Meet the ** 2027 Polaris 850 RMK® SPS 165 ES 7S**—a mountain sled that looks ready to pick a line on the horizon and make it happen. Finished in ****, it wears its attitude proudly, with a purpose-built stance that says it would rather be climbing into fresh snow than sitting still. (And if you’re the type who likes options, this model is also offered in **Gloss Black** and **INDY® Red / White Lightning / Gloss Black**.)
At the heart of this machine is the **Patriot™ 840**—a **liquid-cooled**, **2-cylinder**, **2-stroke** built in a **horizontal in-line** layout with **reed valve** induction. It’s **fuel injected** (gas/oil injected) and perfectly happy on **regular fuel**, so you can spend less time overthinking and more time riding. Hit the button and go: the **electric start** makes those cold-morning takeoffs feel a whole lot more civilized, while **reverse** helps when you’ve backed into a spot that suddenly looks deeper than expected.
Power delivery is handled through a **CVT** with **belt drive**, paired with a **P-85 / TEAM LWT** clutch setup. Translation: it’s built to keep the ride responsive and controllable when you’re feathering the **thumb throttle** through technical trees or rolling into a climb that demands commitment.
The ride is built around Polaris’ **MATRYX aluminum frame**, balancing strength and a clean, modern feel. With a **43.4-inch width** and an adjustable ski stance ranging from **36 to 38 inches**, you can tailor the front end to match your style—whether you want it more playful and quick to tip, or more planted for holding a line. Up front, the **RMK® React™ independent A-arm** suspension offers **9 inches of travel**, with **Polaris IFP adjustable gas shocks** and convenient **shock-mounted adjustment** so you can tune without turning a simple day into a garage project.
Out back, the **RMK rear suspension** brings **16 inches of travel** with **two rear shocks** plus a **center shock**, all **Polaris IFP adjustable gas** units. That means you can set it up for the way you ride and the way the snow is riding that day—deep and forgiving, set-up and fast, or a little bit of both.
And then there’s the track—the part that turns “maybe” into “let’s go.” The **Series 8** track measures **165 inches long**, **15 inches wide**, with **2.75-inch lugs**—a serious paddle built for mountain snow. Add in **Gripper® skis** with **carbide skags**, and you get a front end that can bite when you need precision, while the rear is busy digging, lifting, and driving forward.
Creature comforts aren’t forgotten either. You get a **one-piece vinyl seat**, **heated, adjustable driver hand grips**, and a **low, tinted LED** setup for crisp visibility. There’s smart awareness built in too, including **RIDE COMMAND™ GPS**, plus a **fuel level gauge** and a **temperature warning light**—because it’s a lot easier to enjoy the ride when the sled helps keep you informed.
From the **hydraulic disc rear brake** (RMK®) to practical touches like a **belt guard**, **snow guard**, and **skid-resistant** floor area, this RMK® SPS feels like it was designed for riders who measure a good day by the amount of untouched snow they found—and the stories they brought back with them.
