What sets the 2026 Polaris Sportsman 570 Trail apart is its balanced combination of power and practicality, highlighted by a ProStar 4-stroke SOHC single cylinder engine delivering 32 hp from a compact 567 cc package. The liquid-cooled EFI setup feeds reliable torque at low revs, while the One-touch on-demand AWD/2WD drivetrain gives you traction where you need it. Add a towing capacity of 1350 lbs and a standard payload of 485 lbs, and this ATV is ready to handle gear, supplies, and the occasional heavy-duty task without slowing you down. Built for controlled capability, it rides on Sealed arched dual A-arms up front and Sealed Dual A-Arm IRS in the rear, with front travel of 8.88 inches and rear travel of 9.48 inches for a smooth ride over uneven terrain. Braking is confident with a three-wheel hydraulic disc on both ends and a hydraulic rear foot brake, ensuring predictable stops under load. The chassis measures 48 inches in width and 83 inches in length, with a wheelbase of 4.21 feet and a saddle-style seat at 2.77 feet high, providing a compact stance that still offers a capable platform for one rider. Practical design details abound, including a 4.5-gallon fuel tank for extended rides, a 180-pound rear rack capacity, and a dry weight of 847 pounds that keeps the center of gravity balanced on varied terrain. Wheels listed as 1 ft and tires sized 25 x 8-12 up front and 25 x 10-12 in the rear reinforce its ready-to-ride, all-conditions DNA. View the Polaris Sportsman(R) 570 Trail at Vallely Sport & Marine.
