2019 Polaris 850 SKS 155

Seek Something Even Deeper Than Powder

The SKS 155 is the most versatile deep snow crossover sled. Featuring the legendary RMK® Rider Balanced® agility plus bogey wheels and bulkhead cooler to maintain proper engine temperature for mixed-use riding in all snow conditions. Perfect for riders who use trails to get to deep snow. 

Instantaneous Lift

The combination of the raised and lightweight AXYS® chassis, a powerful Polaris®engine, and the Polaris-exclusive track designs pop the SKS on top of the snow. 

AXYS® Chassis
The raised AXYS® chassis increases clearance and reduces drag to keep you on top of the snow. It is purpose-built for mountain riding and allows for improved sidehilling, faster and easier climbing, and instantaneous lift allowing the sled to pop onto the snow faster. The aluminum over structure is lightweight and durable for all types of riding. Taller spindles increase clearance to reduce drag. 

Liberty® Engine Choices for Every Rider
Built to integrate seamlessly with the lightweight and agile Polaris® chassis, Liberty® engines feature class-leading power-to-weight ratios and set a new benchmark for ultimate performance with our complete line-up of powerful options. 

Rear Suspension
The lightweight, rigid rear suspension design features revised geometry to control pitch. This improves weight transfer, delivering better control and a more compliant ride. The rigid suspension delivers power directly to the snow. Off-trail, riders will notice improved weight transfer while maintaining the approach angle. On-trail, riders will notice a more compliant and comfortable ride. The rear suspension features a rail design that helps lift the rear skid while driving it forward. 

Walker Evans® Shocks
The Walker Evans® Impact-Extruded Monotube Shocks offer the best performance across the broadest range of conditions. 

Rider Balanced® Control

The AXYS® platform features Rider Balanced® positioning that delivers ultimate control for the rider for precise, effortless sidehilling. 

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 and can occur on steep inclines and while carving.

Narrow, Adjustable Front End
Narrow 39" - 41" adjustable front end is ideal for setting up for more stability or ultimate performance while tree-riding or boondocking. 

Forged, Aluminum A-Arms
The efficient one-piece design reduces weight and improves optimal strength, suspension performance, and sled handling. The design reduces unsprung mass, resulting in improved ride quality and increased maneuverability. 

Immediate Response

The world's best mountain sled is built to be the lightest and most rigid, making it incredibly responsive to rider inputs. This allows you to change direction and maneuver confidently in all conditions. 

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. 

Lightweight
Polaris® snowmobiles are the lightest sleds on the mountain. They have always been light and rigid with added strength and durability while reducing weight on the RMK® AXYS® platform. Providing riders with instantaneous lift, Polaris sleds help riders get up on top of the snow faster. 

Additional Features

AXYS® Performance Seat
The AXYS® Performance Seat provides the ideal mix of comfort and support for seated riders, and its design provides standing riders with the greatest room to move. 

LED Lights
All models built on the AXYS® platform feature standard LED headlights to deliver the industry's best lighting that is 80% brighter than incandescent lighting. 

MessageCenter Gauge
Informative and easy to read, this gauge keeps a rider aware of sled operating conditions and provides a wealth of additional data. 

Polaris® Interactive Digital Display
This exclusive and industry-leading full color display provides important information and capabilities to the rider such as: sled performance, Bluetooth™, GPS mapping, Clock, and LH Control. This gauge comes as an option on some models and is also available as an accessory. 

Integrated Storage Options
Optional accessory storage was designed and developed right along with the AXYS® platform so it installs securely and features seamless, integrated styling that matches the sled's design lines. Engineered with the highest quality of materials.
