2027 Polaris BOOST RMK KHAOS 155

2027 Polaris Patriot Boost RMK Khaos 155 White Lightning / Velocity Blue

If your idea of a great snow day involves deep snow, steep climbs, technical terrain, and a sled that responds instantly when you move your weight, the 2027 Polaris Patriot Boost RMK Khaos 155 is built for that kind of riding. This high-elevation configuration combines the turbocharged Patriot Boost engine with a 155-inch Series 9 track featuring 3.25-inch lugs, RMK Khaos suspension, Walker Evans Racing Velocity Hi-Lo shocks, and the lightweight RMK chassis. The result is a mountain sled focused on lift, traction, quick response, and rider-controlled handling.

Finished in White Lightning and Velocity Blue with a black tunnel and Velocity Blue rails, this particular sled also features manual start with high-elevation clutching, a wind deflector, standard 5-inch bar, and 7S Display. It is a focused configuration for riders who know what they want from a high-performance mountain snowmobile.

Patriot Boost Power for High-Elevation Mountain Riding

The Patriot Boost is designed around turbocharged power and strong response in mountain conditions. With 840cc displacement, liquid cooling, Cleanfire fuel injection with auxiliary injection, and Polaris Patriot 3DS ignition, the engine package delivers the power this chassis needs when the terrain gets steep and the snow gets deep.

• 840cc liquid-cooled Patriot Boost two-cylinder engine
• Turbocharged power designed for performance at elevation
• Cleanfire and auxiliary fuel injection
• Patriot 3DS ignition system
• Single three-stage VES exhaust
• Manual start configuration keeps the package focused and avoids the added hardware of electric start

155-Inch Series 9 Track Built for Deep Snow

The 15 x 155 x 3.25-inch Series 9 track is a major part of this sled's mountain-focused setup. The taller 3.25-inch lugs are designed to deliver traction and forward drive when you're working through deep snow, climbing or looking for lift. Polaris specifically positions the 325 Series 9 track for deep-snow traction and forward drive.

• 155-inch track length for mountain flotation and traction
• 3.25-inch Series 9 lug profile
• 15-inch track width
• Deep-snow-oriented traction characteristics
• QuickDrive drive system helps keep rotating mass low for responsive handling

RMK Khaos Suspension for Aggressive Terrain

The RMK Khaos rear suspension is designed around an active, playful mountain riding style. With 9 inches of front travel and 16 inches of rear travel, the suspension gives the sled room to work through uneven terrain while maintaining the agile feel Khaos riders look for.

• RMK React front suspension
• RMK Khaos rear suspension
• 9 inches of front suspension travel
• 16 inches of rear suspension travel
• Walker Evans Racing Velocity Hi-Lo shocks
• Hi-Lo shock adjustment gives experienced riders more ability to tune the sled to terrain and riding conditions

Narrow, Agile Mountain Chassis

The RMK platform is designed to make technical mountain riding less of a fight and more about rider input. A narrow 43.4-inch overall width, adjustable 36-to-38-inch ski stance, and lightweight construction help the sled respond when you want to carve, sidehill, lift the skis, or change direction.

• 36-to-38-inch adjustable ski stance
• Narrow RMK chassis designed for maneuverability
• Tapered tunnel helps maintain an agile mountain profile
• Lightweight construction with an estimated dry weight of 442 pounds
• RMK running boards provide a platform for moving your body around the sled in technical terrain

Rider-Focused Controls and Technology

This configuration keeps the cockpit centered on the information and controls a mountain rider actually uses. The 7S Display provides access to key vehicle information, while the standard 5-inch ProTaper handlebar maintains a familiar control layout for active off-trail riding.

• 7S Display
• Standard 5-inch ProTaper handlebar
• High and low hand and thumb warmers
• PERC electronic reverse
• Electronic fuel gauge
• Wind deflector
• Manual start
• High-elevation clutching

White Lightning and Velocity Blue Mountain Package

This particular sled has a purposeful appearance that matches its performance-focused equipment. White Lightning bodywork is paired with Velocity Blue rails and a black tunnel, giving the machine a distinctive look without taking attention away from the hardware underneath.

• White Lightning / Velocity Blue finish
• Black tunnel
• Velocity Blue rails
• Walker Evans Velocity Hi-Lo shocks
• 155 x 3.25 Series 9 track
• Wind deflector
• Standard bar
• 7S Display

Built for Riders Who Want More From the Mountain

The Patriot Boost RMK Khaos 155 is aimed at experienced mountain riders who want a playful, responsive sled with serious deep-snow capability. The combination of turbocharged Patriot Boost power, a 155-inch Series 9 track, Khaos rear suspension, adjustable Walker Evans Velocity Hi-Lo shocks, and the RMK chassis creates a package centered on technical riding and deep-snow performance.

This is the kind of snowmobile that makes sense when your riding goes well beyond groomed trails. If your season revolves around powder, climbs, sidehills, tree riding, and technical terrain, the 2027 Patriot Boost RMK Khaos 155 gives you the equipment to make those days count.
