2018 Polaris® 800 PRO-RMK® 155 3.0 Series 7 SnowCheck ES

The 2018 Polaris 800 PRO-RMK 155 3.0 Series 7 stands as a benchmark for lightweight, agile mountain snowmobiles that deliver exceptional performance in deep snow and technical terrain. Designed around Polaris’ AXYS platform and complemented by the lightweight Series 7 3.0" track, this sled brings a level of precision and responsiveness that appeals to aggressive backcountry riders. Its 800 Cleanfire H.O. engine provides dependable power and snappy throttle response, while the mountain-specific geometry and centralized mass design translate to excellent balance and control on steep sidehills, tight trees, and variable snow conditions.

The 155" length and 3.0" lugs strike a solid balance between floatation and maneuverability, helping riders maintain momentum in deep powder without compromising the sled’s ability to initiate quick direction changes or carve tightly. Polaris’ attention to detail in chassis design, including the narrow body panels, rigid rear suspension, and ergonomically optimized cockpit, results in a machine that feels almost intuitive to ride. Whether you're a seasoned mountain veteran or an intermediate rider looking to build confidence, the PRO-RMK 155 provides the kind of predictable handling and rugged dependability needed for serious backcountry adventures.

Overall, the 2018 Polaris 800 PRO-RMK 155 3.0 Series 7 remains a respected choice among mountain sleds—even years after its release—thanks to its lightweight build, proven powerplant, and rider-focused design. It's a snowmobile that doesn’t just get you to the top; it makes the climb more fun, more controlled, and more capable than ever before.
