The 2025 Polaris BOOST RMK Khaos 155 Snowmobile raises the bar for deep-snow performance with turbocharged power and playful handling. Designed for riders who want unmatched acceleration and agility, it combines the strength of the Patriot Boost engine with a lightweight chassis and precision suspension.
The RMK Khaos features a lightweight aluminum frame with a short, tapered tunnel that minimizes drag and sheds snow quickly. This streamlined design enhances maneuverability and allows riders to carve smoothly through steep and technical terrain.
At the heart of the sled is the Patriot Boost 850 Turbo engine, delivering explosive acceleration and strong throttle response. The P-22 / TEAM clutch system and CVT transmission provide smooth, consistent power transfer. Furthermore, the 155″ Series 8 track with 2.75″ lugs ensures maximum traction and flotation, allowing riders to dominate deep powder and steep climbs.
Although performance-driven, the BOOST RMK Khaos offers practical features. Riders benefit from reverse gear, LED headlights, and glove box storage. Additionally, the 11-gallon fuel tank supports long backcountry adventures, while the 442 lb dry weight ensures stability without compromising agility.
The Independent A-Arm front suspension with 9.5″ travel enhances steering precision and absorbs impacts with ease. The rear suspension with 16″ travel increases comfort and control across rough terrain. Riders can also adjust the ski stance between 36 and 38 inches for tailored handling. Comfort-focused features like heated grips and a standard windshield keep riders prepared for long days in the snow.
