Except TRX420TM: Although the front and rear brakes have separate controls, all four wheels are interconnected when your ATV is in the 4WD mode.
  • Page 86 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 87: 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 88 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 89: 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 90: 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 91 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 92 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 93 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 94: 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 95: 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 96 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 centre of the seat and lean toward the uphill side.

  • Page 97: 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 98: Riding Through Water

  • Page 190: 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 191: 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.

    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 petrol could be a hazard.
