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 144 Rear Suspension
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.
At 456 lbs, the Switchback ASSAULT on the AXYS 144 platform is the industry-leading lightweight 50/50 crossover snowmobile. It allows you to get up on top of deep snow faster and offers quick acceleration.
800 Cleanfire® H.O. Engine
Developed in conjunction with the AXYS platform, the proven 800 Cleanfire® H.O. Engine delivers class-leading acceleration. The integrated mounting position optimizes the balance of the chassis. Featuring:
3-Stage Electronically-Controlled Exhaust Valves
3-stage electronically-controlled exhaust valves provide improved running quality, crisper throttle response, smoother idle and improved fuel economy. The active feedback for the exhaust valve position provides more accurate fueling in transient situations. These exhaust valves also improve combustion stability, leading to improved durability and engine life.
Electronic Oil Pump
Electronic oil pump eliminates power-robbing gear drive – and provides more precise, improved oil delivery for performance and durability as well as a 35% reduction in throttle effort. Requires no adjustments.
High-Efficiency Intake and Exhaust
Porous intake duct material and high-flow exhaust system create a better breathing engine package for more power. The silencer provides reduced sound levels while on the trail. Vforce reeds provide improved performance, throttle response and reed durability.
Provide improved performance, throttle response, and reed durability.
Lightweight crankshaft weighs 2.5 lbs less, delivering 25% lower inertia and quicker throttle response and spooling. This provides improved acceleration. Designed and engineered specifically for the 800 Cleanfire® H.O. Engine for increased durability, this same lightweight crankshaft is used in Polaris Race sleds, including during the past 2013-14 and 2014-15 seasons, showing it's proven durability.
800 Cleanfire® H.O. Engine Piston
Grooved piston was designed specifically for the 800 HO Cleanfire® Engine to increase durability and engine life.

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.
Polaris MessageCenter Gauge
Informative and easy to read, this instrumentation keeps a rider aware of sled operating conditions and provides a wealth of additional data.
Interactive Digital Display
Another industry first for Polaris - the most advanced instrumentation in snowmobiling. This 4.3"" high resolution, full color, LCD digital display provides a rider with information including:
The hood and windshield designs produce significantly enhanced wind protection for a rider, and the foil on the side panels further enhances protection.
Premium Fit & Finish
Interfacing surfaces between body panels and components are shorter for minimized gaps
Choice of Cobra 1.35” or Series 4 2.0” Track
The 800 Switchback Assault comes with the Cobra 1.35” Track with softer lugs that feature traction teeth for better grip on hard-pack surfaces and also delivers great performance on soft, loose snow off-trail. Also available: Customers can select an 800 Switchback Assault model with electric start and the Series 4 2.0” track that feature a stiff lug base for hard-pack performance with soft and flexible tips for deep snow traction.
Walker Evans 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.
New ProTaper Handlebars are aluminum and feature a flat design with integrated mountain hooks for ease in deep snow riding and aggressive cornering
The PRO-STEER ski features a reshaped keel and shortened skag for reduced steering effort. Redesigned ribs atop the ski increase torsional 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.
