Features

Additional Features

  • AXYS PERFORMANCE SEAT: The AXYS Performance Seat provides the ideal mix of comfort and support for seated riders, and its design provides standing riders with the greatest room to move.
  • LED LIGHTS: All models built on the AXYS platform feature standard LED headlights to deliver the industry's best lighting that is 80% brighter than incandescent lighting.
  • MESSAGECENTER GAUGE: Informative and easy to read, this gauge keeps a rider aware of sled operating conditions and provides a wealth of additional data.
  • GRIPPER SKIS: Skis deliver flotation in deep snow plus smooth, easy handling on-trail. The top surface features serrated edges for boot traction in deep snow.

Immediate Response

  • POWDERTRAC™ HYBRID RUNNING BOARDS: The PowderTrac™ Hybrid Running Boards offer optimized design with 56% open space for maximum snow clean out while maintaining extreme strength.
  • LIGHTWEIGHT: Polaris snowmobiles are the lightest sleds on the mountain. They have always been light and rigid with added strength and durability while reducing weight on the RMK AXYS platform. Providing riders with instantaneous lift, Polaris sleds help riders get up on top of the snow faster.

Instantaneous Lift

  • AXYS CHASSIS: The raised AXYS chassis increases clearance and reduces drag to keep you on top of the snow. It is purpose-built for mountain riding and allows for improved sidehilling, faster and easier climbing, and instantaneous lift allowing the sled to pop onto the snow faster. The aluminum over structure is lightweight and durable for all types of riding. Taller spindles increase clearance to reduce drag.
  • 15 X 146 X 2.25" SERIES 2.5 TRACK: Delivers outstanding traction both on- and off-trail with excellent durability.
  • LIBERTY ENGINE CHOICES FOR EVERY RIDER: Built to integrate seamlessly with the lightweight and agile Polaris chassis, Liberty engines feature class-leading power-to-weight ratios and set a new benchmark for ultimate performance with our complete line-up of powerful options.
  • IGX REAR SUSPENSION: The IGX - Ideal Geometry Xover - Rear Suspension delivers a smooth ride and outstanding hauling on all terrain and in all snow depths and conditions. It's designed for minimal bottoming and drag off-trail.
  • CHAINCASE DRIVE SYSTEM: The SKS 146 uses the tried and true Polaris chaincase drive system to deliver the perfect combination of strength and performance in all snow and riding conditions.
  • WER® SHOCKS: The WER® Compression Adjustable Piggyback Shocks are more tune-able and allow you to adjust compression to suit your riding styles and the day's condition.

Rider Balanced Control

  • AXYS BODY PANEL DESIGN: The compact AXYS body design provides the industry's highest lean angle to keep the weight on the skis and track - even in the meadows - and it minimizes paneling out. Paneling out compromises control and can occur on steep inclines and while carving.
  • NARROW, ADJUSTABLE FRONT END: Narrow 39" - 41" adjustable front end is ideal for setting up for more stability or ultimate performance while tree-riding or boondocking.
  • FORGED, ALUMINUM A-ARMS: The efficient one-piece design reduces weight and improves optimal strength, suspension performance, and sled handling. The design reduces unspring mass, resulting in improved ride quality and increased maneuverability.
