2021 Polaris® S21EFK8RS

2021 Polaris® 850 PRO RMK 155 3"

Features may include:

• Instantaneous Lift

The combination of the raised and lightweight AXYS chassis, a powerful Polaris engine, and the Polaris-exclusive track designs pop the PRO RMK 155 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.

• Engine Choices for Every Rider

Built to integrate seamlessly with the lightweight and agile Polaris chassis, Polaris 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.

• WER® Shocks

The PRO RMK 155 comes with premium WER® Piggyback Shocks or Monotube Shocks. The WER® Piggyback Shocks with compression adjusters and remote reservoirs offer the best performance across the broadest range of conditions. The WER® Monotube Impact-Extruded Shocks are the lightest weight shock option from Polaris for those riders counting the ounces. The one-piece, simple design is lightweight yet durable. 850 models include exclusive SLS Lightweight Springs.

• Multiple Drive System Options

Multiple drive systems available based upon track length selection.

• 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 AXYS PRO RMK features a compact body panel geometry and design that help give the sled the best lean angle in the industry allowing it to hold even the steepest sidehill lines. The PRO RMK does not "panel out" like other sled brands.

• PRO RMK React Suspension

The PRO RMK React Suspension provides riders with the most precise and effortless ride in the deep snow. Effortlessly initiate sidehills and experience less fatigue with the most predictable ride. It includes a 36"-38" stance, a sway bar designed for predictable handling, and forged a-arms and spindles optimized for strength and durability.

• 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® XT Running Boards - 850 Models

The lightweight PowderTrac® XT Running Boards were developed for extreme riders with new geometry for improved sidehilling and deep snow capabilities. The improved ergonomics maintain usable space for the rider and traction at the rear of the boards.
