Meet the 2027 Polaris 850 RMK® SPS 146 in ****—a mountain sled that looks like it was built to disappear into a storm and then reappear on top of the next ridgeline, grinning. And while the RMK lineup also comes in **Gloss Black** or **INDY® Red / White Lightning / Gloss Black**, this one wears **** with the kind of attitude that says, “Go ahead—pick your line. I’ll meet you up there.”
At the heart of the fun is Polaris’ **Patriot™** powerplant: an **840cc**, **liquid-cooled**, **2-cylinder**, **2-stroke** built in a **horizontal in-line** layout with **reed valve** breathing and **fuel injection**. Translation: crisp response when you squeeze the **thumb throttle**, clean fueling when conditions change, and the kind of snap that makes tight trees feel less like obstacles and more like a slalom course. It runs on **regular fuel**, and the **gas/oil injected** setup keeps things simple—just focus on the snow and the next turn.
When the terrain starts doing what mountain terrain does—tilting, dropping, and generally daring you to commit—the **MATRYX aluminum frame** keeps the package light and purposeful. With a **dry weight of 423 lb**, it’s built to feel eager when you lean it over and ask it to carve. The sled’s stance can be set between **36" and 38"** at the skis, giving you the ability to tune the feel—whether you want it a touch more planted or a bit more nimble for sidehilling and quick transitions.
Up front, the **RMK® React™** suspension uses an **independent A-arm** design with **9 inches** of travel, backed by **Polaris IFP adjustable gas shocks with remote reservoirs** and **shock-mounted adjustments**. Out back, you get **16 inches** of travel with **two rear shocks**, plus a **Polaris IFP center shock**—all adjustable, all ready for the kind of repeated hits that turn lesser setups into arm workouts. The point isn’t to list parts; it’s to say the ride stays composed when the snow turns choppy and stays predictable when you’re picking your way through technical sections.
Then there’s the business end: a **Series 6** track at **146" long** and **15" wide**, carrying **2.6" lugs** that love deep snow. That lug height is the difference between “stuck and shoveling” and “still moving while laughing,” especially when you’re trying to keep momentum on a steep pitch or pop over a drifted rollover. And when you point it into a traverse, the **Gripper® composite skis** with **carbide skags** help keep the front end honest.
Power delivery is handled by a **CVT** with **belt drive** and **P-85 / TEAM LWT clutching**, so it’s happy to move from delicate throttle control to hard pull without needing you to think about gear changes. And yes—there’s **reverse**, because sometimes the mountain reminds you that backing out gracefully is also a skill.
Practical touches show up everywhere. An **LED** headlight with a **tinted, low-height** lens keeps things sharp when daylight fades. You’ve got a **fuel gauge**, a **temperature warning light**, and **heated, adjustable driver grips** for those long climbs when the air turns bitey. The **one-piece vinyl seat** keeps the setup clean and focused for a single rider, and details like **skid-resistant** footing, **hand guards**, a **belt guard**, **snow guard**, and **tunnel braces** all reinforce that this sled is meant to be used, not just admired.
Bottom line: this **** 850 RMK® SPS 146 is a mountain machine that feels like it was designed around one idea—make the next line more tempting than the last. Fill the **11-gallon** tank, grab the bars, and go find the kind of snow you’ll be thinking about all summer.
