  • LIGHTWEIGHT: The 800 SKS 146 is lightweight AND rigid, so rider inputs and power are transferred with maximum efficiency, and the sled is easy to maneuver in deep snow and accelerates fast on the trails. Design optimization software results in lean, strong construction of the chassis. The weight of every component & sub-system is minimized without compromising strength or performance. At 456 lb. the 800 SKS 146 on the AXYS platform is lightweight & strong.

Instantaneous Lift

  • RIDER-BALANCED AXYS® CHASSIS: The AXYS® chassis for the SKS 146 provides rider balanced characteristics for the crossover rider. This sled offers both instantaneous lift when off-trail in the deep snow, as well as smooth handling and cornering when on-trail. The rider is placed 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. Purpose-built for crossover riding. Provides improved sidehilling & faster, easier climbing. Upon acceleration, sled gets instantaneous lift & stays on top of the snow. Aluminum overstructure is lightweight & durable for all types of riding
  • IGX 146 REAR SUSPENSION: The IGX – Ideal Geometry Xover – Rear Suspension delivers a smooth ride and outstanding handling on all terrain and in all snow depths and conditions. IGX Rear Suspension features optimized geometry to control pitch. Minimal bottoming & drag off-trail. Rail beam is tipped for optimal performance.
  • PROVEN 800 CLEANFIRE® H.O. ENGINE: Developed in conjunction with the AXYS platform, the proven 800 Cleanfire® H.O. Engine delivers +10% increase in power-to-weight ratio and quicker throttle response to generate instantaneous lift. The integrated mounting position optimizes the balance of the chassis. Featuring: Grooved piston for improved durability and engine life 3-stage electronically-controlled exhaust valves for increased power and responsiveness Electronic oil pump for reduced throttle effort and improved durability Thermostat with bypass warms up to operating temperature 40% faster and improves durability High-efficiency intake and exhaust for improved breathability, which increases power Exclusive VForce Reeds for more power and improved reed life Lightweight crankshaft that's more durable, 2.5 lbs lighter and has 25% less inertia This is the same 800 H.O. engine released with great success in the 2015 Polaris RUSH and Switchback models, and has been proven through 100,000+ field testing miles.
  • 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: New porous intake duct material and high-flow exhaust system create a better breathing engine package for more power. An all-new silencer provides reduced sound levels. Vforce reeds provide improved performance, throttle response and reed durability.
  • VFORCE REEDS: Provide improved performance, throttle response, and reed durability.
  • LIGHTWEIGHT CRANKSHAFT: 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 since the 2013-14 and 2014-15 season, showing it's proven durability.
  • 800 H.O. GROOVED PISTON: New grooved piston was designed specifically for the new 800 HO Cleanfire® Engine to increase durability and engine life.
  • 2.25" PEAK TRACK: 2.25” deep lugs feature a variety of designs & are positioned for optimized traction. Peak track delivers outstanding traction in deep powder & in low-snow conditions or on-trail. Spacing & positioning of lugs produces the most effective traction in all snow conditions. Rigid lug support columns enhance traction in soft & hard-pack snow. Stiff outer lug bars provide better lateral control for improved handling.
  • WALKER EVANS® PIGGYBACK CLICKER SHOCKS: The Walker Evans® Piggyback Clicker Shocks with compression adjusters and remote reservoirs offers the best performance across the broadest range of conditions.

Rider Balanced Control

  • AXYS® BODY PANEL DESIGN: The compact AXYS body design provides the industry’s highest lean angle to keep the weight on the skis and track – even in the meadows – and it minimizes paneling out. Paneling out compromises control & can occur on steep inclines & while carving. AXYS narrow ergonomic design avoid paneling out. AXYS bodywork fuels rider confidence, provides a larger “sweet spot” for meadow riding. With weight on skis & track, rider input is optimized & rider feels the greatest control of the sled
  • NARROW, ADJUSTABLE FRONT END: The SKS features the same narrow 39"-41" adjustable front end as the PRO-RMK, ideal for setting up for more stability or ultimate performance while tree-riding and boondocking.

Rider Centric Comfort
