2027 Polaris 850 RMK® SPS 146 ES

Meet the **2027 Polaris 850 RMK® SPS 146 ES** in ****—a mountain sled that looks like it was built to disappear into winter and then loudly reappear on top of the next ridge. It’s the kind of machine you park at the trailhead and immediately start thinking, “Okay… which line am I finally brave enough to try today?”



At the heart of it is Polaris’ **Patriot™** powerplant: a **liquid-cooled, 2-cylinder, 2-stroke** with **840cc** of eager attitude, breathing through a **reed valve** setup and fed by **fuel injection**. It runs on **regular fuel** with **gas / oil injection**, so you get that crisp response without the ritual of mixing. Tap the **thumb throttle** and let the **single exhaust** do its thing while the **CVT** keeps the power smooth and ready as terrain changes by the second. And when the day starts cold and your gloves feel like frozen mitts of regret, you’ll appreciate the simple luxury of an **electric start**—because in the mountains, effort is better saved for sidehilling, not yanking cords.



This sled is built on the **MATRYX aluminum frame**, a platform that feels purpose-made for technical terrain: strong where it counts, and tuned for control when the snow gets weird—wind crust, chopped leftovers, or that deceptive powder that’s deeper than it looks. With a **36–38 inch adjustable ski stance**, it can be dialed for quick, precise steering or a bit more stability depending on the day’s mission. Out front, the **RMK® React™ independent A-arm suspension** delivers **9 inches of travel**, backed by **Walker Evans Racing (WER®) adjustable gas shocks with remote reservoirs**. Translation: when you point it into rough approaches or roll into surprise hits, it stays composed instead of pitching a tantrum.



The rear end is ready for the steep and deep, too. You’ve got **16 inches of rear travel** and a **two-shock rear suspension** setup, with **Polaris IFP adjustable gas shocks with remote reservoirs** at the rear and center. It’s a configuration that’s happy to climb, carve, and reset—so you can keep working the slope instead of wrestling the chassis. When it’s time to scrub speed, the **RMK® hydraulic disc rear brake** delivers predictable control, and yes, there’s **reverse** for those moments when you discover your “shortcut” ends in an awkward dead-end pocket.



Underneath, the business end is all mountain. The **Series 6 track** stretches **146 inches** long and **15 inches** wide, with a serious **2.6-inch lug** that’s built to bite, claw, and keep pushing when gravity starts negotiating. Up front, **Gripper® composite skis** with **carbide skags** help keep the nose tracking when you’re threading trees or setting an edge across a slope.



Comfort and practicality show up in the right places. The **one-piece vinyl seat** is set up for a single rider—because this is a focused tool, not a passenger cruise. The **driver floorboards** are **skid resistant**, and details like **hand guards**, a **snow guard**, **tunnel braces**, and a **belt guard** are there to help you keep riding when conditions get messy. You also get **heated, adjustable driver hand grips**, because warm hands make better decisions. The lighting is **LED** and **tinted**, and you’ve got a **fuel level gauge** plus a **temperature warning light** to keep you informed when the ride goes long.



With an **11-gallon fuel capacity** and a **dry weight of 447 lbs**, this RMK® SPS feels like it was made for riders who measure their days in elevation gained, not miles logged. If you want a mountain sled that’s lively, sharp, and ready to chase fresh lines until the last light fades, this one’s already itching to point uphill.
