Polaris engineers came up with a simple solution for riders who love the XP 850’s excellent features, but may feel intimidated with an 850cc engine – offer the same features and chassis with a 550cc engine! As a smaller brother to the XP 850, the Sportsman XP 550 shares an almost identical chassis but with a liquid cooled, single cylinder, EFI equipped engine mated to a carefree, CVT transmission. The engine runs crisp and smooth, and the XP550 gets a high performance clutch with a roller system for a very noticeable snap off the bottom.
