Safety Guidelines
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 helmet and protective
apparel. 2 P. 8
Before Riding
Make sure that you are physically fit, mentally
focused and free of alcohol and drugs. Check
that you are wearing an approved helmet and
protective apparel.
Take Time to Learn & Practice
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.

Safety Guidelines
Ride Defensively
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 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
judgment 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
4
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 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. 13), and do not modify
your vehicle or install accessories that would
make your vehicle unsafe (2 P. 12).
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.
Page 9
Safety Guidelines
If you decide to continue riding, first turn the
ignition switch to the OFF position, and evaluate
the condition of your vehicle. Inspect for fluid
leaks, check the tightness of critical nuts and
bolts, and check the handlebar
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.
, control levers,
Carbon Monoxide Hazard
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.
3WARNING
Running the engine of your vehicle
while in an enclosed or even partially
enclosed area can cause a rapid buildup of toxic carbon monoxide gas.
Breathing this colorless, odorless gas
can quickly cause unconsciousness and
lead to death.
Only run your vehicle's engine when it
is located in a well ventilated area
outdoors.

Riding Precautions
Riding Precautions
Break-in Period
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.
Brakes
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.

Riding Precautions
Anti-lock Brake System (ABS) on Front
#
Vehicle Safety
Wheel
Monkey125A only
This model equipped with an Anti-lock Brake
System (ABS) designed to help prevent the front
brake from locking up during hard braking.
● There is no ABS function to the rear wheel.
● ABS does not reduce braking distance. In
certain circumstances, ABS may result in a
longer stopping distance.
● ABS does not function at speeds below 6
mph (10 km/h).
● The brake lever may recoil slightly when
applying the brakes. This is normal.
● Always use the recommended front/rear
tires and sprockets to ensure correct ABS
operation.
10
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.
Page 15
Parking
● 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 handlebar and remove the key when
leaving the vehicle 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 vehicle to the left until its
weight rests on the side stand.
Riding Precautions
4.
Turn the handlebar fully to the left.
u Turning the handlebar to the right
reduces stability and may cause the
vehicle to fall.
5.
Turn the ignition switch to the LOCK
position and remove the key. 2 P. 24
Refueling and Fuel Guidelines
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. 2 P. 111
● Do not use stale or contaminated gasoline
or an oil/gasoline mixture.
● Avoid getting dirt or water in the fuel tank.
