Features

Instantaneous Lift

  • AXYS® CHASSIS: The AXYS® chassis structure and design makes it possible to change the rider positioning, centralize vehicle mass, redesign the rear suspension, add more power, remove weight, and evolve the rider’s riding experience. In short, it is the key to delivering rider-balanced control, unrivaled acceleration, and rider-centric comfort.
  • RIDER BALANCED CONTROL: Rider Balanced Control gives the rider flatter cornering without sacrificing the fun factor, more precise handling in all conditions, better control in big bumps and chatter bumps.
  • RIDER BALANCED POSITIONING: On the AXYS® chassis, the rider is moved forward to a more balanced position. The rider’s hands are moved 4.5 in. forward, the feet are 2 in. forward, the knees are 4.5 in. forward, and the seat is 4.5 in. forward. In the neutral riding position, the AXYS® platform provides bite for flatter, positive cornering. When the trail gets rough or the rider jumps off into the powder, rider balance enables the rider to move back and make the front end light to climb up on top of the snow or the moguls.
  • PRO-XC™ REAR SUSPENSION: The completely redesigned geometry of the PRO-XC progressive-rate rear suspension is optimized for the best performance and Rider-Balanced Control. Through innovative Polaris engineering and construction, the suspension is both lighter and stronger, featuring lightweight, forged aluminum rear crank and a completely redesigned crank and pivot. The front torque arm was moved rearward to control pitch, increase travel, and improve the rail profile.
  • ACTIVE PITCH CONTROL™: The PRO-XC™ suspension delivers Active Pitch Control™ which controls the pitch by suspension geometry and not simply by a high spring rate. This makes the sled less sensitive to adjustment while allowing optimal weight transfer.

Rider Centric Comfort

  • AXYS® PERFORMANCE SEAT: The AXYS Performance seat utilizes a high-performance seat foam, and the seat design is narrower in front to provide greater maneuverability. The seat is lighter without compromising comfort. Improved ergonomics and stability. Seat top features a gripper material that helps keep the rider in place.
  • POLARIS INTERACTIVE DIGITAL DISPLAY: Exclusively from Polaris - the most advanced instrumentation in snowmobiling. This 4.3 in. high resolution, full color, LCD digital display provides a rider with information including: 1) Sled performance - Speedometer, tachometer, dual tripmeters, average speed, max speed, engine/trip hours & odometer. 2) Sled operating conditions - Coolant temperature, diagnostics & maintenance warnings. 3) Riding conditions - Air temperature, time of day in 12 or 24-hour clock format. 4) Bluetooth™ functionality - Enables the gauge to communicate with the rider’s cell phone and provide notification of incoming calls or texts. Displays phone battery & signal strength. 5) GPS/Mapping Capability - A compass is standard, & full-featured GPS can be installed to provide directions & information about services such as fuel, restaurants, lodging & Polaris dealerships. Customize the GPS to operate with North Up or Course Up navigation depending on your preference. 6) Ride Planning Feature enables you to plan a ride using Ride Command, save it as a GPX file, and transfer it to the display through the USB interface.
  • LEFT-HAND CONTROLS: The left-hand controls feature improved ergonomics, updated styling, and enhanced hand and thumb warmer control. The controls are easy to operate with gloves on, and have an improved tactile feel.
  • LED LIGHTS: All models built on the AXYS® platform feature standard LED headlights. LED headlights deliver the industry’s best lighting - nearly 1 lb. lighter and high beams are 80% brighter than incandescent lighting. Color temperature or output of the lights (the “whiteness” of light, reported in Kelvin) is 5,000 K, closely matching daylight. LED headlights last the entire lifetime of the sled. A major durability enhancement over traditional incandescent headlights which experience filament burn out. For constant visibility and enhanced safety, the low beams remain on at all times. Even when the high beam is activated, there is never a period of no light.
  • WIND PROTECTION: The hood and windshield designs produce significantly enhanced wind protection for a rider, and the foil on the side panels further enhances protection.
  • INTEGRATED STORAGE: Storage was designed and developed right along with the AXYS platform, so it installs securely and features seamless, integrated styling that matches the sled’s design lines. Compression-molded materials provide semi-rigid storage and enhanced styling. Sturdier zippers provide better cargo security and protection. Installs without tools.
  • PREMIUM FIT & FINISH: Interfacing surfaces between body panels and components are shorter for minimized gaps. Interfaces are strategically located in recessed areas. Styling of storage elements results in clean, integrated lines. Components are engineered for functionality and styled for the best styling.

Unrivaled Acceleration

  • LIGHTWEIGHT: When developing the AXYS® platform, Polaris engineers minimized weight throughout the sled without compromising strength.
  • POLARIS® 850 PATRIOT™ ENGINE: The most powerful Polaris® snowmobile engine ever, building on 25 years of legendary liberty® engine heritage, creates an all-new benchmark for durability, acceleration, and response. Industry-leading power-to-weight ratio and unmatched throttle response.
