Specifications

  • The electronic power steering system and new suspension increases the Polaris Sportsman's ease of handling and responsiveness
  • The model has an electronic fuel injection system for greater fuel efficiency, performance and power
  • Polaris sold 3187 ATVs in Australia last year, propelling the marque into fourth largest ATV sales for 2008
  • Optional Polaris accessories, including ‘Lock and ride’ top boxes for greater waterproof storage, and front and rear safety bars, are available


The Polaris Sportsman’s 549cc liquid-cooled powerplant has been turned 90 degrees into a north-south position for better drivetrain shaft alignment to the driving wheels from the engine, reducing general wear and tear. The new design single overhead cam engine gives more power and torque, and is fuelled by an electronic fuel injection system for greater fuel efficiency and power.

The transmission is now a bolt-on unit to the engine rather than a separate item, similar to a tractor, with the variable drive belt now under full time tension.

The independent suspension has rolled double ‘A’ arms holding the front and rear wheels in place. This holds the XP550 steady over uneven ground and also offers a high 305mm ground clearance between the wheels. It also has patented anti kick-back front suspension.

The Polaris’ wheels take a standard 14" diameter tyre to ride the bumps cleaner and larger diameter disc brakes and bigger brake callipers on each wheel to improve stopping power.

The Polaris ADC (Automatic Descent Control) engine brake system helps slow it down when coming off a steep slope, with or without the brakes. This kicks in below 24kmh, when the ADC 4x4 mode on the handlebar switch is selected.

2WD or 4WD can be selected without the ADC function for going downhill with a load. When in either 4WD or ADC 4x4 mode, drive to the front wheels only comes in when the rear wheels begin to slip. As soon as it measures rear wheel slip by more than an eighth of a turn compared to the front wheel, drive to the front wheels via a wet brake-pack kicks in.

The XP850 EPS is also available with a 70hp 850cc twin cylinder engine.
