Meet the 2027 Polaris 850 RMK® SPS 155 ES in ****—a mountain sled that looks as ready for the ridgeline as it feels the moment you thumb the throttle. (And if you’re the type who likes options, this model is also offered in **Gloss Black** and **INDY® Red / White Lightning / Gloss Black**.) In this finish, it has that clean, purposeful vibe that says you came to carve, climb, and disappear into fresh snow—then come back grinning.
At the heart of it all is the Patriot™ powerplant: an 840cc, liquid-cooled, 2-cylinder, 2-stroke horizontal in-line with reed valve breathing and fuel injection. Translation: it’s built to respond fast and pull hard when the mountain asks for more. It sips regular fuel, feeds through a single exhaust, and keeps things crisp with gas/oil injection—no fuss, just go. When the day starts cold and your gloves are already on, electric start is the kind of convenience you’ll appreciate more than you expected.
Power meets the snow through a continuously variable (CVT) setup with belt drive and a P-85 / TEAM LWT clutch pairing that’s all about keeping you in the sweet spot while the terrain changes its mind every 20 feet. Need to back out of a sketchy spot or re-line in tight trees? Reverse is on board, because mountain riding is an art—and sometimes art needs a quick undo.
The RMK® SPS 155 ES is sized to feel nimble without giving up the footprint you want when conditions get deep. It stretches 126.7 inches long, stands 53 inches tall, and keeps a 43.4-inch width that’s built for threading lines and setting edges. Adjustable ski stance (36 to 38 inches) lets you tune the feel, whether you want a touch more precision or a bit more stability. And at 446 lbs dry, it stays in that sweet zone where the sled feels lively when you’re working a sidehill or popping up and over a rollover.
Underneath, the MATRYX aluminum frame provides the backbone, while the RMK® React™ independent A-arm front suspension brings 9 inches of travel to keep the skis tracking and predictable when the snow turns choppy. Out back, the RMK rear suspension delivers 16 inches of travel, controlled by Polaris IFP adjustable gas shocks (front, rear, and center) with coil-over support and shock-mounted adjustment. In other words, you can set it up for your style—whether your ride is all about playful transitions or all about holding a line when the slope tilts steeper than your comfort zone.
The Series 8 track is the finishing touch that makes the mountain feel like home: 155 inches long, 15 inches wide, with 2.75-inch lugs ready to bite, lift, and churn. Up front, Gripper® skis (plastic, with carbide skags) help keep steering honest when you’re picking your way into the next bowl. Braking is handled by an RMK® hydraulic disc rear brake—strong, consistent, and ready when gravity gets ambitious.
Inside the cockpit, it’s all business in the best way: a one-piece vinyl seat for a single rider, rubber hand grips with adjustable heated grips for the driver, and LED lighting with a tinted lens. Add practical alerts like a temperature warning light and a fuel gauge (backed by an 11-gallon tank), plus smart touches like a belt guard, snow guard, and skid-resistant running boards, and you’ve got a sled that’s built to be ridden the way mountain sleds should be—often, hard, and with a big laugh inside your helmet.
The 2027 850 RMK® SPS 155 ES in isn’t trying to be everything. It’s focused. It’s sharp. And it’s ready to turn a blank mountainside into your personal signature.
