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. 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 helmet and protective apparel.Instruct your passenger on holding onto theseat strap or your waist, leaning with you inturns, and keeping their feet on the footpegs,even when the vehicle is stopped.

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) or a state approved trainingcourse. New riders should start with the basiccourse, and even experienced riders will find theadvanced course beneficial.

Don't Drink or Use Drugs and RideAlcohol or drugs and riding don't mix. Even onealcoholic drink can reduce your ability torespond to changing conditions, and yourreaction time gets worse with every additionaldrink. The same is true for drug use. Don't drinkor use and ride, and don't let your friends do iteither.

Keep Your Honda in Safe ConditionIt's important to keep your vehicle properlymaintained and in safe riding condition.Having a breakdown can be difficult, especiallyif you are stranded off-road far from your base.Inspect your vehicle before every ride andperform all recommended maintenance. Neverexceed load limits (2 P. 17), and do not modifyyour vehicle or install accessories that wouldmake your vehicle unsafe (2 P. 15).

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.

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.

# Anti-lock Brake System (ABS)CRF300LAThis model is equipped with an Anti-lock BrakeSystem (ABS) designed to help prevent thebrakes from locking up during hard braking.● 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 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 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.
