The 2025 Polaris 850 RMK Khaos 155 Snowmobile gives riders agility, power, and a playful riding style in deep snow. With its lightweight chassis and Patriot 850 engine, it combines strength with responsiveness to master steep mountain terrain.
Polaris built the Khaos on a lightweight aluminum frame with a short, tapered tunnel. This design reduces drag, sheds snow quickly, and improves maneuverability. In addition, the compact structure lets riders carve with precision while maintaining stability in challenging conditions.
The Patriot 850cc liquid-cooled engine delivers strong throttle response and reliable power. The P-85 / TEAM clutch system works with the CVT transmission to provide smooth acceleration and consistent performance. Furthermore, the 155″ Series 8 track with 2.75″ lugs grips firmly and floats confidently, helping riders climb aggressively and maneuver with ease.
Although designed for performance, the Khaos also adds practical features. Riders can rely on reverse gear, LED lighting, and glove box storage for everyday use. Moreover, the 11-gallon fuel tank supports long backcountry trips, and the 426 lb dry weight keeps the sled nimble in tight or steep terrain.
The Independent A-Arm front suspension with 9.5″ travel absorbs bumps and sharp impacts, giving precise steering. Meanwhile, the rear suspension with 16″ travel stabilizes performance on descents and rough trails. Riders can also adjust the ski stance from 36–38 inches to adapt handling to conditions. Comfort features such as heated grips and a standard windshield keep riders focused and comfortable during long days in the snow.
