Meet the 2027 Polaris Patriot Boost PRO-RMK® 155 in ****—a mountain sled that looks as fast standing still as it feels the moment you snap your thumb onto the throttle. This is the kind of machine that turns a blank powder face into a playground and makes you “accidentally” take the long way back to the trailer, because why wouldn’t you?
At the heart of it is the Patriot™ Boost: an **840cc**, **liquid-cooled**, **turbocharged** **2-cylinder**, **2-stroke** with **fuel injection** and reed-valve breathing. Translation: it’s built to bring big energy to big terrain, delivering that crisp, immediate response you want when you’re picking a line, correcting mid-climb, or hopping from one pocket to the next. It sips **regular fuel**, uses **gas/oil injection**, and lights off with a classic **pull start**—simple, confident, and ready when you are.
Power meets control through a **CVT** setup driven by belt, with a **P-22 / TEAM LWT clutch** package that’s all about keeping the ride responsive as conditions change. And when the mountain trail tightens up or you need to back out of a tricky spot, **reverse** is there—because sometimes the smartest move is the one that doesn’t involve wrestling 437 lbs of purpose-built attitude by hand.
This PRO-RMK is built on the **MATRYX aluminum frame**, designed for that planted-but-playful mountain feel. At **126.7 inches long** and **43.4 inches wide**, it’s sized to thread through trees and roll onto edge without feeling twitchy. The ski stance adjusts from **36 to 38 inches**, so you can dial in how you want it to behave—nimble and quick to transition, or a bit more settled when you’re reading unpredictable snow.
Up front, the **RMK® React™ independent A-arm** suspension offers **9 inches** of travel, paired with **Walker Evans Racing (WER®) adjustable gas shocks with remote reservoirs**. Out back, the **PRO-RMK rear suspension** delivers **16 inches** of travel with **two rear shocks**, also WER® remote-reservoir adjustables—plus a matching center shock. In other words: this sled is set up for riders who want to tune their ride, not just survive it. When the snow gets choppy, when landings get real, or when the day turns into a marathon, you’ve got the damping and adjustability to keep pushing.
The track is pure mountain intent: a **Series 8** at **155 x 15 inches** with **2.75-inch lugs**—the kind of bite that helps you claw forward when the climb turns soft and steep. Steering comes via **ProTaper™ handlebars** with manual control, and your hands get treated right with **heated, adjustable grips**—because cold fingers shouldn’t be the reason you call it early. Up front, **Gripper® skis** with **carbide skags** help keep the nose tracking when you need precision instead of guesswork.
It’s not all brute force, either. The cockpit keeps things modern and connected with **RIDE COMMAND™ GPS**, **Bluetooth® audio**, and **mobile app instrumentation**—so you can keep tabs on your ride and stay oriented when the world turns into a white horizon. You also get clear **gauge-based fuel level and temperature warnings**, and a **tinted, low LED** setup that looks sharp and stays functional when visibility isn’t playing nice.
Finish it off with a **one-piece vinyl seat**, skid-resistant running boards, practical guards (belt and snow), and a mountain-ready attitude that feels like it was built for the exact moment you see an untouched line and think, “Yeah… that’s mine.” The **** colorway just seals the deal—bold, clean, and perfectly at home in the high country.
