2025 Polaris® 850 RMK KHAOS 155 – Storm Gray / Indy Red
All-mountain chaos with purpose. The 2025 RMK Khaos is wild, light, and playful—delivering unmatched fun across technical terrain. Engine options, advanced suspension, and bold upgrades for 2025 make this sled ready to float, fly, and thrill in any snow conditions.
Lighter and Wilder for 2025
Up to 6.5 lbs. lighter with a redesigned throttle, lower seat, enhanced running board clean-out, and a lightweight headlight—amplifying agility and control.
Matryx RMK Platform
Narrow seat, tank, and console give you unmatched sled connection and maneuverability, with less drag for deep snow carving.
Rear Suspension That Floats
Playful geometry delivers transfer and traction for that signature Khaos float. Available in 146", 155", and 165" lengths.
Power Options That Rip
Choose your edge: the legendary Patriot 850, ultra-responsive Patriot 9R, or factory-turbocharged Patriot Boost.
Slash Tunnel & Rider Interface
Slashed tunnel design and advanced interface reduce drag and deliver agile, confident control.
QuickDrive System
Industry’s lightest drive system with low inertia for lightning-fast throttle response. Choose Series 9 or Series 8 track based on terrain.
React Suspension
36"-38" adjustable stance with sway bar and forged a-arms delivers predictable steering and confidence in every carve.
Walker Evans Hi-Lo Shocks
Extreme terrain ready with premium adjustability. Remote reservoirs and hi/lo compression controls let you tune for the mountain.
