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
