2025 Polaris® Boost RMK KHAOS 155 Shadow Gray / Gloss Black

UNMATCHED FUN FACTOR IN ANY TERRAIN.

The RMK Khaos delivers a wild child attitude, dynamic and agile performance.

Features may include:

THE BEST MOUNTAIN SLED JUST GOT BETTER - AND EVEN LIGHTER

The RMK Khaos delivers transfer and traction for a wild ride. 2025 Boost and 9R RMK Khaos models are up to 6.5 lbs. lighter and have a redesigned throttle system, 1" lower seat, improved running board clean-out, and a lightweight headlight for improved connection and control to deliver the best RMK experience yet.

  • Rider First Design. Effortless Control.

The Matryx RMK platform includes a narrow seat, tank and console that provide improved rider connection to the sled while the narrow bodywork enables more agility and less drag in the snow. The new seat design and running boards further improves rider mobility on the sled while the new throttle system helps you feel connected to the sled on every ride.

  • Float. And Fly.

The RMK Khaos Rear Suspension features geometry that provides transfer and traction for light, playful handling, along with the best response and control in all riding zones. Available in 146, 155 and 165 lengths.

  • Choose Your Power.

Three engine choices from the Patriot Family to fit your riding style. Choose the legendary durability and relentless acceleration of the Patriot 850, or the Factory Mods… the ultra-responsive Patriot 9R or turbocharged Patriot Boost.

PURPOSE-BUILT RIDE & HANDLING FOR ALL-MOUNTAIN

When we build a sled, we build it to be the best sled for each unique riding style, not simply a different sticker or name. Every part is scrutinized to deliver what you need as a rider.

  • Ultimate Control

The RMK Matryx Slash platform features a next-level rider interface and slashed, tapered tunnel. Combined they deliver minimized drag and maximum control.

  • Lightning-Fast Response. Puts The Power Down.

QuickDrive is the lightest drive system in the industry and produces the lowest inertia for optimum response. Choose between the 325 Series 9 Track for instant traction and forward drive in deep snow or the 275 Series 8 track for versatility and traction in varying snow conditions.

  • Precise Steering. Confidence Inspiring.

The RMK React Suspension lets riders effortlessly initiate sidehills and experience less fatigue with the most predictable ride. It includes a 36"-38" stance, a sway bar designed for predictable handling, and forged a-arms and spindles optimized for strength and durability.

  • Big Time Shocks for Big Time Terrain.

Ultra-premium Walker Evans Hi-Lo Shocks are the best of the best in extreme mountain conditions. They feature remote reservoirs for increased oil capacity to ensure all-day performance and durability, along with high and low-speed compression adjustment to dial in the ride.

INDUSTRY-LEADING TECHNOLOGY

Polaris sleds lead the way in technology that enhances your ride. Technology built to help you plan rides, track your group, keep your sled cool in tough conditions, and see your way from dusk til dawn.

  • Built to Stay Cool and Light.

The shortened centralized cooling system on the RMK Matryx Slash platform features reduced dry weight and delivers improved cooling capability while reducing snow and ice build up. Reversible scratchers will help to keep your Patriot power running within spec.
