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 inexhaust gases is toxic and can kill you.

Always Wear a HelmetIt's a proven fact: helmets and protectiveapparel significantly reduce the number andseverity of head and other injuries. So alwayswear an approved helmet and protectiveapparel. 2 P. 8

Before RidingMake sure that you are physically fit, mentallyfocused and free of alcohol and drugs. Checkthat you are wearing an approved helmet andprotective apparel.

Take Time to Learn & PracticeEven if you have ridden other vehicles, practiceriding in a safe area to become familiar withhow this vehicle works and handles, and tobecome accustomed to the vehicle's size andweight.

We recommend that all riders take a certifiedcourse approved by the Motorcycle SafetyFoundation (MSF). New riders should start withthe basic course, and even experienced riderswill find the advanced course beneficial.For information about the MSF training coursenearest you, call the national toll-free number:(800) 446-9227.

Ride DefensivelyAlways pay attention to other vehicles aroundyou, and do not assume that other drivers seeyou. Be prepared to stop quickly or perform anevasive maneuver.

Make Yourself Easy to SeeMake yourself more visible, especially at night,by wearing bright reflective clothing, positioningyourself so other drivers can see you, signalingbefore turning or changing lanes, and usingyour horn when necessary.

Ride within Your LimitsNever ride beyond your personal abilities orfaster than conditions warrant. Fatigue andinattention can impair your ability to use goodjudgment and ride safely.

Don't Drink and RideAlcohol and riding don't mix. Even one alcoholicdrink can reduce your ability to respond to

changing conditions, and your reaction timegets worse with every additional drink. Don'tdrink and ride, and don't let your friends drinkand ride either.

Keep Your Honda in Safe ConditionIt's important to keep your vehicle properlymaintained and in safe riding condition.Inspect your vehicle before every ride andperform all recommended maintenance. Neverexceed load limits (2 P. 13), and do not modifyyour vehicle or install accessories that wouldmake your vehicle unsafe (2 P. 12).

If You are Involved in a CrashPersonal safety is your first priority. If you oranyone else has been injured, take time toassess the severity of the injuries and whether itis safe to continue riding. Call for emergencyassistance if needed. Also follow applicable lawsand regulations if another person or vehicle isinvolved in the crash.

If you decide to continue riding, first turn theignition switch to the OFF position, and evaluatethe condition of your vehicle. Inspect for fluidleaks, check the tightness of critical nuts andbolts, and check the handlebar, control levers,brakes, and wheels. Ride slowly and cautiously.Your vehicle may have suffered damage that isnot immediately apparent. Have your vehiclethoroughly checked at a qualified service facilityas soon as possible.

Carbon Monoxide HazardExhaust contains poisonous carbon monoxide, acolorless, odorless gas. Breathing carbonmonoxide can cause loss of consciousness andmay lead to death.

If you run the engine in confined or even partlyenclosed area, the air you breathe couldcontain a dangerous amount of carbonmonoxide.Never run your vehicle inside a garage or otherenclosure.

3WARNINGRunning the engine of your vehiclewhile in an enclosed or even partiallyenclosed area can cause a rapid build-up of toxic carbon monoxide gas.

Breathing this colorless, odorless gascan quickly cause unconsciousness andlead to death.

Riding PrecautionsBreak-in Period

During the first 300 miles (500 km) of running,follow these guidelines to ensure your vehicle'sfuture reliability and performance.● Avoid full-throttle starts and rapid

acceleration.● Avoid hard braking and rapid down-shifts.● Ride conservatively.

BrakesObserve 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 arelonger.

● Avoid continuous braking.u Repeated braking, such as when

descending long, steep slopes canseriously overheat the brakes, reducingtheir effectiveness. Use engine brakingwith intermittent use of the brakes toreduce speed.

● For full braking effectiveness, operate boththe front and rear brakes together.


Riding PrecautionsVehicle Safety

9Continued

# Anti-lock Brake System (ABS) on FrontWheel

Monkey125A onlyThis model equipped with an Anti-lock BrakeSystem (ABS) designed to help prevent the frontbrake 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 alonger stopping distance.

● ABS does not function at speeds below 6mph (10 km/h).

● The brake lever may recoil slightly whenapplying the brakes. This is normal.

● Always use the recommended front/reartires and sprockets to ensure correct ABSoperation.

# Engine BrakingEngine braking helps slow your vehicle downwhen you release the throttle. For furtherslowing action, downshift to a lower gear. Useengine braking with intermittent use of thebrakes to reduce speed when descending long,steep slopes.

# Wet or Rainy ConditionsRoad surfaces are slippery when wet, and wetbrakes further reduce braking efficiency.Exercise extra caution when braking in wetconditions.If the brakes get wet, apply the brakes whileriding at low speed to help them dry.


Riding Precautions

Vehicle Safety

Parking● Park on a firm, level surface.● If you must park on a slight incline or loose

surface, park so that the vehicle cannotmove or fall over.

● Make sure that high-temperature partscannot come into contact with flammablematerials.

● Do not touch the engine, muffler, brakesand other high-temperature parts until theycool down.

● To reduce the likelihood of theft, always lockthe handlebar and remove the key whenleaving the vehicle unattended.Use of an anti-theft device is alsorecommended.

# Parking with the Side Stand1. 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.

4. Turn the handlebar fully to the left.u Turning the handlebar to the right

reduces stability and may cause thevehicle to fall.

5. Turn the ignition switch to the LOCKposition and remove the key. 2 P. 24

Refueling and Fuel GuidelinesFollow 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 indecreased engine performance.

● Do not use fuels containing a highconcentration of alcohol. 2 P. 111

● Do not use stale or contaminated gasolineor an oil/gasoline mixture.

● Avoid getting dirt or water in the fuel tank.

Noise Emission RequirementsThe EPA requires that vehicles built afterJanuary 1, 1983 comply with applicable noiseemission standards for one year or 3,730 miles(6,000 km) after the time of purchase whenoperated and maintained according to theinstructions provided.

Exhaust Emission Control SystemThe exhaust emission control system includesthe following components that should not needadjustment, although periodic inspection byyour dealer is recommended.

# PGM-FI SystemThe PGM-FI (programmed fuel injection) systemuses sequential multiport fuel injection, and iscomprised of air intake, engine control, fuelcontrol, and exhaust control subsystems. Theengine control module (ECM) uses sensors todetermine how much air enters the engine, andthen controls how much fuel to inject.

# Ignition Timing Control SystemThe ignition timing control system adjusts theignition timing to reduce the amount of HC,CO, and NOx produced.

# Catalytic ConvertersThe exhaust system contains one or morecatalytic converters. Catalytic converters use acatalyst to convert most of the harmful exhaustgas compounds into harmless compounds.

Evaporative Emission Control System50 STATE (meets California)An evaporative emissions control system uses acanister filled with charcoal to adsorb fuel vaporfrom the fuel tank while the engine is off. Thevapor is drawn into the engine and burnedwhile riding.
