Page 68: Starting & Stopping The Engine
Starting & Stopping the Engine Always follow the proper starting procedure described below. For your safety, avoid starting or operating the engine in an enclosed area such as a garage. Your ATV’s exhaust contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or death.
Page 69: Starting Procedure
Starting & Stopping the Engine Starting Procedure This vehicle has a fuel-injected engine with an automatic choke. Follow the procedure indicated below. Any Air Temperature Press the start button with the throttle completely closed. The engine will not start if the throttle is fully open (because the electronic control module cuts off the fuel supply).
Page 70: Flooded Engine
Starting & Stopping the Engine Flooded Engine If the engine fails to start after repeated attempts, it may be flooded with excess fuel. To clear a flooded engine: Leave the engine stop switch set to RUN ( Open the throttle fully. Press the start button for 5 seconds.

Page 73: Shifting Gears
Shifting Gears UPSHIFTING SEQUENCE DOWNSHIFTING SEQUENCE (1) upshift switch (A) press (2) downshift switch Your ATV has five forward gears: 1, 2, 3, 4, and 5. Two gearshift switches are located next to the left handlebar grip: upshift ( ) and downshift ( To upshift the transmission, press the upshift switch ( ) once.
Page 74 2 mph (3 km/h). If the electric shift system malfunctions, the transmission cannot be shifted by pressing the gearshift switches. See your Honda dealer. (In an emergency, a gear may be selected manually so you may move the vehicle.
Page 75 Shifting Gears Downshift to a lower gear before you feel the engine laboring (lugging) at low rpm. Avoid downshifting to help slow your ATV when engine rpm is high. Downshifting when engine speed is near its allowable maximum may over-rev the engine and possibly cause damage. To prevent transmission damage, do not coast or tow the ATV for long distances with the engine off.
Page 76: Riding In Reverse
Riding in Reverse If you need to ride in reverse, make sure the area behind you is clear and only operate the ATV at low speed. Improperly operating in reverse could cause you to hit an obstacle or person behind you, resulting in serious injury.
Page 77 Riding in Reverse Your ATV may be equipped with a reverse speed limiter, which helps the vehicle to maintain a saf e speed while riding in reverse gear. Release the rear brake lever/parking brake lever. Open the throttle gradually and ride slowly. Do not open the throttle suddenly or make abrupt turns.
Page 78: Braking
Braking Your ATV is equipped with disc brakes on both front wheels which are hydraulically activated by operating the right brake lever. A single drum brake on the rear axle housing is mechanically activated by depressing the brake pedal or operating the left brake lever. Except TRX420TE: Although the front and rear brakes have separate controls, all four wheels are interconnected when your ATV is in the 4WD mode.
Page 79 Braking Your ability to brake in a turn and to brake hard in an emergency situation are important riding skills. When descending a long, steep grade, use engine compression braking by downshifting, with intermittent use of both brakes. Continuous brake application can overheat the brakes and reduce their effectiveness.
Page 80: Riding Your Atv
Riding Your ATV Making Turns Learn how to turn your ATV properly. Practice the techniques outlined in this section on level ground and at low speeds until you are confident in making turns. Turning improperly can make the ATV go out of control, causing a collision or overturn.
Page 81 Riding Your ATV Lean your body to the inside of a turn and forward. To make a turn on level ground: Steer the handlebar and lean your body toward the inside of the turn. Leaning helps balance the vehicle, and it feels more comfortable.
Page 82: Skidding Or Sliding
Riding Your ATV Skidding or Sliding The terrain surface can be a major factor affecting turns. Skidding during a turn is more likely to occur on slippery surfaces, such as snow, ice, mud and loose gravel. If you skid on ice, you may lose all directional control.
Page 83: Riding Up Hills
Riding Your ATV Riding Up Hills The ATV’s ability to safely climb hills largely depends on the rider’s skill and judgment. Begin by practicing on smooth, gentle slopes. As you gain experience, you’ll learn the hazards and your own limitations. You may then proceed to ride on more difficult terrain.
Page 84 Riding Your ATV Shift weight forward when climbing hills. Always check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces. To climb a hill, take a running start in an appropriate gear and speed for the conditions.
Page 85 Riding Your ATV Stalling the ATV and/or Rolling Backwards: If you incorrectly estimate climbing capability or terrain conditions, the ATV may not have enough power or traction to continue uphill. If this happens, the ATV can stall and/or roll backwards. Stalling, rolling backwards or improperly dismounting while climbing a hill could result in the ATV overturning.
Page 86 Riding Your ATV What to do after the ATV has stalled or rolled backwards: If the hill is too steep or too slippery, or if you have any doubt whether you can safely walk the ATV back down the hill, leave the vehicle where it is and get help.
Page 87: Riding Down Hills
Riding Your ATV Riding Down Hills It’s usually advisable to descend hills with the ATV pointed straight downhill. Avoid angles that would cause the vehicle to lean sharply to one side. Going down a hill improperly could cause loss of control or cause the ATV to overturn. Always follow proper procedures for going down hills as described in this owner’s manual.
Page 88: Crossing Or Turning On Hills Or Slopes
Riding Your ATV When you’ve selected a safe downhill path, shift into a lower gear, shift your weight back with your arms extended and braced against the handlebar, then go down slowly with the throttle closed. Use mainly the rear brake to control speed. Avoid using either the front brake or rear brake hard or abruptly when riding down hills.
Page 89 Riding Your ATV Crossing Hills or Slopes To maintain balance and stability when riding across a slope, you need to shift weight toward the uphill side of the vehicle. To do this, move your body off the center of the seat and lean toward the uphill side.
Page 90: Riding Over Obstacles
Riding Your ATV Riding Over Obstacles Before operating in a new area, check for obstacles. Watch out for bumps, rain ruts, potholes and other obstacles in the terrain. When you approach any obstacle, reduce your speed and be prepared to stop. Never try to ride over large obstacles, such as large rocks or fallen logs.
Page 91: Riding Through Water
Riding Your ATV Riding Through Water Your ATV is designed to travel through water up to approximately 10 inches (254 mm) deep. Before crossing a stream, make sure the water is not too deep or flowing too fast. The ATV tires have some ability to float. Operating this ATV through deep or fast-flowing water may cause a loss of traction and loss of control, which could lead to an accident.
Page 92: Parking
Parking Look for level parking area. Make sure the ground surface is firm. After bringing your ATV to a stop, hold the brakes while you shift into neutral. Set the parking brake. Turn the ignition switch OFF ( If you’re finished riding for the day, turn the fuel valve OFF. If it is necessary to start the engine when your ATV in gear and is stopped on a grade, rock the vehicle back and forth to allow shifting the transmission into neutral.

Tips Here’s helpful advice on how to prepare for an off-road adventure, how to transport and store your Honda, and how to be an environmentally responsible ATV owner. Preparing for a Ride ................What to Take to the Riding Area ..........
Page 182: Preparing For A Ride
Preparing for a Ride A safe and enjoyable ride begins with good planning and preparation. Always ride with at least one other person in case you have trouble, and let someone know where you’re going and when you expect to return. Before riding in an unfamiliar area, find out in advance if you need special permits, get maps so you can study the terrain, and talk to other riders who know the area.
Page 183: What To Take On The Trail
Preparing for a Ride What to Take on the Trail What you take with you during a ride depends on the kind of terrain, how long you expect to ride, how far you might go from your base camp or help, and how experienced you or your companions are in making repairs.
Page 184: Transporting Your Honda
Transporting Your Honda Do not tow your ATV behind a car or other vehicle. When you transport your ATV, we recommend that you carry the vehicle in its normal operating position (on all four wheels). Do not incline the vehicle upright on its rear end. This can damage the vehicle, and leaking gasoline could be a hazard.
Page 185 Transporting Your Honda Secure the vehicle with tie-down straps in the areas shown. Suitable tie-down straps are available from your Honda dealer. Ordinary rope is not recommended because it can stretch under load. Using tie-down straps in any other areas can damage your ATV.
Page 186: Storing Your Honda

You & the Environment Owning and riding an ATV can be enjoyable, but you must do your part to protect nature. When you show respect for the land, wildlife, and other people, you also help preserve the sport of off-road riding. Following are tips on how you can be an environmentally responsible ATV owner.
Page 191: Taking Care Of The Unexpected
Taking Care of the Unexpected With all the challenges you can encounter off-road, there’s a chance that sometime something may go wrong. This section gives practical advice to help you deal with a wide range of problems. Take time to read this section before you ride.
Page 192: General Guidelines
Taking Care of the Unexpected General Guidelines Keeping your ATV well-maintained is the best way to reduce the possibility of having a problem while riding. However, problems can arise even with well-maintained machines. Remember to take along your owner’s manual, the tool kit that came with your ATV, and any other items (such as tire repair supplies and additional tools) that might help you solve a problem on your own.
Page 193 Taking Care of the Unexpected Should you ever have a problem while riding, please follow these guidelines: Always put personal safety first. Take time to assess the situation and your options before deciding what to do. If the problem is relatively minor and you have the tools, supplies, and skills to make a temporary repair, be sure to have permanent repairs made as soon as possible.
