The 2025 Polaris Boost RMK KHAOS 155 represents the pinnacle of backcountry snowmobiling performance, built for riders who crave agility, response, and high-octane adrenaline in deep powder conditions. With its factory-installed turbocharged Patriot Boost engine, this sled delivers instant power and incredible throttle response at any elevation, ensuring you're never left wanting more in demanding terrain.

The lightweight, purpose-built MATRYX RMK platform continues to be a standout, offering unmatched control, rider-forward ergonomics, and a chassis that’s both durable and flickable. The 155” track length, paired with Polaris's proven suspension systems and the KHAOS-specific geometry, brings a playful, dynamic ride feel that excels in technical terrain and makes sidehilling, carving, and boondocking not just possible—but exhilarating.

Polaris has also paid attention to the small things: improved cooling, optimized weight distribution, and easy maintenance access—all making this machine not just powerful, but practical for serious riders. Whether you're launching off a cornice, carving steep tree lines, or just exploring the deepest stashes, the 2025 Boost RMK KHAOS 155 ensures you can ride harder, longer, and with more confidence than ever before.
