Description

Carve your name into the next ridgeline on a **Gloss Black** 2027 Polaris 850 RMK® SPS 155 ES 7S—a mountain sled that looks as sharp standing still as it feels the moment the snow turns deep and the trees start closing in. (And if you’re the type who likes options, this model also comes in **INDY® Red / White Lightning / Gloss Black**—but there’s something especially stealthy and purpose-built about this one in Gloss Black.)



At the heart of it is the **Patriot™ 840**—a liquid-cooled, **2-cylinder, 2-stroke** setup with **reed-valve** breathing and **fuel injection**. It’s the kind of engine that feels eager without feeling fragile: crisp response when you’re threading technical lines, and steady pull when the climb gets long. Hit the **thumb throttle**, let the **CVT** do its smooth, belt-driven thing, and you’ll understand why mountain riders obsess over that instant, on-demand surge. When it’s time to reposition or back out of a tight spot, **reverse** is right there—because digging out is only fun the first time.



This sled is built around Polaris’ **MATRYX aluminum frame**, keeping the feel light and precise while you move around the machine. The ergonomics are all business: a **one-piece vinyl seat** for a **single rider**, and a driver-focused layout with **skid-resistant** running boards so you can shift your weight confidently when the hillside demands it. It’s also sized to fit the mission—about **126.7 inches long**, **43.4 inches wide**, and **53 inches tall**—with an adjustable ski stance from **36 to 38 inches** to help dial in the feel for your terrain and style.



Up front, the **RMK® React™ independent A-arm** suspension gives you **9 inches** of travel, controlled by **adjustable gas IFP shocks** from Polaris. Out back, the RMK rear suspension stretches to **16 inches** of travel with **two rear shocks** plus a **center shock**, all **adjustable gas IFP** units—because mountain conditions don’t stay consistent for more than a few turns. One moment it’s soft and surfy, the next it’s choppy and tracked out, and having on-sled adjustability helps you keep the ride composed without killing the fun.



Point it where you want to go with **ProTaper™ handlebars** and a manual steering setup that feels direct, predictable, and connected. The sled rides on **Gripper® skis** with **carbide skags**, a combination that helps the front end bite when you need it—especially when you’re balancing that fine line between confident steering and effortless maneuvering.



And then there’s the part that makes an RMK feel like an RMK: the track. This one wears a **Series 8**—**155 inches long**, **15 inches wide**, with a tall **2.75-inch lug** profile. It’s built for that deep-snow rhythm: keep momentum, float up, and drive forward when the terrain turns three-dimensional. The **hydraulic disc rear brake** is there when you need to check speed quickly and deliberately—useful on steep approaches, tight descents, and those “let’s take a look before we commit” moments.



Cold days don’t get a veto, either. You’ve got **adjustable heated grips** for the driver, plus smart, simple alerts like a **temperature warning light** and a **fuel level gauge** so you can stay focused on the line instead of guessing. Lighting is **LED** with a **tinted, low** profile—clean, modern, and ready for the kind of winter light that disappears early behind the peaks.



With an **11-gallon** fuel capacity and a dry weight of **448 lbs**, this Gloss Black RMK SPS keeps things intentionally lean and mission-first. It’s the sled you pick when you want your winter stories to start with, “So I found this line…” and end with the quiet satisfaction of fresh snow settling behind you.
