2019 Polaris 850 Switchback Assault 144 SnowCheck Select

Rider Balanced Control

• AXYS® CHASSIS: The AXYS chassis for the 144 platform is light and strong, offering rider balanced characteristics critical for the 50/50 rider. The rider is moved into a balanced position on the sled so it rides flat through the corners. 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.
• IGX: A core element to the AXYS 144 platform is the IGX 144 uncoupled rear suspension, which offers the ultimate blend of durability and strength. The IGX 144 rear suspension provides RMK-inspired off-trail agility and balance with a drastically improved on-trail ride. Pitch is controlled through geometry in this rear suspension. And with 43% more front torque arm travel, this sled features reduced bottoming and less drag off-trail. An optimized, lighter, reinforced tipped rail beam design gives the sled a nimble feel.
• 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. 1) Designed to serve the needs of riders on- & off-trail. 2) Efficient design delivers maximum strength & snow clean-out with 56% open space. 3) Front is wide & flat for foot comfort & stability; rear has tapered, dual-angle design for mobility & snow clearance

• 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 5000K, 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. 1) Compression-molded materials provide semi-rigid storage and enhanced styling. 2) Sturdier zippers provide better cargo security and protection. 3) Installs without tools.
• PREMIUM FIT & FINISH: Interfacing surfaces between body panels and components are shorter for minimized gaps. 1) Interfaces are strategically located in recessed areas. 2) Styling of storage elements results in clean, integrated lines. 3) Components are engineered for functionality and styled for the best styling.
• TRACKER OPTIONS: Various track options are available for the Switchback® Assault® that let a rider customize the sled to suit their personal riding style. Track options include: Cobra 1.35” track for superior traction and control on soft, loose and unpacked snow; Cobra 1.6” track for smooth performance on groomed trails and excellent performance on soft, loose snow of ungroomed trails; and 2.0 Series 4 track is the standard in 2" deep snow tracks for 50/50 riders.
