2027 Polaris Patriot Boost RMK® KHAOS® 155

Meet the 2027 Polaris Patriot Boost RMK® KHAOS® 155 in —a mountain sled that looks like it was built to leave the trailhead behind and go pick a fight with the steepest line you can see.



At the heart of it is the Patriot™ Boost powerplant: an 840cc, liquid-cooled, 2-cylinder, 2-stroke turbocharged engine with fuel injection and gas / oil injection, tuned to deliver punchy response when the snow gets deep and the climb gets serious. It’s a pull-start setup that runs on regular fuel, and the power flows through a CVT with belt drive, plus reverse for the moments when your “that’ll work” parking spot turns into a “maybe not” situation.



This KHAOS rides on the MATRYX aluminum frame, keeping things purpose-built for mountain movement, while the RMK® React™ independent A-arm front suspension and RMK® KHAOS® rear suspension bring the travel to match the terrain—9 inches up front and 16 inches out back. With WER® Velocity adjustable gas shocks with remote reservoirs (front, rear, and center), you’ve got the tools to dial it in for your kind of day—whether that’s playful sidehills, quick transitions, or long pull-ups that test your throttle control.



Out back, the Series 8 track stretches 155 inches long and 15 inches wide with 2.75-inch lugs, built to dig, bite, and keep driving when the snow turns bottomless. Up front, Gripper® skis with carbide skags help keep the nose honest when the terrain gets choppy or the approach gets firm.



Inside the cockpit, it’s all about ride time: a one-piece vinyl seat, adjustable heated grips, thumb throttle, and LED lighting with a tinted lens. Add RIDE COMMAND™ GPS, gauge warnings for temperature and fuel level, plus Bluetooth® audio and mobile app instrumentation, and you’ve got a mountain machine that’s as connected as it is capable.



In , this RMK® KHAOS® 155 doesn’t just show up—it shows off, then disappears into the powder.
