800 SKS 146

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

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

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

• 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.

Forged Aluminum A-Arms

• Efficient 1-piece design reduces weight & improves optimal strength
• Improves suspension performance & sled handling
• An innovative industry-first from Polaris
• Design reduces unsprung mass, resulting in improved ride quality & increased maneuverability
