Sportsman 500 EFI and Sportsman 500 H.O.
Polaris Adds Electronic Fuel Injection to World’s Best-Selling Automatic ATV

Sportsman 500New in 2006, Polaris is adding electronic fuel injection to the best-selling automatic 4x4 ATV of all time. The new Sportsman 500 EFI delivers class-leading acceleration and smooth performance over all types of terrain. Polaris continues to provide its best-selling Sportsman 500 H.O. alongside the new EFI model.

First launched in selected Polaris Sportsman models in 2004, electronic fuel injection (EFI) has enjoyed tremendous market reception with new and repeat ATV buyers. In response to consumer demand, Polaris is now making EFI available on more of its full-size Sportsman ATVs.

As with other Sportsman models, EFI makes the Sportsman 500 more responsive and reliable in the type of rugged, off-road terrain that demands sudden and extreme changes in power and variations in speed. The EFI system uses a Throttle Position Sensor (TPS) to ensure the engine delivers extremely precise throttle response. This also gives Sportsman riders significantly better slow-speed driveability.

The EFI system compensates automatically for changes in altitude and temperature, ensuring the Sportsman 500 EFI starts readily in all conditions from –25 degrees F to 120 degrees F and operates smoothly at altitudes up to 10,000 feet. These ATVs also use standard 87-octane fuel and get better gas mileage than non-EFI engines.

“Much of the appeal of the Sportsman 500 EFI is that it excels in both recreation and utility use,” said Mike Dougherty, general manager of the ATV division. “It can haul heavy loads, run down a trail or transport gear to a hunting camp. Adding EFI to this best-seller makes it even more responsive and reliable, especially in tough terrain and extreme conditions.”

Much of that toughness and reliability come from Polaris’ legendary suspension system. Upgraded in 2005, this suspension system gives riders better handling by enabling the front tires to maintain more consistent contact with the ground. A wide front wheel stance and an improved MacPherson strut front suspension deliver 8.2 inches of suspension travel.

Sportsman 500 EFIAlso native to the Sportsman is Polaris’ long-travel Independent Rear Suspension (IRS) with an anti-roll bar. This fully-independent, progressive-rate rear suspension delivers a smooth ride, 9.5 inches of travel and an industry-leading 11.25 inches of ground clearance. Together with the improved front suspension and wider front wheel stance, the IRS delivers enhanced handling, tracking and stability.

At the core of the Sportsman 500 EFI is a powerful liquid-cooled, electronically fuel-injected, single cylinder 499cc engine. The EFI and carbureted model share a 4-valve, 4-stroke high output engine with an electric start.

Both Sportsman power plants are matched with an automatic Polaris Variable Transmission (PVT) to deliver class-leading towing, hauling, payload and top speed. This PVT is the industry’s best-selling automatic transmission. The PVT continually senses engine speed and vehicle torque load and provides the proper amount of power to the drive wheels. The Polaris EBS (Engine Braking System) assists in braking on downhill operation. EBS is standard on the Sportsman 500 EFI.

Because the Sportsman 500 EFI and Sportsman 500 H.O. use Polaris On-Demand All-Wheel drive, riders get the traction only achieved with true all-wheel drive. As soon as the rear wheels lose traction, the Polaris AWD system automatically engages both front wheels to provide full torque to all four wheels. Power is delivered to all four wheels via a 4-wheel independent shaft drive. This produces a performance vastly different from competitive 3 1/2 wheel drive limited slip systems.

The ride in AWD is smoother than ever with the introduction of double offset joint (DOJ) half-shafts last year. They reduce vibration and improve the ride when the Sportsman is accelerating, decelerating, running uphill or maneuvering in AWD. The Polaris AWD system automatically reverts to 2WD when AWD is no longer needed.

Premium Sportsman Features
In 2005, Polaris introduced many new elements that further established the popularity of the Sportsman 500. The Sportsman 500 EFI and Sportsman 500 H.O. continue to incorporate all of these newer elements and some traditional premiums found only on Polaris ATVs. Among them are:

  • Tough bodywork with better splash protection and easy access to
    several maintenance and adjustment points. The front bumper is a tough composite material while the wider floorboards are practically
    unbreakable and offer better splash protection.
  • In front there is an integrated, composite storage box. The storage box lid has numerous tie-down points and can be lifted for access to the storage box even when gear is strapped to it.
  • In back, a tough composite rear rack accepts Pure Polaris Lock & Ride™ accessory mounts. These mounts use expansion anchor technology that allows a rider to attach accessories in seconds. The rack has numerous tie-down points and under the rear rack is an easy-access 10x10 inch storage box and a 1.25 inch standard receiver hitch.
  • 26 inch PXT radial tires on the EFI are extremely tough and puncture-resistant. Designed exclusively by Polaris, these 3-Star tires deliver a better ride than bias ply tires and have an aggressive, high-traction tread pattern.
  • Lighting on the Sportsman was dramatically improved in 2005 and the Sportsman 500 EFI benefits from the new look and functionality. Up front, the high-beam headlights include reflector lens optics that cast a wider beam. The two bumper-mounted low-beam lights include reflector lens optics to increase brightness and deliver 37 watts each.
  • Twin work lights in the rear are an industry first and are controlled by an On/Off switch on the headlight pod.
  • Twin brake light/tail lights are standard.
  • Polaris’ single-lever all-wheel hydraulic disc brakes with stainless steel braided lines and an auxiliary hydraulic rear foot brake.
  • The drum-shift provides a simple inline shift pattern that helps make plowing easier and allows riders to shift easily among High, Low, Neutral and Reverse. The transmission also has a Park position.
  • VDO instrumentation keeps riders aware of the vehicle’s operating status. There is an electronic fuel gauge with a low-fuel flasher and data concerning speed, engine RPM, maintenance indicators and a gear position indicator.
