Built around Polaris's atv motorcycle platform, the 2011 Polaris Sportsman XP 850 EPS utilizes a 850 cc (51.9 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 70 HP (51.1 kW), transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 82.4 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Sportsman XP 850 EPS measures 355.2 kg (783 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (5.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,346 mm (53 in) wheelbase engineered for quick, flickable steering geometry. The 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
