2027 Polaris 850 RMK® SPS 165 ES 7S

Draped in , the 2027 Polaris 850 RMK® SPS 165 ES 7S looks like it was built to disappear into a fresh mountainside—right up until you crack the throttle and the whole basin knows you’re there. (If you’re the kind of rider who likes options, this model also comes in Gloss Black and INDY® Red / White Lightning / Gloss Black—but this one wears with serious attitude.)



At the heart of this mountain machine is the Patriot™ 840— a liquid-cooled, 2-cylinder, horizontal in-line 2-stroke with reed-valve breathing and clean fuel injection. Translation: it’s snappy, responsive, and eager to play when the terrain turns steep and technical. It runs on regular fuel, sips from an 11-gallon tank, and uses gas/oil injection so you can focus on the line ahead instead of the logistics. And when the day starts cold and quiet, electric start means you’re not wasting stoke (or energy) before the first climb.



Power gets to the snow through a continuously variable transmission with belt drive and a P-85 / TEAM LWT clutch setup—smooth when you want it smooth, ready when you need it ready. Add in reverse, and you’ve got a little extra confidence for those “I swear this was the right chute” moments where backing out beats wrestling around.



The MATRYX aluminum frame helps keep everything feeling purposeful and precise, and at a 454 lb dry weight, it’s built to be handled—not just ridden. The stance is adjustable from 36 to 38 inches, letting you dial in how planted (or how flickable) you want the front end to feel as conditions change from deep and dreamy to tracked-out and choppy.



Up front, the RMK® React™ independent A-arm suspension delivers 9 inches of travel with shock-mounted adjustment, backed by Polaris IFP adjustable gas shocks. Out back, the RMK rear suspension brings a full 16 inches of travel with two rear shocks plus a center shock—again, Polaris IFP adjustable gas units—so you can tune the sled to match your riding style, your snowpack, and your appetite for sending it. When it’s time to rein things in, the RMK® hydraulic disc brake is there with the kind of control you appreciate on steep sidehills and quick drops.



And then there’s the part that defines the personality: a Series 8 track measuring 165 inches long, 15 inches wide, with tall 2.75-inch lugs. That’s mountain-minded footprint and bite—built for traction when you’re climbing, flotation when you’re surfing, and commitment when you point it into the kind of terrain that makes your friends go quiet.



From the cockpit, it’s all about riding longer and riding smarter. You’re perched on a one-piece vinyl seat, hands on ProTaper™ bars, with a thumb throttle that feels made for quick corrections and precise control. The grips are heated and adjustable—because warm hands make better decisions—while the low, tinted LED lighting keeps visibility crisp when the day runs late. You’ll also get clear warning cues (temperature light, fuel gauge) so surprises stay in the terrain, not in your tunnel.



Navigation and ride info come via RIDE COMMAND™ GPS, which is perfect for the riders who like exploring just as much as they like climbing—because the best backcountry stories are the ones you can actually find again.



Finished in , this 850 RMK® SPS 165 ES 7S isn’t trying to be subtle—it’s trying to be unforgettable. It’s a mountain sled built for riders who measure winter in elevation gains, fresh lines, and the grin you can’t wipe off after the last pull.
