Ride Off-Road Only Be Alert for Off-Road Hazards

Ride within Your LimitsTake Time to Learn and Practice

Motorcycle Safety


Tips & Practice Guidef or the Of f -Highway Motorcyclist

Your motorcycle is designed and manufacturedfor off-road use only. The tires are not madefor pavement, and the motorcycle does nothave turn signals and other features requiredfor use on public roads. If you need to cross apaved or public road, get off and walk yourmotorcycle across.

The terrain can present a variety of challengeswhen you ride off-road. Continually ‘‘read’’the terrain for unexpected turns, drop-offs,rocks, ruts, and other hazards. Always keepyour speed low enough to allow time to see andreact to hazards.

Pushing limits is another major cause ofmotorcycle accidents. Never ride beyond yourpersonal abilities or faster than conditionswarrant. Remember that alcohol, drugs, fatigue,and inattention can significantly reduce yourability to make good judgments and ride safely.

Developing off-road riding skills is a gradual,step-by-step process. Start by practicing at lowspeeds in a safe area and slowly build yourskills. Personal instruction from an experiencedrider can also be valuable.

If you need assistance, ask your dealer aboutriding groups in your area.

Also be sure to read thebooklet that

came with your motorcycle (USA only).

Don’t Drink and Ride

Keep Your Honda in Safe Condition


Motorcycle Safety

Alcohol and riding don’t mix. Even one drinkcan reduce your ability to respond to changingconditions, and your reaction time gets worsewith every additional drink. So don’t drink andride, and don’t let your friends drink and rideeither.

It’s important to keep your motorcycle properlymaintained and in safe riding condition.Having a breakdown can be difficult,especially if you are stranded off-road far fromyour base. To help avoid problems, inspectyour motorcycle before every ride and performall recommended maintenance.

Riding Readiness

Important Message to Parents

Your child’s safety is very important to Honda.That’s why we urge you to read this messagebefore you let any young person ride thismotorcycle. Off-road riding can be fun. But, aswith riding a bicycle, bad judgment can resultin injury, and we don’t want that to happen! Asa parent, you can help prevent accidents bymaking good decisions about if, when, andhow your youngster rides this motorcycle.

The first decision you’ll need to make iswhether your youngster is ready to ride. Ridingreadiness varies widely from one person toanother, and age and size are not the onlyfactors.

PHYSICAL ABILITY is an importantconsideration. For example, riders must be bigenough to hold the motorcycle up, get on, andcomfortably sit on the seat with both feettouching the ground. They should also be ableto easily reach and work the brakes, throttle,and all other controls.

ATHLETIC ABILITY is necessary for riding amotorcycle. Generally speaking, youryoungster should be good at riding a bicyclebefore getting on a motorcycle. Can youryoungster judge speeds and distances whileriding a bicycle and react with proper hand andfoot actions? Anyone who does not have goodcoordination, balance, and agility is not readyto ride this motorcycle.

6 Motorcycle Safety

Instruction and Supervision


MENTAL AND EMOTIONAL MATURITYare requirements for safe riding. Does youryoungster think through problems and come tological solutions? On a bicycle, does youryoungster obey safe riding rules? Be honest!Young people who take unnecessary risks,make bad judgments, and don’t obey rules arenot ready to ride this motorcycle.

If you decide that your youngster is ready tosafely operate this motorcycle, make sure bothof you carefully read and understand theowner’s manual before riding. Also be sure thatyour youngster has a helmet and otherappropriate riding equipment and always wearsit when operating the vehicle or sitting on it.

GOOD INSTRUCTION is an important part ofhands-on training. The teacher can either beyou or another responsible adult who hasexperience with off-road motorcycle riding.(For help in finding a qualified instructor, talkwith your Honda dealer.) Even if you’re not themain teacher, it’s up to you to ensure youryoungster’s safety. Remember, learning to ridea motorcycle is a gradual, step-by-step process.It takes time, patience, and practice manyhours over a period of weeks or months.

7Motorcycle Safety


SUPERVISION is another important obligationof parents. Even after youngsters have becomeskilled off-road riders, they should always ridewith adult supervision. It helps to regularlyremind young riders of basic safety rules andprecautions. And remember, it’s yourresponsibility to see that the motorcycle isproperly maintained and kept in safe operatingcondition.

SAFE AND RESPONSIBLE RIDING must bean on-going commitment by you and youryoungster. When you both put safety first, youcan enjoy more peace of mind, and youryoungster can enjoy more hours of safe off-road riding.

For your convenience, this comeswith an ignition switch and key. Remove thekey when the motorcycle is parked to helpprevent unauthorized use.

Shifting Gears


Learning when to shift gears comes withexperience. Upshift to a higher gear or reducethrottle before engine rpm (speed) gets too high.Downshift to a lower gear before you feel theengine laboring (lugging) at low rpm.

Downshifting can help slow your motorcycle,especially on downhills. However,downshifting when engine rpm is too high cancause engine damage.

To prevent transmission damage, do not coastor tow the motorcycle for long distances withthe engine off.

03/06/17 14:18:26 31GCF670_044

36

Braking


Generally, reduce your speed or completebraking before beginning a turn. Avoid brakingor closing the throttle quickly while turning.Either action may cause one or both wheels toslip. Any wheel slip will reduce your control ofyour motorcycle.

When riding in wet or raining conditions, or onloose surfaces, the ability to maneuver and stopwill be reduced. All of your actions should besmooth under these conditions. Rapidacceleration, braking, or turning may cause lossof control. For your safety, exercise extremecaution when braking, accelerating, or turning.

To slow or stop, apply the front brake and rearbrake pedal smoothly, while downshifting tomatch your speed. Gradually increase brakingas you feel the brakes slowing your speed. Forsupport, put your left foot down first, then yourright foot when you are through using the rearbrake.

For maximum braking, close the throttle andfirmly apply the brake lever and pedal controls.

Applying the brakes too hard may cause thewheels to lock and slide, reducing control ofyour motorcycle. If this happens, release thebrake controls, steer straight ahead until youregain control, then reapply the brakes moregently.

When descending a long, steep grade, useengine compression braking by downshifting,with intermittent use of both brakes.

Parking


Lower the side stand to support yourmotorcycle. Turn the ignition switch OFF andremove the key. If you’re through riding forthe day, also turn the fuel valve OFF. Alwayschoose a level place to park.

03/06/17 14:18:38 31GCF670_046

38

Post-ride Inspection


When you return home after riding, thoroughlyclean your motorcycle and remove any dirt,mud, brush, rocks or other objects you mayhave picked up along the way.

After cleaning, carefully inspect yourmotorcycle for leaks or damage.

Be sure to lubricate the drive chain (page )to prevent rusting.

Fuel Recommendation


Saf ety PrecautionsRefer to on page .

Your engine is designed to use any gasolinethat has a pump octane number of 86 or higher.Gasoline pumps at service stations normallydisplay the pump octane number. Forinformation on the use of oxygenated fuels, seepage .

Use of lower octane gasoline can causepersistent ‘‘pinging’’ or ‘‘spark knock’’ (alouder rapping noise) which, if severe, can leadto engine damage. (Light pinging experiencedwhile operating under a heavy load, such asclimbing a hill, is no cause for concern.)

If pinging or spark knock occurs at a steadyengine speed under normal load, change brandsof gasoline. If pinging or spark knock persists,consult your Honda dealer.

We recommend that you use unleaded fuelbecause it produces fewer engine deposits andextends the life of exhaust system components.

Never use stale or contaminated gasoline or anoil/gasoline mixture. Avoid getting dirt, dust,or water in the fuel tank.

The adjustment must be made when the pistonis at the top of the compression stroke whenboth the intake and exhaust valves are closed.This condition can be determined by movingthe rocker arms. If they are free, it is anindication that the valves are closed and that thepiston is on the compression stroke. If they aretight and the valves are open, rotate theflywheel 360° and realign the T mark to theindex mark.

Rotate the generator flywheelcounterclockwise until the T mark ( ) on theflywheel lines up with the index mark ( ) onthe crankcase. In this position, the pistonmay either be on the compression or exhauststroke.

Saf ety Precautions

To safely operate your motorcycle, the tiresmust be the proper type (off-road) and size, ingood condition with adequate tread, andcorrectly inflated.

Refer to on page .

The following pages give detailed informationon how and when to check your air pressure,how to inspect your tires for wear and damage,

and our recommendations on tire repair andreplacement.

Make sure the valve stem caps are secure. Ifnecessary, install a new cap.

Properly inflated tires provide the bestcombination of handling, tread life, and ridingcomfort. Generally, underinflated tires wearunevenly, adversely affect handling, and aremore likely to fail from being overheated.Underinflated tires can also cause wheeldamage in rocky terrain. Overinflated tiresmake your motorcycle ride more harshly, aremore prone to damage from surface hazards,and wear unevenly.

Use a replacement tube equivalent to theoriginal.

We recommend that tubes be replaced by yourHonda dealer. Replacing a tube requiresremoving and reinstalling the wheel. Any timea tube is replaced, carefully inspect the tire asdescribed on page .

Inspect carefully for bumps or bulges in theside of the tire or the tread. Replace any tirethat has a bump or bulge.Look closely for cuts, slits, or cracks in thetires. Replace a tire if you can see fabric orcord.Check for rocks or other objects embeddedin the tire or tread. Remove any objects.

Check the position of both valve stems. Atilted valve stem indicates the tube isslipping inside the tire or the tire is slippingon the rim. See your Honda dealer.

Measure tread depth ( ). Replace the tirebefore depth at the center reaches 0.12 in (3mm), or any time you notice a reduction intraction.

More About: Drive Chain

Drive Chain


The master link is the most critical elementof drive chain security. Master links arereusable, as long as they remain in excellentcondition. We recommend installing a newmaster link retaining clip when the drivechain is reassembled.You may find it easier to install a new chainby connecting it to the old chain with amaster link and pulling the old chain toposition the new chain on the sprockets.

Inspect the sprocket teeth for wear ordamage. We recommend replacing thesprocket whenever a new chain is installed.Lubricate the drive chain.Pass the chain over the sprockets and join theends of the chain with the master link. Forease of assembly, hold the chain ends againstadjacent rear sprocket teeth while insertingthe master link.

You & the Environment

Tips

Owning and riding a motorcycle can beenjoyable, but you must do your part to protectnature. When you show respect for the land,wildlife, and other people, you also helppreserve the sport of off-road riding.

Following are tips on how you can be anenvironmentally-responsible motorcycle owner.

Stay on existing roads andtrails, avoid surfaces that are easily damaged,and ride only in areas approved for off-roadvehicles.

Loud motorcyclescan be offensive. Ride as quietly as possible,don’t remove your spark arrester, and don’tmodify the muffler or any other part of yourair intake and exhaust systems. Suchmodifications not only increase noise, theyalso reduce engine performance and may beillegal.

Use abiodegradeable detergent when you washyour motorcycle. Avoid aerosol spraycleaners that contain chloroflurocarbons(CFCs) which damage the atmosphere’sprotective ozone layer. Don’t throw cleaningsolvents away; see the following guidelinesfor proper disposal.

General Guidelines



If something goes wrong during a ride, the firstthing to do is stop as soon as you safely can.Do not continue riding if you have a flat tire, oryou hear an unusual noise, or your motorcyclejust doesn’t feel right. If you continue riding,you could cause more damage and endangeryour own safety.

After a stop, take time to assess the situation.Carefully inspect your motorcycle to identifythe problem, then consider your options beforeyou decide what to do.

Whatever the problem, the most important rulesare:

If a problem is relatively minor and you havethe tools, supplies, and skills to make apermanent repair, you may be able to fix it onthe trail and continue riding. Or, you may beable to make a temporary repair that allows youto slowly ride back to your base where you canmake a permanent repair or get help.

When a problem is more serious or you don’thave the tools, supplies, experience, or time todeal with it you need to choose the safest wayto get yourself and your motorcycle back tobase. For example, if you are close enough,you (or you and another person) might be ableto push it back.

Always put personal safety first.

03/06/17 14:30:34 31GCF670_127

119

If Your Engine Quits or Won’t Start



The next area to check is the fuel system:If the problem is relatively minor and youhave the tools, supplies, and skills to make atemporary repair, be sure to have permanentrepairs made as soon as possible.Do not continue riding if you are hurt oryour motorcycle is not in safe ridingcondition.

Additional recommendations for specificproblems follow.

If the engine wasn’t making any unusual noisesbefore it quit running, and it feels normal whenyou operate the kickstarter, you can probablyrule out a major mechanical problem.

Make sure there is enough gas in the tankand the fuel valve is at the ON or RESERVEposition.Check the fuel fill cap vent tube to see if it ispinched or obstructed.Turn the fuel valve OFF, disconnect the fuelline that goes from the fuel valve to thecarburetor, then momentarily turn the fuelvalve ON. If fuel does not flow out, there isan obstruction in the fuel tank or the fuelvalve.

03/06/17 14:30:44 31GCF670_128

120

If You Have a Flat Tire



How you handle a flat tire on the trail dependson how serious the tube or tire damage is, andwhat tools and supplies you have with you.

If you have a slow leak or a minor puncture,there are two ways to try making a temporaryrepair:

Use a tube patch kit to repair the puncture.(This requires removing the tire.)

Use an aerosol tire sealer to seal the punctureand inflate the tube. (This can be donewithout removing the tire or wheel.)

If the fuel system appears to be okay, check theignition system (this requires a spark plugwrench):

If you cannot identify or correct the problem,you will have to push your motorcycle back toyour base or get some help.

Operate the kickstarter while you watch thespark plug. If it sparks, the ignition system isprobably working. If there is no spark, installa new spark plug, if you have one with you.If there is still no spark, there is a problem inthe ignition system.

Disconnect the spark plug cap and removethe spark plug. Connect the spark plug cap tothe spark plug and ground the threadedportion of the spark plug on the cylinderhead.

Check that the spark plug cap isn’t loose ordisconnected.

03/06/17 14:30:54 31GCF670_129

121

If You Crash



If the leak is more serious, or a temporaryrepair doesn’t hold, the tube must be replaced.The tire will also need to be replaced if it isdamaged (page ). Replacing a tube or tireinvolves removing and re-installing the wheel(pages , ).

If you are unable to repair a flat tire on the trail,you will need to push the motorcycle back toyour base or send for help. We stronglyrecommend that you do not try to ride with aflat tire. The motorcycle will be hard to handle,and if the tire comes off the rim, it may lock upthe wheel and cause you to crash.

Personal safety is your first priority after anaccident. If you or anyone else has been injured,take time to assess the severity of the injuriesand whether it is safe to continue riding. If youcannot ride safely, send someone for help. Donot ride if you will risk further injury.

If you decide you are capable of riding safely,carefully inspect your motorcycle for damageand determine if it is safe to ride. Check thetightness of critical nuts and bolts securingsuch parts as the handlebar, control levers,brakes, and wheels.

If You Lose Your Key

QuickRef erence

If there is minor damage, or you are unsureabout possible damage but decide to try ridingthe motorcycle back to your base, ride slowlyand cautiously.

Sometimes, crash damage is hidden or notimmediately apparent. When you get home,thoroughly check your motorcycle and correctany problems you find. Also, be sure to haveyour Honda dealer check the frame andsuspension after any serious crash.

Be sure to record your key number in thesection at the rear of the manual.

You’ll need this number to have a duplicatekey made.

If you lose your key and aren’t carrying aduplicate, either get your spare or have onemade. If you don’t know your key number, callthe dealer you purchased your Honda from.They may have it listed in their records. If theydon’t, transport your motorcycle to them or thenearest Honda dealer. The dealer will probablyhave to remove the ignition switch assembly tofind the key number so they can make a key foryou.

03/06/17 14:31:08 31GCF670_131

123

If a Component Fails



If any component of the front brake systemis damaged, you may be able to ridecarefully back to your base using the rearbrake for slowing or stopping.If you damage a throttle cable or othercritical component, your motorcycle may beunsafe to ride. Carefully assess the damageand make any repairs that you can. But ifthere is any doubt, it’s best to beconservative and safe.

The drive chain, master link, brake lever orpedal, control cables, and other componentscan be damaged as you ride in dense brush orover rocky terrain. Making a trailside repairdepends on how serious the damage is andwhat tools and supplies you have with you.

If the drive chain comes off because themaster link clip gets knocked off, you maybe able to put the chain back on with a newmaster link. However, if the chain breaks ordoes other damage when it comes off, youmay not be able to make a trailside repair.

Source of Emissions

Exhaust Emission Control System

Crankcase Emission Control System



The combustion process produces carbonmonoxide and hydrocarbons. Control ofhydrocarbons is very important because undercertain conditions, they react to formphotochemical smog when subjected tosunlight. Carbon monoxide does not react inthe same way, but it is toxic.Honda Motor Co., Ltd. utilizes lean carburetorsettings and other systems to reduce carbonmonoxide and hydrocarbons.

The exhaust emission control system iscomposed of lean carburetor settings, and noadjustments should be made except idle speedadjustment with the throttle stop screw.The exhaust emission control system is separatefrom the crankcase emission control system.

The 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 thecarburetor.

Oxygenated Fuels


Some conventional gasolines are being blendedwith alcohol or an ether compound. Thesegasolines are collectively referred to asoxygenated fuels. To meet clean air standards,some areas of the United States and Canada useoxygenated fuels to help reduce emissions.

ETHANOL (ethyl or grain alcohol) 10% byVolumeYou may use gasoline containing up to 10%ethanol by volume. Gasoline containing ethanolmay be marketed under the name ‘‘Gasohol’’.

If you use an oxygenated fuel, be sure it isunleaded and meets the minimum octane ratingrequirement.

Before using an oxygenated fuel, try toconfirm the fuel’s contents. Some states/provinces require this information to be postedon the pump.

The following are the EPA-approvedpercentages of oxygenates:

MTBE (Methyl Tertiary Butyl Ether) 15% byVolumeYou may use gasoline containing up to 15%MTBE by volume.

METHANOL (methyl or wood alcohol) 5% byVolumeYou may use gasoline containing methanolcontaining up to 5% methanol by volume aslong as it contains cosolvents and corrosioninhibitors to protect the fuel system. Gasolinecontaining more than 5% methanol by volumemay cause starting and/or performanceproblems. It may also damage metal, rubber,and plastic parts of your fuel system.
