2027 Polaris 650 RMK® SP 155

Meet the 2027 Polaris 650 RMK® SP 155, a mountain sled that looks as ready for the treeline as it feels—and this one shows up in , a scheme that fits right in with the RMK SP’s no-nonsense, go-anywhere attitude while still standing out when the snow starts flying.



At the heart of this mountain machine is the Patriot™ 650: a liquid-cooled, 2-cylinder, 2-stroke that’s built to respond fast and keep pulling when the climb gets serious. With electronic fuel injection and gas/oil injection, it’s designed to keep things crisp and consistent when you’re threading through timber or getting back on the throttle after a quick sidehill correction. And when you’re ready to turn fresh powder into a launch ramp, the added shove of turbocharging helps make every squeeze of the thumb throttle feel like a clear invitation to aim higher.



Getting that power to the snow is a CVT transmission with belt drive, paired with a P-85 / TEAM LWT clutch setup—the kind of drivetrain feel mountain riders appreciate when conditions are changing by the minute and you want smooth, usable drive instead of drama. There’s also reverse, because even the best lines sometimes need a quick reset (and it’s a lot nicer to back out cleanly than to wrestle your way out).



The RMK SP 155 is sized for the terrain it’s meant to play in. With a 155-inch Series 8 track that’s 15 inches wide and wears 2.75-inch lugs, it’s made to bite, paddle, and stay on top when the snow gets deep and the slope gets steep. That track works with a chassis that’s built with purpose: an aluminum MATRYX frame that keeps things strong and responsive, without feeling bulky when you’re transitioning from carve to carve. At a listed dry weight of 446 lbs, it stays in that sweet spot where the sled feels substantial under power but still eager to be guided by body English.



Up front, the RMK® React™ independent A-arm suspension brings 9 inches of travel, tuned for the kind of unpredictable hits and quick direction changes mountain riding loves to serve up. Out back, the RMK rear suspension delivers a big 16 inches of travel with two rear shocks, helping you keep momentum when the terrain turns choppy or when the landing isn’t quite as plush as you planned. With Polaris IFP adjustable gas shocks (front, rear, and center) and shock-mounted adjustment, you can dial the feel toward your kind of day—whether that’s playful and poppy or planted and precise.



Details matter when you’re hours into a ride and the temperature drops. This sled keeps your hands happy with heated, adjustable driver grips, and it keeps key info easy to read with LED lighting and practical alerts like a temperature warning light and a fuel gauge. You’ve also got an 11-gallon fuel capacity for longer routes, plus rider-focused protection like a belt guard and snow guard.



Steering feels direct thanks to ProTaper™ handlebars with manual steering, and the front end’s contact with the snow is handled by Gripper® plastic skis matched with carbide skags—a combination meant to help keep your line when you’re picking your way across variable surfaces. Add a hydraulic disc rear brake with RMK branding, and you’ve got confident control when it’s time to scrub speed before the next move.



From the low, one-piece vinyl seat to the skid-resistant running boards, the 2027 650 RMK SP 155 is built for the rider who measures a good day in vertical feet and fresh tracks. In , it’s a mountain weapon that looks the part—then backs it up the moment the trail disappears and the real ride begins.
