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.
2 P. 6
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 grab rail or your waist, leaning with you in
turns, and keeping their feet on the footpegs,
even when the scooter is stopped.
Take Time to Learn & Practice
Even if you have ridden other scooters, practice
riding in a safe area to become familiar with how
this scooter works and handles, and to become
accustomed to the scooter’s size and weight.
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.

Safety Guidelines
Scooter Safety
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 scooter properly
maintained and in safe riding condition.
Inspect your scooter before every ride and
perform all recommended maintenance. Never
exceed load limits (
your scooter or install accessories that would
make your scooter unsafe (
2 P. 11), and do not modify
2 P. 10).
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

can quickly cause unconsciousness and
lead to death.
Only run your scooter's engine when it is
located in a well ventilated area
outdoors.
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 scooter inside a garage or other

Riding Precautions
Running-in Period
During the first 500 km (300 miles) of running,
follow these guidelines to ensure your scooter’s
future reliability and performance.
● Avoid full-throttle starts and rapid
acceleration.
● Avoid hard braking.
● Ride conservatively.
Brakes
Observe the following guidelines:
● Avoid excessively hard braking.
u Sudden braking can reduce the scooter’s
stability.
u Where possible, reduce speed before
turning; otherwise you risk sliding out.
● Exercise caution on low traction surfaces.
u The tyres 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.
● For full brake effectiveness, operate both the
front and rear brakes together.
Combi Brake
#
Your scooter is equipped with a brake system
that distributes the braking force between the
front and rear brakes.
The distribution of the braking force applied to
the front and rear brakes when operating the
front brake lever only and when operating the
rear brake lever only is different.
For full braking effectiveness, operate both the
front and rear brakes together.

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.
Parking
● Park on a firm, level surface.
● If you must park on a slight incline or loose
surface, park so that the scooter 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 and close
the shutter when leaving the scooter
unattended.
Use of an anti-theft device is also
recommended.
Also set the anti-theft alarm system.

Importance of Maintenance
Keeping your scooter well-maintained is
absolutely essential to your safety and to protect
your investment, obtain maximum performance,
avoid breakdowns, and reduce air pollution.
Maintenance is the owner’s responsibility. Be
sure to inspect your scooter before each ride,
and perform the periodic checks specified in the
Maintenance Schedule.
Improperly maintaining your scooter 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

Maintenance Safety
Always read the maintenance instructions before
you begin each task, and make sure that you
have the tools, parts, and skills required. 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.
Follow these guidelines when performing
maintenance.
● Stop the engine and remove the key.
● Place your scooter on a firm, level surface
using the side stand, centre stand or a
maintenance stand to provide support.
● Allow the engine, muffler, brakes, and other
high-temperature parts to cool before
servicing as you can get burned.
● Run the engine only when instructed, and do
so in a well-ventilated area.
Maintenance
Maintenance Schedule
The maintenance schedule specifies the
maintenance requirements necessary to
ensure safe, dependable performance, and
proper emission control.
Maintenance work should be performed in
accordance with Honda’s standards and
specifications by properly trained and
equipped technicians. Your dealer meets all of
these requirements. Keep an accurate record
of maintenance to help ensure that your
scooter is properly maintained. Make sure that
whomever performs the maintenance
completes this record.
All scheduled maintenance is considered a
normal owner operating cost and will be
charged to you by your dealer. Retain all
receipts. If you sell the scooter, these receipts
should be transferred with the scooter to the
new owner.
Honda recommends that your dealer should
road test your scooter after each periodic
maintenance is carried out.
