Motorcycle Safety
1
Important Safety Information
Your motorcycle can provide many years of
service and pleasure–if you take responsibility
for your own safety and understand the
challenges you can meet while riding.
This motorcycle has been designed for younger
riders. However, not all youngsters are
physically or emotionally ready to ride.
Therefore, before parents allow any youngster
to ride this motorcycle, we urge them to
carefully read the Important Message to
Parents beginning on page 5 and the Parents,
Youngsters and Off -Highway Motorcycles
booklet that came with the motorcycle (USA
only).
There is much that you can do to protect
yourself when you ride. You’ll find many
helpful recommendations throughout this
manual. The following are a few that we
consider to be most important.
2
Motorcycle Safety
Always Wear a Helmet
It’s a proven fact: helmets significantly reduce
the number and severity of head injuries. So
always wear an approved motorcycle helmet.
We also recommend that you wear eye
protection, sturdy boots, gloves, and other
protective gear (page 24).
Never Carry a Passenger
Your motorcycle is designed for one person
only. There are no handholds, footrests, or seat
for a second person–so never carry a passenger.
A passenger could interfere with your ability to
move around to maintain your balance and
control of the motorcycle.
Important Safety Information
Ride Off-road Only
Your motorcycle is designed and manufactured for
off-road use only. The tires are not made for
pavement, and the motorcycle does not have turn
signals and other features required for use on public
roads. If you need to cross a paved or public road,
get off and walk your motorcycle across.
Take Time to Learn and Practice
Developing off-road riding skills is a gradual,
step-by-step process. Start by practicing at low
speeds in a safe area and slowly build your
skills. Personal instruction from an experienced
rider can also be valuable.
If you need assistance, ask your dealer about
riding groups in your area.
Also be sure to read the Tips & Practice Guide
for the Off -Highway Motorcyclist booklet that
came with your motorcycle (USA only).
Be Alert for Off-road Hazards
The terrain can present a variety of challenges
when you ride off-road. Continually ‘‘read’’ the
terrain for unexpected turns, drop-offs, rocks,
ruts, and other hazards. Always keep your
speed low enough to allow time to see and react
to hazards.
Ride within Your Limits
Pushing limits is another major cause of
motorcycle crashes. Never ride beyond your
personal abilities or faster than conditions
warrant. Remember that alcohol, drugs, fatigue,
and inattention can significantly reduce your
ability to make good judgments and ride safely.
Motorcycle Safety
3
Important Safety Information
Don’t Drink and Ride
Alcohol and riding don’t mix. Even one drink
can reduce your ability to respond to changing
conditions, and your reaction time gets worse
with every additional drink. So 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.
Having a breakdown can be difficult, especially
if you are stranded off-road far from your base.
To help avoid problems, inspect your
motorcycle before every ride and perform all
recommended maintenance.

Motorcycle Safety
Important Message to Parents
Your child’s safety is very important to Honda.
That’s why we urge you to read this message
before you let any young person ride this
motorcycle. Off-road riding can be fun. But, as
with riding a bicycle, bad judgment can result
in injury, and we don’t want that to happen! As
a parent, you can help prevent accidents by
making good decisions about if, when, and how
your youngster rides this motorcycle.
Riding Readiness
The first decision you’ll need to make is
whether your youngster is ready to ride. Riding
readiness varies widely from one person to
another, and age and size are not the only
factors.
PHYSICAL ABILITY is an important
consideration. For example, riders must be big
enough to hold the motorcycle up, get on, and
comfortably sit on the seat with both feet
touching the ground. They should also be able
to easily reach and work the brakes, throttle,
and all other controls.
ATHLETIC ABILITY is necessary for riding a
motorcycle. Generally speaking, your
youngster should be good at riding a bicycle
before getting on a motorcycle. Can your
youngster judge speeds and distances while
riding a bicycle and react with proper hand and
foot actions? Anyone who does not have good
coordination, balance, and agility is not ready
to ride this motorcycle.
Motorcycle Safety
5
Important Message to Parents
MENTAL AND EMOTIONAL MATURITY
are requirements for safe riding. Does your
youngster think through problems and come to
logical solutions? On a bicycle, does your
youngster obey safe riding rules? Be honest!
Young people who take unnecessary risks,
make bad judgments, and don’t obey rules are
not ready to ride this motorcycle.
Instruction and Supervision
If you decide that your youngster is ready to
safely operate this motorcycle, make sure both
of you carefully read and understand the
owner’s manual before riding. Also be sure that
your youngster has a helmet and other
appropriate riding equipment, and always
wears it when operating the vehicle or sitting
on it.
6
Motorcycle Safety
GOOD INSTRUCTION is an important part of
hands-on training. The teacher can either be
you or another responsible adult who has
experience with off-road motorcycle riding.
(For help in finding a qualified instructor, talk
with your dealer.) Even if you’re not the main
teacher, it’s up to you to ensure your
youngster’s safety. Remember, learning to ride
a motorcycle is a gradual, step-by-step process.
It takes time, patience, and practice–many
hours over a period of weeks or months.
SUPERVISION is another important obligation
of parents. Even after youngsters have become
skilled off-road riders, they should always ride
with adult supervision. It helps to regularly
remind young riders of basic safety rules and
precautions. And remember, it’s your
responsibility to see that the motorcycle is
properly maintained and kept in safe operating
condition.
SAFE AND RESPONSIBLE RIDING must be
an on-going commitment – by you and your
youngster. When you both put safety first, you
can enjoy more peace of mind, and your
youngster can enjoy more hours of safe offroad riding.
For your convenience, this CRF125F/FB
comes with an ignition switch and key. Remove
the key when the motorcycle is parked to help
prevent unauthorized use.

Loading, Accessories & Modifications
Your Honda was designed as a rider-only
motorcycle. It was not designed to carry a
passenger or cargo. A passenger or cargo could
interfere with your ability to move around to
maintain your balance and control of the
motorcycle.
In addition, exceeding the weight limits or
carrying an unbalanced load can seriously
affect your motorcycle’s handling, braking, and
stability. Adding accessories or making
modifications that change this motorcycle’s
design and performance can also make it
unsafe. Also, the weight of any accessories will
reduce the maximum load the motorcycle can
carry.
8
Motorcycle Safety
More specific information on load limits,
accessories, and modifications follows.
Loading
How much weight you put on your motorcycle,
and how you load it, are important to your safety.
If you decide to carry cargo, you should be aware
of the following information.
Overloading or carrying a passenger
can cause a crash and you can be
seriously hurt or killed.
Follow all load limits and other loading
guidelines in this manual.
Loading, Accessories & Modifications
Load Limits
Following are the load limits for your
motorcycle:
Maximum weight capacity
CRF125F: 176 lb (80 kg)
CRF125FB: 194 lb (88 kg)
Includes the weight of the rider and any
accessories.
Loading Guidelines
As discussed on page 8, we recommend that
you do not carry any cargo on this motorcycle.
However, if you decide to carry cargo, ride at
reduced speeds and follow these commonsense guidelines:
• Keep cargo small and light. Make sure it
cannot easily be caught on brush or other
objects, and that it does not interfere with
your ability to shift position to maintain
balance and stability.
• Place weight as close to the center of the
motorcycle as possible.
• Do not attach large or heavy items (such as a
sleeping bag or tent) to the handlebar, fork,
or front fender.
• Make sure that all cargo is tied down
securely.
• Never exceed the maximum weight limit.
• Check that both tires are inflated properly.

Loading, Accessories & Modifications
Accessories & Modifications
Modifying your motorcycle or using nonHonda accessories can make your motorcycle
unsafe.
Before you consider making any modifications
or adding an accessory, be sure to read the
following information.
Improper accessories or modifications
can cause a crash in which you can be
seriously hurt or killed.
Follow all instructions in this owner’s
manual regarding modifications and
accessories.
10
Motorcycle Safety
Accessories
We strongly recommend that you use only
Honda Genuine Accessories that have been
specifically designed or approved and tested for
your motorcycle. Because Honda cannot test all
other accessories, you must be personally
responsible for proper selection, installation,
and use of non-Honda accessories. Check with
your dealer for assistance and always follow
this guideline:
• Make sure the accessory does not reduce
ground clearance and lean angle, limit
suspension travel or steering travel, alter
your riding position, or interfere with
operating any controls.
Loading, Accessories & Modifications
Modifications
We strongly advise you not to remove any
original equipment or modify your motorcycle
in any way that would change its design or
operation. Such changes could seriously impair
your motorcycle’s handling, stability, and
braking, making it unsafe to ride.
We also advise you not to make any
modifications or remove any equipment (such
as the USDA qualified spark arrester or
emission control system components) that
would make the motorcycle illegal in your area.

Safety Labels
(For USA)
(For Canada)
This page shows the locations of safety labels on your motorcycle. Some labels warn you of
potential hazards that could cause serious injury. Others provide important safety information. Read
these labels carefully and don’t remove them.
If a label comes off or becomes hard to read, contact your dealer for a replacement.

23
Are You Ready to Ride?
Before you ride your motorcycle for the first
time, we strongly recommend that you:
• read this owner’s manual
• make sure you understand all the safety
messages
• know how to operate all the controls
Before each ride, we also suggest that you
make sure you:
• are in good physical and mental condition
• are free of alcohol and drugs
• are wearing an approved motorcycle helmet
(with chin strap tightened securely), eye
protection, and other protective clothing
24
Before Riding
Protective Apparel
For your safety, we strongly recommend that
you always wear an approved motorcycle
helmet, eye protection, boots, gloves, long
pants, and a long-sleeved jersey, shirt, or jacket
whenever you ride. Although complete
protection is not possible, wearing the proper
gear can reduce the chance of injury when you
ride. Following are suggestions to help you
choose the proper gear.
Not wearing a helmet increases the
chance of serious injury or death in a
crash.
Be sure you always wear a helmet, eye
protection and other protective apparel
when you ride.
Helmets and Eye Protection
Your helmet is your most important piece of
riding gear because it offers the best protection
against head injuries. A helmet should fit your
head comfortably and have a chin strap that can
be tightened securely.
An open-face helmet offers some protection,
but a full-face helmet offers more. Regardless
of the style, look for a DOT (Department of
Are You Ready to Ride?
Transportation) sticker on any helmet you buy
(USA only). Always wear a face shield or
goggles to protect your eyes and help your
vision.
Additional Riding Gear
In addition to a helmet and eye protection, we
also recommend:
• Sturdy off-road motorcycle boots to help
protect your feet, ankles, and lower legs.
• Off-road motorcycle gloves to help protect
your hands.
• Riding pants with knee and hip pads, a riding
jersey with padded elbows, and a chest/
shoulder protector.
Before Riding
25
Is Your Motorcycle Ready to Ride?
Before each ride, it’s important to inspect your
motorcycle and make sure any problem you
find is corrected. A pre-ride inspection is a
must because off-road riding can be tough on a
motorcycle and you don’t want to have a
breakdown far from help.
Improperly maintaining this motorcycle
or failing to correct a problem before
riding can cause a crash in which you
can be seriously hurt or killed.
Always perform a pre-ride inspection
before every ride and correct any
problems.
26
Before Riding
Note to Parents:
If a youngster will be performing any of the
following pre-ride inspection procedures, it’s
your responsibility to provide careful
supervision and make sure they are performed
safely.

attempts, it may be flooded with excess fuel.
To clear a flooded engine:
Using The Start Button
1. Push the choke lever down all the way to
OFF.
2. Open the throttle fully.
3. While pushing the engine stop button, press
the start button for 5 seconds.
4. Release the engine stop button.
5. Follow the High Air Temperature starting
procedure (page 33).

Basic Operation & Riding
Using The Kickstarter
1. Push the choke lever down all the way to
OFF.
2. Open the throttle fully.
3. While pushing the engine stop button, crank
the engine several times with the kickstarter.
4. Release the engine stop button.
5. Follow the High Air Temperature starting
procedure (page 33).
How to Stop the Engine
To stop the engine, shift into neutral, push the
engine stop button in, and hold it in until the
engine stops.
Your motorcycle has four forward gears.
To start riding, after the engine has been
warmed and the side stand raised:
1. Close the throttle and pull the front brake
lever in.
2. Pull the clutch lever all the way in.
Shifting Gears
3. Depress the shift lever from neutral down to
first gear.
4. Release the front brake. Gradually open the
throttle while you slowly release the clutch
lever.
If engine rpm (speed) is too low when you
release the clutch lever, the engine will stall.
If engine rpm is too high or you release the
clutch lever too quickly, your motorcycle
may lurch forward.
5. When you attain a moderate speed, close the
throttle, pull the clutch lever in, and raise the
shift lever. After shifting, release the clutch
lever and apply the throttle.

throttle, pull the clutch lever in, and depress
the shift lever. After shifting, release the
clutch lever and apply the throttle.
Basic Operation & Riding
Learning when to shift gears comes with
experience. Upshift to a higher gear or reduce
throttle before engine rpm (speed) gets too
high. Downshift to a lower gear before you feel
the engine laboring (lugging) at low rpm.
Downshifting can help slow your motorcycle,
especially on downhills. However, downshifting
when engine rpm is too high can cause engine
damage.
To prevent transmission damage, do not coast
or tow the motorcycle for long distances with
the engine off.
Braking
To slow or stop, apply the front brake and rear
brake smoothly, while downshifting to match
your speed. Gradually increase braking as you
feel the brakes slowing your speed. To prevent
stalling the engine, pull the clutch lever in
before coming to a complete stop. For support,
put your left foot down first, then your right
foot when you have finished using the rear
brake.
For maximum braking, close the throttle and
firmly apply the brake lever and pedal controls.
Applying the brakes too hard may cause the
wheels to lock and slide, reducing control of
your motorcycle. If this happens, release the
brake controls, steer straight ahead until you
regain control, then reapply the brakes more
gently.
Generally, reduce your speed or complete
braking before beginning a turn. Avoid braking
or closing the throttle quickly while turning.
Either action may cause one or both wheels to
slip. Any wheel slip will reduce your control of
your motorcycle.
When riding in wet or rainy conditions, or on
loose surfaces, the ability to maneuver and stop
will be reduced. All of your actions should be
smooth under these conditions. Rapid
acceleration, braking or turning may cause loss
of control. For your safety, exercise extreme
caution when braking, accelerating, or turning.
Basic Operation & Riding
37
Braking
When descending a long, steep grade, use
engine compression braking by downshifting,
with intermittent use of both brakes.
When you brake to a stop, pull the clutch lever
in before stopping completely to prevent
stalling the engine. For support, put your left
foot on the ground first, then your right foot
when you have finished braking.
38
Basic Operation & Riding
Lower the side stand to support your
motorcycle. Turn the ignition switch OFF and
remove the key. If you’re finished riding for the
day, also turn the fuel valve OFF. Always
choose a level place to park.

The Importance of Maintenance
A well-maintained motorcycle is essential for
safe, economical, and trouble-free riding. It
will also help reduce air pollution. Careful
preride inspections and good maintenance are
especially important because your motorcycle
is designed to be ridden over rough off-road
terrain.
To help you properly care for your motorcycle,
this section of the manual provides a
Maintenance Schedule. The service intervals in
this schedule are based on average riding
conditions.
More frequent service is needed if you subject
your motorcycle to severe use (such as
competition) or ride in unusually wet or dusty
areas.
Frequent servicing of the air cleaner is
especially important to help you avoid a
possible costly engine repair.
If your motorcycle overturns or is involved in a
crash, be sure your dealer inspects all major
parts, even if you are able to make some repairs.
Improperly maintaining this motorcycle
or failing to correct a problem before
you ride can cause a crash in which
you can be seriously hurt or killed.
Always follow the inspection and
maintenance recommendations and
schedules in this owner’s manual.

Note to Parents:
As a parent, it’s up to you to make sure that this
motorcycle is properly maintained and kept in
safe operating condition. For youngsters,
learning how to take care of a motorcycle and
perform basic maintenance can be an
important part of their riding experience.
However, if you allow a youngster to perform
or assist in any maintenance task, such as
filling the tank with gasoline, you should
provide close supervision to make sure that it is
performed safely.
Maintenance Safety
The maintenance section includes instructions
on how to perform some important
maintenance tasks. Some of the most important
safety precautions follow. However, we cannot
warn you of every conceivable hazard that can
arise in performing maintenance. Only you can
decide whether or not you should perform a
given task.
Failure to properly follow maintenance
instructions and precautions can cause
you to be seriously hurt or killed.
Always follow the procedures and
precautions in this owner’s manual.
Important Safety Precautions
• Make sure the engine is off before you begin
any maintenance or repairs.
This will help eliminate several potential
hazards:
Carbon monoxide poisoning from engine
exhaust. Be sure there is adequate
ventilation whenever you operate the engine.
Burns from hot motorcycle parts. Let the
engine and exhaust system cool before
touching.
Injury from moving parts. Do not run the
engine unless instructed to do so.

Servicing Your Honda
45
Maintenance Safety
• Read the instructions before you begin, and
make sure you have the tools and skills
required.
• To help prevent the motorcycle from falling
over, park it on a firm, level surface, using
the side stand or a maintenance stand to
provide support.
• To reduce the possibility of a fire or
explosion, be careful when working around
gasoline. Use only a non-flammable (high
flash point) solvent such as kerosene–not
gasoline–to clean parts. Keep cigarettes,
sparks, and flames away from all fuel related
parts.

Maintenance Schedule
To maintain the safety and reliability of your
motorcycle, regular inspection and service is
required as shown in the Maintenance Schedule
that follows.
The Maintenance Schedule lists items that can
be performed with basic mechanical skills and
hand tools. Procedures for these items are
provided in this manual.
The Maintenance Schedule also includes
items that involve more extensive procedures
and may require special training, tools, and
equipment. Therefore, we recommend that
you have your dealer perform these tasks
unless you have advanced mechanical skills
and the required tools. Procedures for items
in this schedule are provided in a service
manual available for purchase from your
dealer (page 160).
Because your motorcycle does not have an
odometer, service intervals in the maintenance
schedules are expressed in terms of riding days
as well as miles. To avoid overlooking required
service, we urge you to develop a convenient
way to record the number of days and/or miles
you ride.
If you do not feel capable of performing a given
task or need assistance, remember that your
Honda dealer knows your motorcycle best and
is fully equipped to maintain and repair it.
If you decide to do your own maintenance, use
only Honda Genuine Parts or their equivalents
for repair or replacement to ensure the best
quality and reliability.

Fuel
Refer to Safety Precautions on page 45.
Fuel Recommendation
Type unleaded
Pump Octane Number 86 (or higher)
Your engine is designed to use any unleaded
gasoline that has a pump octane number of 86
or higher. Gasoline pumps at service stations
normally display the pump octane number. For
information on the use of oxygenated fuels, see
page 156.
Use of lower octane gasoline can cause
persistent ‘‘pinging’’ or ‘‘spark knock’’ (a
louder rapping noise) which, if severe, can lead
to engine damage. (Light pinging experienced
while operating under a heavy load, such as
climbing a hill, is no cause for concern.)
58
Servicing Your Honda
If pinging or spark knock occurs at a steady
engine speed under normal load, change brands
of gasoline. If pinging or spark knock persists,
consult your dealer.
Use only unleaded fuel in your Honda. If you
ride your Honda in a country where leaded fuel
might be available, take precautions to use only
unleaded fuel.
Never use stale or contaminated gasoline or an
oil/gasoline mixture. Avoid getting dirt, dust, or
water in the fuel tank.

Air Cleaner
Proper air cleaner maintenance is very
important for off-road vehicles. A dirty, watersoaked, worn-out, or defective air cleaner will
allow dirt, dust, mud, and other impurities to
pass into the engine.
Service the air cleaner more frequently if you
ride in unusually wet or dusty areas. Your
dealer can help you determine the correct
service interval for your riding conditions.
Your motorcycle’s air cleaner has very specific
performance requirements. Use a new Honda
Genuine air cleaner specified for your model or
an air cleaner of equal quality.
Using the wrong air cleaner may result in
premature engine wear.
Proper air cleaner maintenance can prevent
premature engine wear or damage, expensive
repairs, low engine power, poor gas mileage,
and spark plug fouling.
Improper or lack of proper air cleaner
maintenance can cause poor performance and
premature engine wear.

The front brake is the hydraulic disc type. As
the brake pads wear, the brake fluid level will
drop. A leak in the system will also cause the
level to drop.
Frequently inspect the system to ensure there
are no fluid leaks. Periodically inspect the
brake fluid level and the brake pads for wear.
If the front brake lever freeplay does not feel
within the normal range while riding, check the
brake pads. If they are not worn beyond the
recommended limit (page 88), there is probably
air in the brake system. See your dealer to have
the air bled from the system.
