Built around Polaris's atv motorcycle platform, the 2021 Polaris Scrambler 850 features a 850 cc (51.9 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 78 HP (56.9 kW), transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 91.8 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 Scrambler 850 measures 333 kg (734 lbs) dry, translating to a power-to-weight ratio of 0.23 HP/kg (4.27 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 19.9-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
