The 800 Switchback® Assault snowmobile is for aggressive, backcountry riders that demand off-trail agility and on-trail confidence. Its powerful, proven 800 H.O. Cleanfire® engine paired with the AXYS® Chassis and IGX 144 Rear Suspension deliver Rider-Balanced™ Control, Unrivaled Acceleration, and Rider Centric Comfort.
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.
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.
The PowderTrac Hybrid running boards offer optimized design with 56% open space for maximum snow clean out while maintaining extreme strength.
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 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.
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.
The AXYS Performance seat utilizes a high-performance seat foam, and the seat design is narrower in front to provide greater maneuverability.
Informative and easy to read, this instrumentation keeps a rider aware of sled operating conditions and provides a wealth of additional data.
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 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.
