Meet the 2027 Polaris Patriot 9R RMK® SPS 155 ES in ****—a mountain sled that looks ready to misbehave before you even thumb the throttle. The stance is lean, the profile is low, and the whole machine has that “point me uphill” posture that makes parking-lot talk feel like a pre-ride warmup.
At the heart of it is Polaris’ **Patriot 9R** powerplant: a **liquid-cooled**, **2-cylinder**, **2-stroke** horizontal in-line built around an **899cc** displacement (88 mm bore x 74 mm stroke) and fed by **fuel injection** with **gas / oil injected** fueling. It’s designed for the kind of response you want when the snow turns deep and the line gets technical—clean delivery on **regular** fuel, a **single** exhaust, and that unmistakable two-stroke attitude that feels eager the moment you squeeze the **thumb throttle**. When it’s time to get moving, you’re on a **pull** starter, and the drivetrain keeps things simple and effective with a **CVT** and **belt** drive. Need to back out of a bad idea? **Reverse** is there.
The chassis is built on the **MATRYX** aluminum frame, keeping things strong without feeling bulky. With a **dry weight of 445 lbs**, it lands in that sweet spot where it feels planted when you want stability, but still light enough to throw around when the terrain demands a quick change of plans. Dimensions back up the mountain focus: **126.7 inches long**, **43.4 inches wide**, and **53 inches tall**, with a ski stance that adjusts between **36 and 38 inches**—so you can tailor the feel to your riding style and conditions. There’s also an **11-gallon** fuel capacity to keep you out longer when the snow is good and the daylight disappears too fast.
Up front, the sled runs an **RMK® React™** **independent A-arm** suspension with **9 inches** of travel, paired with **WER® Velocity** adjustable gas shocks with remote reservoirs. Out back, the **RMK® KHAOS®** suspension delivers **16 inches** of travel and uses **two rear shocks**, with a **WER® Velocity** center shock as well—again, adjustable and remote-reservoir equipped. The result is a setup that’s ready for everything from quick, precise inputs to bigger compressions when the mountain decides to test your commitment. Adjustments are handled via **shock mounted adjustment**, keeping tuning practical when you’re dialing things in.
The snow-contact pieces are all about control. The sled rides on **Gripper®** plastic skis with **carbide** skags, and braking is handled by an **RMK® hydraulic disc** rear brake. Underneath, a **Series 8** track lays down serious footprint: **155 inches** long, **15 inches** wide, with **2.75-inch** lugs built to claw for drive in deep snow. It’s a single-track setup, because that’s all you need when it’s the right track.
Inside the cockpit, it’s straightforward and purpose-built: a **one-piece vinyl** seat for a single rider, **rubber** grips with **adjustable heated hand grips** for the driver, and a **ProTaper™** handlebar-controlled manual steering setup that feels natural when you’re working the sled through trees or sidehilling across a face. Practical touches like a **belt guard**, **snow guard**, **skid resistant** running boards, and warning cues for **temperature** (light) and **fuel level** (gauge) keep the ride focused. Lighting is **LED** with a **tinted** lens and a **low** height—clean, modern, and ready for those late-day exits.
And in ****, this RMK® doesn’t just blend into the mountains—it looks like it belongs there, waiting for the next line and daring you to pick the steeper one.
