The 2025 Polaris Boost PRO RMK 155 is not just the next step in mountain snowmobile evolution—it’s the benchmark for where high-performance backcountry machines are headed. Combining Polaris’ proprietary Patriot Boost engine with a purpose-built chassis and suspension system, this sled offers an elite-level experience for riders who know how to push limits and thrive in technical terrain.

At its heart, the factory-installed turbocharged Patriot Boost engine delivers class-leading power with zero lag, offering crisp throttle response and consistent pull in all snow and elevation conditions. Unlike aftermarket setups or older turbo technologies, the Boost system is fully integrated and calibrated specifically for mountain use—resulting in a ride that feels powerful, predictable, and refined. From tree-filled climbs to wide-open alpine bowls, the Boost engine delivers usable power exactly when you need it.

What truly elevates the PRO RMK 155, though, is its ability to handle that power with finesse. Built on the MATRYX RMK chassis, the sled offers a narrow, lightweight platform that moves with the rider. Its ergonomic design—low seat, tapered tunnel, and snow-shedding bodywork—lets you transition from edge to edge with ease, perfect for quick corrections and technical line choices. The 155-inch track length, available in either Series 8 or Series 9 configurations, provides a versatile mix of float and flickability, making this sled ideal for experienced riders who want responsiveness without sacrificing traction in deep powder.
