There's no real comparison. An 850 XT outlander will absolutely stomp a 570 DPS. Not only by horsepower ratings, but by clutch design as well, tire diameter, and ecu tuning. Kinda pointless vid. A better comparison would be an 850 sportsman versus an 850 outlander, or a 750 brute force vs a 750 kingquad. Can't really compare a small displacement machine to a big bore, unless it's a racing quad with manual clutch and gears versus a belt driven big bore. In that case the racing quad would win 9 times out of ten. Kinda like comparing a naturally aspirated machine versus a turbo charger. Unless you up the displacement substantially, usually a turbo machine will spank it.
