Features

Rider Balanced Control

  • AXYS CHASSIS: The AXYS chassis design is the key to delivering rider balanced control through the right rider positioning and centralized vehicle mass. The rider's hand position is moved 4.5" forward, the feet position is 2" forward, the knee position is 4.5" forward, and the seat is 4.5" forward. This means more bite for flatter cornering when in the neutral riding position and a lighter front end for climbing on top of the snow or the moguls when the rider shifts to the back of the sled.
  • PRO-XC REAR SUSPENSION WITH POLARIS RACE TECHNOLOGY: The PRO-XC progressive-rate rear suspension is optimized for the best performance and control. Through innovative Polaris engineering, the suspension is both lighter and stronger. The front torque arm is rearward to control pitch, increase travel, and improve the rail profile. To increase durability and strength for extreme performance, the Switchback XCR features additional race-inspired components including: Chromoly Rear Pivot, FTS Mount, Solid Jackshaft, Chromoly Front Torque Arm, Reinforced Rail Beams, Solid Bogie Wheels, and IQR Rear Axle Wheels.
  • 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.
  • POLARIS RACE TECHNOLOGY BRAKE SYSTEM: Delivers outstanding performance and unparalleled durability. The race rotor provides increased surface area that effectively absorbs heat from brake pads for more consistent performance and even pad wear. Brake Scoop offers increased cooling while the Type 81 Brake Pads withstand higher temperatures associated with higher speeds.
  • PRO-STEER SKIS: The PRO-STEER ski features a reshaped keel and shortened skag for reduced steering effort. Redesigned ribs atop the ski increase stiffness for more precise steering, and bosses added atop the ribs provide traction to prevent slipping when a rider steps on the ski in deep snow.

Rider-Centric Comfort

  • AXYS PERFORMANCE SEAT: The high-performance seat foam and narrow front design of the AXYS Performance seat delivers greater maneuverability. It's lighter without compromising comfort, offers improved ergonomics and stability, and its gripper top material helps keep the rider in place.
  • WER® SHOCKS: WER® Compression Adjustable Piggyback Needle Shocks with Switchback XCR valving are more tune-able and allow you to adjust compression to suit your riding styles and the day's conditions. They are the most durable in extremely rough terrain at high speeds.
  • POLARIS MESSAGECENTER GAUGE: Center GaugeKeeps a rider aware of sled operating conditions and other important information. Large buttons can be operated with gloved hands and the brightly lit display is easily readable in all light conditions.
  • LEFT-HAND CONTROLS: The left-hand controls feature improved ergonomics and enhanced hand and thumb warmed control. The controls are easily operated with gloves on.
  • LED LIGHTS: All AXYS models feature standard LED headlights for the industry's best lighting that last the entire lifetime of the sled. Nearly 1 lb. lighter with high beams 80% brighter than incandescent lighting. Low beams remain on at all times for constant visibility and enhanced safety.
  • WIND PROTECTION: The hood and windshield design produce significantly enhanced wind protection for a rider, and the foil on the side panels further enhances protection.

Unrivaled Acceleration

  • LIGHTWEIGHT DESIGN: When developing the AXYS platform, our engineers minimized weight throughout the sled without compromising strength or 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.
