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, in this owner's manual and
competition handbook. 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:
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
provided under the following titles:

Safety Guidelines
Follow these guidelines to enhance your safety:
● Perform all routine and regular inspections
specified in this owner's manual and
competition handbook.
● 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. 7
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 Get to Know Your Vehicle
Because every motorcycle is unique, take time
to become thoroughly familiar with how this
one operates and responds to your commands
before placing your machine, and yourself, in
competition.
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.
Never Carry a Passenger
There are no handholds, seat, or footrests to
carry a passenger.
Safety Guidelines
Vehicle Safety

Continued
Don't Drink or Use Drugs and Ride
Alcohol or drugs 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. The same is true for drug use. Don't drink
or use and ride, and don't let your friends do it
either.
Keep Your Honda in Safe Condition
Maintaining your vehicle properly is critical to
your safety. A loose bolt, for example, can cause
a breakdown in which you can be seriously
injured.
Lithium-Ion (Li-Ion) Battery
If you smell an unusual odor coming from the
lithium-ion (li-ion) battery, park your vehicle in a
safe place outside and away from flammable
objects, then stop the engine. Have your vehicle
inspected by your dealer immediately.
Safety Guidelines

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 build-
up 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.

Maintenance Fundamentals
Pre-ride Inspection
To ensure safety, it is your responsibility to
perform a pre-ride inspection and make sure
that any problem you find is corrected. A pre-
ride inspection is a must, not only for safety, but
because having a breakdown, or even a flat tire,
can be a major inconvenience.
Refer to Competition Handbook for procedures.
Competitive riding can be tough on a
motorcycle, so it’s important to inspect your
vehicle and correct any problems you find
before each ride.
Check the following before each ride:
●
Engine oil level.
●
Fuel line for condition.
●
Coolant for proper level.
●
Cooling system and hoses for condition.
● Spark plug for proper heat range, carbon
fouling and spark plug wire terminal for
looseness.
●
Air cleaner for condition and contamination.
● Clutch lever freeplay.
● Breather drain for cleaning.
●
Steering head bearing and related parts for
condition.
● Throttle operation.
●
Tires for damage or improper inflation pressure.
●
Spokes for looseness.
●
Rim locks for looseness.
●
Front and rear suspension for proper operation.
●
Front and rear brakes, check operation.
● Drive chain for correct slack and adequate
lubrication.
● Drive chain sliders and drive chain rollers for
damage or wear.
● Exhaust pipe/Muffler for looseness.
●
Every possible part for looseness (such as
cylinder head bolts, engine mounting bolts/
nuts, axle nuts, handlebar holder bolts, fork
bridge pinch bolts, drive chain adjuster, lock
nuts, drive chain roller bolt/nut, wire harness
connectors).
●

• After adjustment, check that the chain
adjuster index marks are in the same
position on each side. This will ensure that
the rear wheel is in proper alignment and
allow maximum performance from the rear
disc brake.
Maintaining proper wheel alignment will also
extend brake pad lifespan.
• Suspend the front wheel above the ground

After Competition Maintenance
It is important to the long term performance of
your vehicle to practice a consistent
maintenance program. Right after the event is a
good time to begin your next maintenance
cycle.
#
After Race (CRF250RX)/Moto (CRF250R)
Lubrication
Apply a light coating of rust-inhibiting oil to the
drive sprocket and any steel portions of the
chassis or engine where the paint has worn
away.
This will prevent rusting of the exposed metal.
Apply rust-inhibiting oil more heavily if the
event was particularly wet or muddy. Take care
to avoid spraying any oil near the brake pads or
the brake discs.
Take care to prevent catching your fingers
between the chain and sprocket.
Remove the drive chain, clean and lubricate it.
Be sure the chain is wiped clean and is dry
before lubricating the chain.
#
Routine Cleaning
If your vehicle is only slightly dirty, it is best to

Continued
Take care to prevent catching your fingers
between the chain and sprocket.
A variety of reasonably priced cleaning brushes
are available from variety, drug, food, and
hardware stores. Some of these brushes are
extremely useful in removing dirt from the many
tight contours of the metal pieces of your
vehicle.
Avoid using stiff, abrasive brushes on the plastic
or rubber parts.
If your vehicle was exposed to sea air or salt
water, rinse it as soon as possible after the
event, dry it, and apply a spray lubricant to all
metal parts.
If you decide to wash your vehicle or use
cleaners, refer to "Caring for Your Vehicle".

particular riding condition, make changes a little
at a time.
#
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.
#
Inspecting for Abnormal Wear
Inspect the tires for signs of abnormal wear on
the contact surface.
#
Inspecting Rims and Valve Stems
Inspect the rims for damage and loose spokes.
Also inspect the valve stems for their positions.
A tilted valve stem indicates the tube is slipping
inside the tire or the tire is slipping on the rim.
See your dealer.
3WARNING
Riding on tires that are excessively worn
or improperly inflated can cause a crash
in which you can be seriously hurt or
killed.

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.
While you're cleaning, be sure to look for
damage, wear, and gasoline or oil leaks.
Washing
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 plastic components with extra
care to avoid scratching them.
Avoid directing water into the air cleaner,
muffler, and electrical parts.
u Do not use steel wool to clean the frame
as it could damage or discolor the frame
surface. Scotch Brite Hand Pad #7447-
maroon is for removing stains on the
non-coated aluminum frame only.
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.
Lubricate the drive chain immediately after
washing and drying the vehicle.
6.
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.

Transporting Your Vehicle
If your vehicle needs to be transported, it
should be carried on a motorcycle trailer or a
flatbed truck or trailer that has a loading ramp
or lifting platform, and motorcycle tie-down
straps. Never try to tow your vehicle with a
wheel or wheels on the ground.
NOTICE
Towing your vehicle can cause serious damage
to the transmission.
Transporting Your Vehicle
Information
62
If you use a truck or motorcycle trailer to
transport your vehicle, we recommend that you
follow these guidelines:
● Use a loading ramp.
● Relieve the fuel pressure and drain the fuel
from the fuel tank into an approved gasoline
container.
● Secure the vehicle in an upright position,
using motorcycle tie-down straps. Avoid
using rope, which can loosen and allow the
vehicle to fall over.
To secure your vehicle, brace the front wheel
against the front of the truck bed or trailer rail.
Attach the lower ends of two straps to the tie-
down hooks on truck bed or trailer rail. Attach
the upper ends of the straps to the handlebar
(one on the right side, the other on the left),
close to the fork.
Check that the tie-down straps do not contact
any control cables or electrical wiring.
Tighten both straps until the front suspension is
compressed about half-way. Too much pressure
is unnecessary and could damage the fork seals.
Use another tie-down strap to keep the rear of
the vehicle from moving.
We recommend that you do not transport your
vehicle on its side. This can damage the vehicle,
and leaking gasoline could be a hazard.
Transporting Your Vehicle
Information
63
You & the Environment
Owning and riding a vehicle can be enjoyable,
but you must do your part to protect the
environment.
Choose Sensible Cleaners
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.
Recycle Wastes
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.

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 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.
●
Do not use gasoline containing methanol
(methyl alcohol).
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.
NOTICE
Improper use of oxygenated fuels can damage
metal, rubber, and plastic parts of your fuel
system.
Oxygenated fuel can also damage paint.
If you notice any undesirable operating
symptoms or performance problems, try a
different brand of gasoline.
