-speed
manual operation), which delivers the same
shift feel as a manual transmission.
u Always use the recommended tires to
ensure correct Dual Clutch Transmission
operation.
The Dual Clutch Transmission system runs a
self check immediately after starting the
engine.
“-” appears in the gear position indicator
for a few seconds, then goes out.
While “-” appears, you cannot shift into
gear.
Neutral (N):
Neutral is selected automatically
when you turn the ignition switch to ON.
If neutral is not selected when you
turn the ignition switch to ON:
u Turn the ignition OFF and ON again.
You may hear (click) noises when the
transmission shifts to Neutral (N). This is
normal.
u If the Neutral (N) is still not selected after
turning the ignition switch on, start the
engine while applying the brake with
side stand raised. If Neutral (N) is still not
selected.
(P185)
When you can change between
Neutral (N) and AT MODE (D):
u Vehicle is stopped and the engine is
idling.
u Throttle is completely closed. It is not
possible to change from Neutral (N) to
AT mode (D) while the throttle is applied.
u You cannot change between Neutral (N)
and AT MODE (D) while the wheels are
rotating.
u Side stand is raised.
AT MODE (D): In this mode the gears are
shifted automatically according to your
riding conditions.
And also using the shift up switch (+) or
shift down switch (-), you can temporarily
shift up or down. These switches are
convenient when you want to temporarily
down-shift in front of a curve, etc.
(P116)
MT MODE: You can choose between 7
gears in this mode.

Hill Start Assist
The Hill Start Assist (HSA) temporarily keeps
the vehicle from rolling backward (or
forward) if the brake lever or pedal is
released when stopped on an incline such
as a hill or parking lot slope. Brake hydraulic
pressure is maintained for about 3 seconds
after releasing the brake lever or pedal. This
helps keep the vehicle from rolling
backward (or forward) when first opening
the throttle grip, thereby assisting smooth
movement and lessening the burden
placed on the rider.
HSA is not a replacement for the parking
brake.
Hill start assist (HSA) indicator:
Comes on in white when the HSA is ready
to work, and flashes while the HSA is

Checking the Air Pressure
Even though your vehicle is equipped with
tire pressure monitoring system (TPMS),
visually inspect your tires and use an air
pressure gauge to measure the air pressure
at least once a month or any time you think
the tires look low. Always check air
pressure when your tires are cold.
Do not adjust tire pressure using the values
indicated on the tire pressure gauge of the
INFO 1 display.
The tire pressure values indicated on the
tire pressure gauge of the INFO 1 display
may not match actual values, because the
tire pressure gauge indication is not
updated instantly and is updated only at a
certain period.
Even if the direction of the valve stem is
changed, do not return it to the original
position. Have your vehicle inspected by
your dealer.
❙
Inspecting for Damage
Inspect the tires for
cuts, slits, or cracks
that exposes fabric
or cords, or nails or
other foreign
objects embedded
in the side of the
tire or the tread. Also inspect for any
unusual bumps or bulges in the side walls
of the tires.

2 P. 237, 239
Follow these guidelines whenever you
replace tires.
● Use the recommended tires or
equivalents of the same size,
construction, speed rating, and load
range.
● Have the wheel balanced with Honda
Genuine balance weights or equivalent
after the tire is installed.
● Do not install a tube inside a tubeless tire
on this vehicle. Excessive heat build-up
can cause the tube to burst.
● Use only tubeless tires on this vehicle.
The rims are designed for tubeless tires,
and during hard acceleration or braking,
a tube-type tire could slip on the rim and
cause the tire to rapidly deflate.
● Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem. You must use
TPMS specific wheels. Not using TPMS
specific wheels can cause an air leak, a
tire pressure monitoring system failure,
or both.
WARNINGWARNING
Riding on tires that are excessively
worn or improperly inflated can
cause a crash in which you can be
seriously hurt or killed.

the tires reach 5 years old. It is also
recommended that all tires be removed
from service after 10 years from the date of
manufacture, regardless of their condition
or state of wear.
The last four digits of the TIN (tire
identification number) indicate the date of
manufacture.

ride, the low tire pressure indicator will go
off in some cases. It is still necessary to
check the air pressures of both tires after
the tires cool because air in the tires is
expanded with heat.
If the low tire pressure indicator does not
go off after inflating the tires to the
specified values, have your dealer to check
the system as soon as possible.
Riding on an underinflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Because tire pressure varies by temperature
and other conditions, the low tire pressure
indicator may turn on unexpectedly.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the rider’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level of turning on the
low tire pressure indicator.
For example, if you check and fill your tires
in a warm area, then ride in extremely cold
weather, the tire pressure will be lower
than measured and could be underinflated

Continuing to ride with high clutch temperature can
cause serious damage to the clutch.

and cause the low tire pressure indicator to
turn on. Or, if you check and adjust your
tire pressure in cooler conditions, and ride
into extremely hot conditions, the tire may
become overinflated. However, the low tire
pressure indicator will not turn on if the
tires are overinflated.
TPMS Indicator
The TPMS indicator comes on if there is a
problem with the tire pressure monitoring
system.
If this occurs, the system will shut off and
no longer monitor tire pressure.
Have the system checked by your dealer as
soon as possible.
Also the TPMS indicator may light for the
following reasons:
● Interference of other electronic devices
by using the same radio frequency.
● Using replacement wheels not equipped
with tire pressure sensors.
AIRBAG Indicator
The AIRBAG indicator comes on if there is a
problem with the airbag system.
If the indicator does not come on, or comes
and stays on when the ignition switch is
turned on, or comes on while you are
riding, have your vehicle inspected by your
dealer as soon as possible as the airbag may
not deploy when it could help save your
life.
Hill Start Assist (HSA)
Indicator
If the Hill start assist (HSA) indicator comes
on in amber in one of the following ways,
you may have a serious problem with the
HSA system.
Reduce speed and have your vehicle
inspected by your dealer as soon as
possible.
● Indicator comes on in amber while riding.
● Indicator does not come on when the
ignition switch is turned to ON.
● Indicator does not go off at speeds above
3 mph (5 km/h).
● Even when the Hill start assist (HSA)
indicator comes on in amber, your
vehicle will have normal riding ability
without HSA function.
If the Hill start assist (HSA) indicator comes
on in white while stopping the vehicle, this
is normal and the HSA is working properly.
WARNINGWARNING
Ignoring the airbag indicator can
result in serious injury or death in a
severe frontal impact if the airbag
system does not work properly.
Have your vehicle checked by a
dealer as soon as possible if the
airbag indicator alerts you to a
possible problem.

Tire Puncture
Repairing a puncture or removing a wheel
requires special tools and technical
expertise.
We recommend you have this type of
service performed by your dealer.
After an emergency repair, always have the
tire inspected/replaced by your dealer.
Emergency Repair Using a Tire
Repair Kit
If your tire has a minor puncture, you can
make an emergency repair using a tubeless
tire repair kit.
Follow the instructions provided with the
emergency tire repair kit.
Riding your vehicle with a temporary tire
repair is very risky. Do not exceed 30 mph
(50 km/h). Have the tire replaced by your
dealer as soon as possible.
Removing Wheels
Follow these procedures if you need to
remove a wheel in order to repair a
puncture.
When removing and installing the wheel,
be careful not to damage the wheel speed
sensor and pulser ring.
NOTICE
Using a puncture-repairing agent can damage the
TPMS sensors, causing the TPMS indicator to turn on.
Have your vehicle checked by your dealer as soon as
possible.
NOTICE
Use caution not to damage the TPMS sensor if an
internal plug patch must be used to repair the tire. If
you have a tire professionally repaired at a non-Honda
facility, we recommend that you have the work
checked by your dealer. TPMS wheels require special
handling when changing the tire. Failure to follow the
proper tire replacement procedure can result in
damage to the TPMS sensor.
WARNINGWARNING
Riding your vehicle with a temporary
tire repair can be risky. If the
temporary repair fails, you can crash
and be seriously injured or killed.
If you must ride with a temporary
tire repair, ride slowly and carefully
and do not exceed 30 mph (50 km/h)
until the tire is replaced.

Information
Caring for Your Vehicle
Frequent cleaning and polishing is
important to ensure the life of your Honda.
A clean vehicle makes it easier to spot
potential problems.
In particular, seawater and salts used to
prevent ice on roads promote the
formation of corrosion. Always wash your
vehicle thoroughly after riding on coastal or
treated roads.
Allow the engine, muffler, brakes, and
other high-temperature parts to cool
before washing.
1.
Rinse your vehicle thoroughly using a low
pressure garden hose to remove loose
dirt.
2.
If necessary, use a sponge or a soft towel
with mild cleaner to remove road grime.
u
Clean the windscreen, headlight lens,
panels, and other plastic components
with extra care to avoid scratching
them. Avoid directing water into the air
cleaner, muffler, and electrical parts.
3.
Thoroughly rinse your vehicle with plenty
of clean water and dry with a soft, clean
cloth.
4.
After the vehicle dries, lubricate any
moving parts.
u Make sure that no lubricant spills onto
the brakes or tires. Brake discs, pads,
drum or shoes contaminated with oil
will suffer greatly reduced braking
effectiveness and can lead to a crash.
5.
Apply a coat of wax to prevent corrosion.
u Avoid products that contain harsh
detergents or chemical solvents. These
can damage the metal, paint, and
plastic on your vehicle.
Keep the wax clear of the tires and
brakes.
u If your vehicle has any matte painted
parts, do not apply a coat of wax to
the matte painted surface.
❙
Washing Precautions
Follow these guidelines when washing:
● Do not use high-pressure washers:
u High-pressure water cleaners can
damage moving parts and electrical
parts, rendering them inoperable.
u Water in the air intake can be drawn
into the throttle body and/or enter the
air cleaner.
● Do not direct water at the muffler:
u Water in the muffler can prevent
starting and causes rust in the muffler.
● Dry the brakes:
u Water adversely affects braking
effectiveness. After washing, apply the
brakes intermittently at low speed to
help dry them.
● Do not direct water in the left saddlebag:
u Water in the left saddlebag can
damage your documents and other
belongings.
● Do not direct water at the air cleaner:
u Water in the air cleaner can prevent
the engine from starting.
Washing

Caring for Your Vehicle
221
Information
● Do not direct water near the headlight.
u The headlight's inside lens may fog
temporarily after washing or while
riding in the rain. This does not impact
the headlight function.
However, if you see a large amount of
water or ice accumulated inside the
lens(es), have your vehicle inspected
by your dealer.
● Do not use wax or polishing compounds
on matte painted surface:
u Use a soft cloth or sponge, plenty of
water, and a mild detergent to clean
matte painted surfaces. Dry with a soft
clean cloth.
Aluminum will corrode from contact with
dirt, mud, or road salt. Clean aluminum parts
regularly and follow these guidelines to avoid
scratches:
● Do not use stiff brushes, steel wool, or
cleaners containing abrasives.
● Avoid riding over or scraping against
curbs.
Follow these guidelines to prevent
scratches and blemishes:
● Wash gently using a soft sponge and
plenty of water.
● To remove stubborn stains, use diluted
detergent and rinse thoroughly with
plenty of water.
● Avoid getting gasoline, brake fluid, or
detergents on the instruments, panels, or
headlight.
Keep the windscreen raised after turning
off the electrical system to make it easy to
clean.
2 P. 136
Using plenty of water, clean the
windscreen with a soft cloth or sponge.
(Avoid using detergents or any kind of
chemical cleaner on the windscreen.) Dry
with a soft, clean cloth.
For a dirtier windscreen, use a diluted
neutral detergent with a sponge and plenty
of water. Make sure to wash off all the
detergent. (Detergent residue may cause
windscreen cracks.)
Replace the windscreen if scratches cannot
be removed and they obstruct clear vision.
Take care to keep battery electrolyte, brake
fluid, or other chemical solvents off the
windscreen and screen garnish. They will
damage the plastic.

special surface treatment to prevent
reflection and glare.
Wipe any moisture (including rainwater) on
the instrument panel with a dry, soft cloth
immediately.
Using plenty of water, clean the instrument
panel with a soft cloth or sponge.
For a dirtier instrument panel, use a diluted
neutral detergent with a sponge and plenty
of water. Make sure to wash off all the
detergent. Dry with a soft, clean cloth.
Take care to keep battery electrolyte, brake
fluid, or other chemical solvents off the
instrument panel. They will damage the
special surface treatment of the instrument

The exhaust pipe and muffler are stainless
steel but may become stained by mud or
dust.
To remove mud or dust, use a wet sponge
and a liquid kitchen abrasive, then rinse
well with clean water. Dry with chamois or
a soft towel.
If necessary, remove heat stains by using a
commercially available fine texture
compound. Then rinse by the same manner
as removing mud or dust.
When the exhaust pipe and muffler are
painted, do not use a commercially
available abrasive kitchen cleaning
compound. Use a neutral detergent to
clean the painted surface on the exhaust
pipe and muffler. If you are not sure if your
exhaust pipe and muffler are painted,
contact your dealer.
Storing Your Vehicle
If you store your vehicle outdoors, you
should consider using a full-body cover.
If you won’t be riding for an extended
period, follow these guidelines:
● Wash your vehicle and wax all painted
surfaces (except matte painted surfaces).
Coat chrome pieces with rust-inhibiting
oil.
●
Place your vehicle on its center stand and
position a block so that both tires are off
the ground.
Place your vehicle on a maintenance stand
and position a block so that both tires are
off the ground.
● After rain, remove the body cover and

You & the Environment
Owning and riding a vehicle can be
enjoyable, but you must do your part to
protect the environment.
Use a biodegradable detergent when you
wash your vehicle. Avoid aerosol spray
cleaners that contain chlorofluorocarbons
(CFCs) which damage the atmosphere’s
protective ozone layer.
Put oil and other toxic wastes in approved
containers and take them to a recycling
center.
Call your local or state office of public
works or environmental services to find a
recycling center in your area, and to get
instructions on how to dispose of non-
recyclable wastes. Do not place used
engine oil in the trash, or pour it down a
drain or on the ground. Used oil, gasoline,
coolant, and cleaning solvents contain
poisons that can hurt refuse workers and
contaminate drinking water, lakes, rivers,
and oceans.

Tire Pressure Monitoring System (TPMS) Explanation
226
Information
Tire Pressure Monitoring
System (TPMS) Explanation
Both tires should be checked monthly
when cold, and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the tire information label.
(If your vehicle has different tires than those
indicated on the vehicle tire information
label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure indicator when one or
more of your tires significantly under-
inflated.
Accordingly, when the low tire pressure
indicator illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure.
Riding on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the rider’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the low tire pressure
indicator.
Your vehicle has also been equipped with a
TPMS indicator to indicate when the system
is not operating properly. The TPMS
indicator displays the symbol “TPMS”
when illuminated.
When the TPMS indicator is illuminated,
the system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly.
Always check the TPMS indicator after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.

Emission Control Systems
227
Information
Emission Control Systems
Your vehicle engine emits combustion by-
products, including carbon monoxide (CO),
oxides of nitrogen (NOx), and hydrocarbons
(HC). Gasoline evaporation also emits
hydrocarbons. Controlling the production
of NOx, CO, and HC is important for the
environment.
The U.S. Environmental Protection Agency
(EPA), the California Air Resources Board
(CARB), and Environment and Climate
Change Canada (ECCC) require that your
vehicle comply with applicable exhaust,
crankcase, and fuel permeation emission
standards during its useful life, when
operated and maintained according to the
instructions provided.
CARB also requires that your vehicle
comply with applicable evaporative
emission requirements during its useful life,
when operated and maintained according
to the instructions provided.
Compliance with the terms of the
Distributor’s Warranties for Honda
Motorcycle Emission Control Systems is
necessary in order to maintain a valid
emissions system warranty.
The Vehicle Emission Control Information
label is attached inside the left saddlebag.

Emission Control Systems
228
Information
The EPA requires that vehicles built after
January 1, 1983 comply with applicable
noise emission standards for one year or
3,730 miles (6,000 km) after the time of
purchase when operated and maintained
according to the instructions provided.
The exhaust emission control system
includes the following components that
should not need adjustment, although
periodic inspection by your dealer is
recommended.
❙
PGM-FI System
The PGM-FI (programmed fuel injection)
system uses sequential multiport fuel
injection, and is comprised of air intake,
engine control, fuel control, and exhaust
control subsystems.
The engine control module (ECM) uses
sensors to determine how much air enters
the engine, and then controls how much
fuel to inject.
❙
Ignition Timing Control System
The ignition timing control system adjusts
the ignition timing to reduce the amount of
HC, CO, and NOx produced.
❙
Secondary Air Injection System
The secondary air injection system adds
filtered air into the exhaust gas to help
improve emission control performance.
❙
Catalytic Converters
The exhaust system contains one or more
catalytic converters. Catalytic converters
use a catalyst to convert most of the
harmful exhaust gas compounds into
harmless compounds.
Noise Emission Requirements Exhaust Emission Control System

Emission Control Systems
229
Information
An evaporative emissions control system
uses a canister filled with charcoal to
adsorb fuel vapor from the fuel tank while
the engine is off. The vapor is drawn into
the engine and burned while riding.
The engine is equipped with a closed
crankcase system to prevent discharging
crankcase emissions into the atmosphere.
Blow-by gas is returned to the combustion
chamber through the air cleaner housing
and throttle body.
The fuel tank, fuel hoses, and fuel vapor
charge hoses use fuel permeation control
technologies to prevent fuel vapor
emissions.
Tampering with these components to
reduce or defeat the effectiveness of the
fuel permeation technologies is prohibited.
❙
TAMPERING WITH THE NOISE CONTROL
SYSTEM IS PROHIBITED:
U. S. federal law prohibits, and Canadian
provincial laws may prohibit, the following
acts or the causing thereof: (1) The removal
or rendering inoperative by any person,
other than for purposes of maintenance,
repair or replacement, of any device or
element of design incorporated into any
new vehicle for the purpose of noise
control prior to its sale or delivery to the
ultimate purchaser or while it is in use; or
(2) the use of the vehicle after such device
or element of design has been removed or
rendered inoperative by any person.
❙
AMONG THOSE ACTS PRESUMED TO
CONSTITUTE TAMPERING ARE THE
FOLLOWING ACTS:
● Removal of, or puncturing the muffler,
baffles, header pipes or any other
component which conducts exhaust
gases.
● Removal of, or puncturing of any part of
the intake system.
● Lack of proper maintenance.
● Removing or disabling any emissions
compliance component, or replacing any
compliance component with a non-
compliant component.
Have your vehicle inspected and repaired
by your dealer if you experience any of the
following symptoms:
● Hard starting or stalling after starting
● Rough idling
● Misfiring or backfiring during
acceleration
● Poor engine performance and poor fuel
economy

Catalytic Converter
230
Information
Catalytic Converter
This vehicle is equipped with two three-way
catalytic converters. Each catalytic
converter contains precious metals that
serve as catalysts in high temperature
chemical reactions that convert
hydrocarbons (HC), carbon monoxide (CO),
and oxides of nitrogen (NOx) in the exhaust
gasses into safe compounds.
A defective catalytic converter contributes
to air pollution and can impair your
engine’s performance. A replacement unit
must be an original Honda part or
equivalent.
Follow these guidelines to protect your
vehicle’s catalytic converters.
● Always use unleaded gasoline. Leaded
gasoline will damage the catalytic
converters.
● Keep the engine in good running
condition.
A poorly running engine can cause the
catalytic converter to overheat causing
damage to the converter or the vehicle.
● If your engine is misfiring, backfiring,
stalling, or otherwise not running
properly, stop riding and turn off the
engine. Have your vehicle serviced as
soon as possible.

Oxygenated Fuels
231
Information
Oxygenated Fuels
Some conventional fuels blended with
alcohol or an ether compound are available
in some locales to help reduce emissions to
meet clean air standards.
These gasolines are collectively referred to
as oxygenated fuels. If you plan to use
oxygenated fuel, check that it is unleaded
and meets the minimum octane rating and
blend requirement.
The following fuel blends are EPA-
approved and have been approved for use
in your vehicle:
● Ethanol (ethyl alcohol) up to 10% by
volume.
u Gasoline containing ethanol may be
marketed under the name Gasohol.
● Methanol (methyl alcohol) up to 5% by
volume that contain cosolvents and
corrosion inhibitors to protect the fuel
system. Never use a blend containing
more than 5%.
If you accidentally fill your fuel tank with an
oxygenated fuel containing higher
percentages, you may experience
performance problems. To resolve the
problem, have your dealer drain the fuel
tank and replace with the correct fuel. Fuel
system or performance problems resulting
from the use of an oxygenated fuel
containing higher percentages are not
covered by your warranty.
If you notice any undesirable operating
symptoms or performance problems, try a
different brand of gasoline.
NOTICE
Improper use of oxygenated fuels can damage metal,
rubber, and plastic parts of your fuel system.
Oxygenated fuel can also damage paint. Damage
caused by spilled fuel is not covered by warranty.
