2025 Polaris 850 RMK KHAOS 155

The 2025 Polaris 850 RMK Khaos 155 is a single-rider mountain snowmobile designed for deep snow and active backcountry riding. Its 840 cc Patriot engine and QuickDrive2 system provide a lightweight powertrain for climbing, sidehilling and moving through unpacked terrain. The 155-inch track balances deep-snow flotation with a more responsive feel than longer mountain configurations. Its Khaos rear suspension is intended for riders who prefer a playful and manoeuvrable mountain chassis. It suits experienced riders looking for an all-mountain sled that remains manageable in tighter terrain.
