When it was introduced 2 years ago, the Polaris Sportsman XP 850 set a new standard for big bore utility ATVs that has yet to be matched. In our experience logging over a thousand odd trail miles, reliability has been perfect, and it has never let us down. The engine runs smooth, quiet, and crisp thanks to electronic fuel injection. We’re especially happy to report maintenance tasks are a breeze due to a spin off oil filter, a cartridge type air filter, and a handy, easy access dipstick (Take note Suzuki). Power from the twin cylinder engine is excellent, and we detect absolutely no vibration from the engine which is mounted parallel to the long axis of the chassis for improved power delivery and excellent ergonomics by narrowing the distance between the rider’s feet. The XP 850 is comfortable to ride all day, with all controls at the rider’s finger tips, and a handy, center mounted, digital LCD display shows all vital info. The suspension on the XP delivers a plush, controlled ride thanks to dual A-arms up front and Independent Rear Suspension. Massive disc brakes provide excellent stopping power and are tucked inside stylish, cast aluminum wheels, and the entire chassis geometry has been designed to optimize handling. As a package, the XP 850 excels in nearly every area. While they are extremely adept work machines all week, they’re equally capable of weekend adventures or trips back to the deer stand. For all those reasons and a hundred more, the Polaris Sportsman XP 850 is our pick for the best Open Class Utility ATV of 2010.
