Polaris Sportsman Touring 850 HO Intl 12 13 Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The Polaris Sportsman Touring 850 HO is a premium long-wheelbase all-terrain vehicle designed for shared riding experiences with a passenger. Produced for the international market during model years 2012 and 2013, this machine represents the top tier of Polaris recreational ATV engineering. Polaris Industries, headquartered in Medina, Minnesota, has been a leader in powersports vehicle design since the first Snowmobile debuted in 1954. The Sportsman line evolved from the original Trail Boss in 1984 to become the best-selling ATV brand in North America. The Touring 850 HO features a stretched chassis with a dedicated passenger seat, handholds, and footpegs, making it one of the few ATVs designed for two-up riding. At its heart lies the proven 850cc liquid-cooled four-stroke V-twin engine equipped with electronic fuel injection, electronic power steering, and Polaris engine braking technology. With a gross vehicle weight rating exceeding 1300 pounds and towing capacity of 1050 pounds, the Sportsman Touring 850 HO serves both recreational trail riders and working utility applications. The independent rear suspension, sealed 255 mm front hydraulic disc brakes, and on-demand all-wheel drive system provide capable performance across diverse terrain from forest trails to farm properties.
