Meet the ** 2027 Polaris 850 RMK® SPS 146 7S**, a purpose-built **mountain** sled that looks as sharp standing still as it does carving a fresh line. This one shows up in ****, a color that fits the RMK attitude perfectly—clean, bold, and ready to disappear into the treeline the moment you squeeze the thumb throttle. (And if you’re shopping shades, this model is also offered in **Gloss Black** and **INDY® Red / White Lightning / Gloss Black**.)



At the heart of it is the **Patriot™** powerplant: a **liquid-cooled, 2-cylinder, 2-stroke** with **reed valve** induction and **fuel injection**. Displacement lands at **840 cc (51.2 ci)**, and it’s matched to a **CVT transmission** driven by **belt**—built to keep power flowing smoothly when the terrain goes from “open meadow” to “why is that hill vertical?” A simple **pull starter** keeps things straightforward, it drinks **regular fuel**, and the **gas / oil injected** setup means you can focus on the line instead of the mixing. When you need to back out of a tight spot (because mountain riding happens), **reverse** is there.



This RMK rides on the **MATRYX aluminum frame**, keeping things light and responsive, with a **dry weight of 425 lbs** and an **engine displacement-to-weight** figure of **1.98 cc/lb**. Dimensions are trail-to-tree friendly at **122.8 in** long and **43.4 in** wide, with an adjustable ski stance between **36 and 38 inches** to suit your feel. Under your boots, the running boards are **skid resistant**, and details like **tunnel braces**, a **belt guard**, **hand guards**, and a **snow guard** are all there to support the kind of riding where conditions change by the minute.



Up front, the **RMK® React™** **independent A-arm** suspension delivers **9 inches** of travel, controlled by **Polaris IFP adjustable gas shocks with remote reservoirs**. Out back, the RMK rear suspension brings a full **16 inches** of travel with **two rear shocks**, plus a matching **Polaris IFP** center shock—also adjustable gas with a remote reservoir. Translation: you get a setup designed to stay composed when you’re threading chop, sidehilling, or setting up for that one clean move you’ll replay in your head all week.



Traction comes courtesy of the **Series 6** track: **146 inches** long, **15 inches** wide, with tall **2.6-inch** lugs ready to dig in when the snow turns deep and the climb turns serious. Steering is handled by a **ProTaper™** bar with **manual** steering, while **composite Gripper® skis** and **carbide skags** help keep your front end tracking where you point it—even when the snowpack tries to negotiate.



You also get a modern cockpit feel without losing the “ride first” mindset. A **low tinted LED** display keeps info clear, and **RIDE COMMAND™ GPS** adds confidence when the mountains start looking the same in every direction. There’s a **fuel level gauge** plus a **temperature warning light**, and the tech side is ready too with **Bluetooth® audio** and **mobile app instrumentation**. Top it off with **heated, adjustable driver grips**, and you’ve got a machine that’s as happy chasing sunrise corduroy as it is hunting powder stashes long after the parking lot is a memory.



In ****, this 850 RMK® SPS 146 7S isn’t just a new snowmobile—it’s a fresh invitation to aim at the horizon and see what the next ridge looks like up close.
