Draped in ****, this **2027 Polaris 850 RMK® SPS 155** looks like it was built for one thing: slipping off the groomed path and into the kind of terrain that makes your heart thump a little louder. It’s a mountain sled with a stance and attitude that say “pick a line,” whether that line is a steep sidehill, a fresh pillow stack, or an untouched meadow that’s begging for the first track.
At the core is Polaris’ **Patriot™** powerplant—an **840cc**, **liquid-cooled**, **2-cylinder**, **2-stroke** that’s **fuel injected** and **oil injected**, so it’s ready for long days of throttle-on fun without drama. The pull start keeps things simple and purposeful, and it sips **regular fuel**—because adventure is complicated enough without having to hunt down something special. Feed it air, and the **reed valve** setup answers back with that crisp, eager response riders love when they’re dancing between trees or popping over windlips.
Power is delivered through a **CVT** with **belt drive**, paired with a **P-85 / TEAM LWT** clutch setup that’s all about smooth, usable drive when you’re constantly transitioning—on the gas, off the gas, rolling into the next move. And when the moment calls for a reset, **reverse** is there to help you back out of tight spots without turning the whole mountainside into a three-point turn.
The personality of this sled really shines once the snow turns deep. The **Series 8 track** stretches **155 inches** long and **15 inches** wide, with towering **2.75-inch lugs** that bite, claw, and keep pushing when the powder gets heavy. It’s the kind of setup that encourages you to go a little farther, climb a little higher, and cut a little sharper—because you can feel the traction working with you instead of against you.
Up front, the **RMK® React™ independent A-arm** suspension brings **9 inches** of travel, backed by **Polaris IFP adjustable gas shocks**. Out back, the **RMK rear suspension** delivers a generous **16 inches** of travel with **two rear shocks** plus a **center IFP**—all adjustable, all ready to be tuned for your riding style and the day’s conditions. Whether you’re threading technical lines or opening it up across a rolling face, the chassis stays composed and predictable, helping you ride longer and harder with less fatigue.
Speaking of chassis, the **MATRYX aluminum frame** keeps things strong and purposeful, while the sled’s **423-lb dry weight** hits that sweet spot for a mountain machine that feels eager to respond without feeling twitchy. The sled measures **126.7 inches** long and **43.4 inches** wide, with an adjustable ski stance from **36 to 38 inches**—handy for dialing in how planted or playful you want it to feel. The **Gripper® skis** (plastic, with **carbide skags**) add bite and control when the snow firms up or the approach gets tracked out.
Control points are built for real riding days. You’ve got **ProTaper™ handlebars** with a classic **thumb throttle**, **heated driver grips** that are **adjustable**, and a **low tinted LED** setup that looks sharp and keeps visibility clean when the light gets flat. The **one-piece vinyl seat** is shaped for moving around—because mountain riding isn’t a sit-still kind of sport. Add in practical touches like a **fuel gauge**, a **temperature warning light**, plus protections like a **belt guard** and **snow guard**, and it’s clear this sled was designed to be ridden, not just admired.
And yes, it wears **** like it owns the backcountry—because it does. If you want a mountain sled that’s playful when you want it, serious when you need it, and always ready to chase the next untouched slope, this RMK® SPS 155 is calling your name.
