Meet the 2027 Polaris Patriot Boost RMK® KHAOS® 155 in ****—a mountain sled that looks like it’s already halfway up the next face before you’ve even finished tightening your gloves. The KHAOS name isn’t subtle, and neither is the attitude: this machine is built for riders who see deep snow as an invitation, not an obstacle.
At the heart of it all is the **Patriot™ Boost** engine—an **840cc**, **liquid-cooled**, **2-cylinder**, **2-stroke** that’s **turbocharged** and **fuel injected**, with **reed valve** breathing and a **single exhaust** that keeps things clean and purposeful. It runs on **regular fuel**, uses **gas / oil injection**, and fires up the old-school-right way with a **pull starter**—because when you’re out in the mountains, simple and reliable just feels right. Power delivery is handled by a **continuously variable (CVT)** setup with **belt drive**, using the **P-22 / TEAM LWT clutching**, and yes—there’s **reverse** for those moments when your line choice gets “creative.”
The chassis is Polaris’ **MATRYX aluminum frame**, wrapped in durable **plastic bodywork**, and it feels sized perfectly for technical mountain terrain: about **126.7 inches long**, **43.4 inches wide**, and a **low-height** stance that keeps it feeling ready to sidehill, cut, and pivot. With a **dry weight of 442 lbs** and an **11-gallon** fuel tank, it’s built to stay playful while still giving you the range to keep exploring beyond the obvious lines.
Up front, the **RMK® React™ independent A-arm** suspension brings **9 inches of travel**, paired with **WER® Velocity adjustable gas shocks with remote reservoirs** (coil-over design) and **shock-mounted adjustment** so you can fine-tune for changing snow and speed. Out back, the **RMK® KHAOS® rear suspension** delivers a generous **16 inches of travel**, using **two rear shocks** plus a **WER® Velocity center shock**, all adjustable and all remote-reservoir-equipped—because big hits, quick transitions, and deep-snow landings are part of the plan, not a surprise.
Then there’s the business end: a **Series 8 track** measuring **155 inches** long and **15 inches** wide with a towering **2.75-inch lug height**—the kind of footprint that loves soft snow and rewards throttle confidence. Steering is handled through a **ProTaper™ handlebar** with **manual steering**, a **thumb throttle**, and **adjustable heated grips** (rubber, of course), so your hands stay comfortable when the climb gets long and the air gets sharp.
Details matter in the backcountry, and this sled comes ready with practical protection like a **belt guard** and **snow guard**, plus **skid-resistant** running boards for when you’re shifting your weight and dancing the sled across a hillside. The **Gripper® skis** (plastic) with **carbide skags** help keep your line honest when conditions get weird.
Inside the cockpit, it’s modern where it counts: **RIDE COMMAND™ GPS**, **LED** lighting with a **tinted** lens, and gauge-based warnings for **temperature** and **fuel level**. You also get **Bluetooth® audio** and **mobile app instrumentation**, turning the ride into an experience you can track, revisit, and plan again—because the only thing better than a good day in the mountains is knowing exactly how to top it next time.
Finished in ****, this RMK® KHAOS® doesn’t just blend into winter—it owns it. Point it at fresh snow, squeeze the thumb, and let “fun” take the shape of a climbing line.
