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 motorcycle helmet andprotective apparel. 2 P. 9

Before RidingMake sure that you are physically fit, mentallyfocused and free of alcohol and drugs. Checkthat you and your passenger are both wearingan approved motorcycle helmet and protectiveapparel. Instruct your passenger on holdingonto the seat strap or your waist, leaning withyou in turns, and keeping their feet on thefootpegs, even when the motorcycle is stopped.

Take Time to Learn & PracticeEven if you have ridden other motorcycles,practice riding in a safe area to become familiarwith how this motorcycle works and handles,and to become accustomed to the motorcycle'ssize and weight.

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.

USA Other riding tips can be found in the Youand Your Motorcycle Riding Tips booklet thatcame with your motorcycle.

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

Riding PrecautionsBreak-in Period

During the first 300 miles (500 km) of running,follow these guidelines to ensure yourmotorcycle's future 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

motorcycle's stability.u Where possible, reduce speed before

turning; otherwise you risk sliding out.

Riding Precautions

Motorcycle Safety

10

● 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.

# Anti-lock Brake System (ABS) on FrontWheel

GROM125A 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. Incertain circumstances, ABS may result in alonger stopping distance.

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

● The brake lever and pedal may recoil slightlywhen applying the brakes. This is normal.

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

# Engine BrakingEngine braking helps slow your motorcycledown when 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.

Riding PrecautionsM

otorcycle Safety

11Continued

# 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.

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

surface, park so that the motorcycle 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 motorcycle unattended.Use of an anti-theft device is alsorecommended.

Emission Control SystemsYour motorcycle engine emits combustionbyproducts, including carbon monoxide (CO),oxides of nitrogen (NOx), and hydrocarbons(HC). Gasoline evaporation also emitshydrocarbons. Controlling the production ofNOx, CO, and HC is important for theenvironment.

Exhaust Emission RequirementsThe U.S. Environmental Protection Agency(EPA), the California Air Resources Board(CARB), and Environment and Climate ChangeCanada (ECCC) require that your motorcyclecomply with applicable exhaust, crankcase, andfuel permeation emission standards during itsuseful life, when operated and maintainedaccording to the instructions provided.CARB also requires that your motorcyclecomply with applicable evaporative emissionrequirements during its useful life, when

operated and maintained according to theinstructions provided.USA Compliance with the terms of theDistributor's Warranties for Honda MotorcycleEmission Control Systems is necessary in orderto maintain a valid emissions system warranty.

Noise Emission RequirementsThe EPA requires that motorcycles 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.

# Secondary Air Injection SystemThe secondary air injection system adds filteredair into the exhaust gas to help improveemission control performance.

# 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.

Emission Control Systems

Information

104

Crankcase Emissions Control SystemThe engine is equipped with a closed crankcasesystem to prevent discharging crankcaseemissions into the atmosphere.Blow-by gas is returned to the combustionchamber through the air cleaner and the intakemanifold.

Fuel Permeation Emission ControlThe fuel tank, fuel hoses, and fuel vapor chargehoses use fuel permeation control technologiesto prevent fuel vapor emissions. Tampering withthese components to reduce or defeat theeffectiveness of the fuel permeationtechnologies is prohibited.

Catalytic ConverterThis motorcycle is equipped with a three-waycatalytic converter. The catalytic convertercontains precious metals that serve as catalystsin high temperature chemical reactions thatconvert hydrocarbons (HC), carbon monoxide(CO), and oxides of nitrogen (NOx) in theexhaust gasses into safe compounds.

A defective catalytic converter contributes to airpollution and can impair your engine'sperformance. A replacement unit must be anoriginal Honda part or equivalent.

Follow these guidelines to protect yourmotorcycle's catalytic converter.● Always use unleaded gasoline. Leaded

gasoline will damage the catalytic converter.● Keep the engine in good running condition.

A poorly running engine can cause thecatalytic converter to overheat causingdamage to the converter or the motorcycle.

● If your engine is misfiring, backfiring, stalling,or otherwise not running properly, stopriding and turn off the engine. Have yourmotorcycle serviced as soon as possible.

Oxygenated FuelsSome conventional fuels blended with alcoholor an ether compound are available in somelocales to help reduce emissions to meet cleanair standards. These gasolines are collectivelyreferred to as oxygenated fuels. If you plan touse oxygenated fuel, check that it is unleadedand meets the minimum octane rating andblend requirement.

The following fuel blends are EPA-approvedand have been approved for use in yourmotorcycle:● Ethanol (ethyl alcohol) up to 10% by volume.

u Gasoline containing ethanol may bemarketed under the name Gasohol.

● Methanol (methyl alcohol) up to 5% byvolume that contain cosolvents andcorrosion inhibitors to protect the fuelsystem. Never use a blend containing morethan 5%.

If you accidentally fill your fuel tank with anoxygenated fuel containing higher percentages,you may experience performance problems. Toresolve the problem, have your dealer drain thefuel tank and replace with the correct fuel. Fuelsystem or performance problems resulting fromthe use of an oxygenated fuel containing higherpercentages are not covered by your warranty.

NOTICEImproper use of oxygenated fuels can damagemetal, rubber, and plastic parts of your fuelsystem.Oxygenated fuel can also damage paint.Damage caused by spilled fuel is not covered bywarranty.
