2021 Polaris 850 Switchback Assault 144 Factory Choice

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.
• IGX 144 REAR SUSPENSION: The IGX 144 rear suspension offers the ultimate blend of durability and strength. Pitch is controlled through geometry 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® RUNNING BOARDS: The PowderTrac® Running Boards offer an optimized design with 56% open space for maximum snow clean out while maintaining extreme strength. Perfect for on- and off-trail riding.

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.
• POLARIS MESSAGECENTER GAUGE: Keeps 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.
• PROTAPER HANDLEBARS: ProTaper handlebars are aluminum and feature a flat design with integrated mountain hooks for ease in deep snow riding and aggressive cornering.
• PRO-STEER SKIS: PRO-STEER skis feature a reshaped keep and shortened skag for reduced steering effort. Redesigned ribs atop the ski increase stiffness for more precise steering plus bosses added atop the ribs provide traction to prevent slipping when a rider steps on the ski in deep snow.
• WER® NEEDLE SHOCKS: Premium shocks with compression adjusters and remote reservoirs offer the best in tunability and fade-proof performance. Unique needle design uses hydraulic force at the end of the stroke to eliminate harsh bottoming.
• INTEGRATED STORAGE: A weather-tight design seals out the snow and storage can be accessed through zipper and velcro enclosure that is covered by additional material and buckle down straps.
