A Few Words About Safety

Your safety, and the safety of others, is very

important. Operating this motorcycle 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 motorcycle. You

must use your own good judgement.

You will find important safety information in a

variety of forms, including:

●Safety labels on the motorcycle

●

Safety Messages preceded by a safety alert

symbol and one of three signal words:

DANGER, WARNING, or CAUTION.

These signal words mean:

3DANGER

You WILL be KILLED or SERIOUSLY

HURT if you don’t follow instructions.

3WARNING

You CAN be KILLED or SERIOUSLY

HURT if you don’t follow instructions.

3CAUTION

You CAN be HURT if you don’t follow

instructions.

Other important information is

damage to your motorcycle,

other property, or the

environment.

This section contains important information for safe riding of your motorcycle.

Please read this section carefully.

Motorcycle 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.

Always Wear a Helmet

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 motorcycle helmet and

protective apparel. 2P. 10

Before Riding

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 motorcycle helmet and protective

apparel. Instruct your passenger on holding

onto the seat strap or your waist, leaning with

you in turns, and keeping their feet on the

footpegs, even when the motorcycle is stopped.

Take Time to Learn & Practice

Even if you have ridden other motorcycles,

practice riding in a safe area to become familiar

with how this motorcycle works and handles,

and to become accustomed to the motorcycle's

size and weight.

Continued

Ride Defensively

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 Easy to See

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.

Ride within Your Limits

Never ride beyond your personal abilities or

faster than conditions warrant. Fatigue and

inattention can impair your ability to use good

judgement and ride safely.

Don't Drink and Ride

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.

Keep Your Honda in Safe Condition

It's important to keep your motorcycle properly

maintained and in safe riding condition.

Inspect your motorcycle before every ride and

perform all recommended maintenance. Never

exceed load limits (2P. 15), and do not modify

your motorcycle or install accessories that

would make your motorcycle unsafe (2P. 14).

If You are Involved in a Crash

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 the (Off) position, and

evaluate the condition of your motorcycle.

Inspect for fluid leaks, check the tightness of

critical nuts and bolts, and check the handlebar,

control levers, brakes, and wheels. Ride slowly

and cautiously.

Your motorcycle may have suffered damage

that is not immediately apparent. Have your

motorcycle thoroughly checked at a qualified

service facility as soon as possible.

Carbon Monoxide Hazard

Exhaust contains poisonous carbon monoxide, a

colourless, 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 motorcycle inside a garage or

other enclosure.

3WARNING

Running the engine of your motorcycle

while in an enclosed or even partially

enclosed area can cause a rapid build-

up of toxic carbon monoxide gas.

Breathing this colourless, odorless gas

can quickly cause unconsciousness and

lead to death.

Only run your motorcycle's engine

when it is located in a well ventilated

area outdoors.

Riding Precautions

Running-in Period

During the first 500 km (300 miles) of running,

follow these guidelines to ensure your

motorcycle's future reliability and performance.

●Avoid full-throttle starts and rapid

acceleration.

●Avoid hard braking and rapid down-shifts.

●Ride conservatively.

Brakes

Observe the following guidelines:

●Avoid excessively hard braking and

downshifting.

uSudden braking can reduce the

motorcycle's stability.

uWhere possible, reduce speed before

turning; otherwise you risk sliding out.

●Exercise caution on low traction surfaces.

uThe tyres slip more easily on such

surfaces and braking distances are

longer.

●Avoid continuous braking.

uRepeated 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.

#

Anti-lock Brake System (ABS)

This model is equipped with an Anti-lock Brake

System (ABS) designed to help prevent the

brakes from locking up during hard braking.

The ABS functions with information provided by

the IMU (Inertia Measurement Unit).

●ABS does not reduce braking distance. In

certain circumstances, ABS may result in a

longer stopping distance.

●ABS does not function at speeds below 10

km/h (6 mph).

●The brake lever and pedal may recoil slightly

when applying the brakes. This is normal.

●Always use the recommended front/rear

tyres and sprockets to ensure correct ABS

operation.

#

Engine Braking

Engine braking helps slow your motorcycle

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.

Riding Precautions

Motorcycle Safety

12

Parking

●Park on a firm, level surface.

●If you must park on a slight incline or loose

surface, park so that the motorcycle 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 handlebar and remove the key when

leaving the motorcycle unattended.

Use of an anti-theft device is also

recommended.

#

Parking with the Side Stand

1.

Stop the engine.

2.

Push the side stand down.

3.

Slowly lean the motorcycle to the left until its

weight rests on the side stand.

4.

Turn the handlebar fully to the left.

uTurning the handlebar to the right

reduces stability and may cause the

motorcycle to fall.

5.

Turn the ignition switch to the (Lock)

position and remove the key. 2P. 42

Refuelling and Fuel Guidelines

Follow these guidelines to protect the engine,

fuel system and catalytic converter:

●Use only unleaded petrol.

●Use recommended octane number. Using

lower octane petrol will result in decreased

engine performance.

●Do not use fuels containing a high

concentration of alcohol. 2P. 127

●Do not use stale or contaminated petrol or

an oil/petrol mixture.

●Avoid getting dirt or water in the fuel tank.
