The 2025 Polaris BOOST RMK Khaos 155 Snowmobile combines turbocharged power with unmatched agility to deliver an exhilarating deep-snow experience. Designed for riders who thrive on performance, this sled excels in steep climbs, technical terrain, and powder-filled valleys.
Polaris built the BOOST RMK Khaos with a lightweight aluminum frame and a short, tapered tunnel that reduces drag while shedding snow quickly. This thoughtful design improves responsiveness and allows riders to carve precisely through demanding backcountry conditions.
At the heart of this sled lies the Patriot Boost 850 Turbo engine, engineered for explosive acceleration and fast throttle response. Paired with the P-22 / TEAM clutch system and CVT transmission, it ensures smooth power delivery across all conditions. Moreover, the 155″ Series 8 track with 2.75″ lugs enhances traction and flotation, keeping you in control on the steepest slopes.
Although built for performance, the BOOST RMK Khaos includes convenient features such as reverse gear, LED lighting, and glove box storage. With its 11-gallon fuel tank, riders can explore further, and its 442 lb dry weight offers stability while maintaining agility.
The Independent A-Arm front suspension with 9.5″ travel delivers precision steering and absorbs bumps effectively. The rear suspension with 16″ travel ensures smooth landings and stability in rough terrain. Additionally, the adjustable ski stance from 36 to 38 inches lets riders fine-tune handling for different snow conditions. Heated grips and a standard windshield enhance comfort during long mountain sessions.
