Features May Include:

AXYS Platform

• The raised AXYS platform increase 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.

Patriot Engine

• Designed for class-leading durability, responsiveness, unrivaled acceleration and industry's best power-to-weight. The most powerful snowmobile engine ever built by Polaris.

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 163 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.

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.

PowderTrac® XT Running Boards

• 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.

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.

New SnowCheck Exclusive QuickDrive2 (QD2)

• Introducing the all-new, SnowCheck Exclusive, low-inertia QuickDrive2 (QD2). QuickDrive is the lightest drive system in the industry and produces the lowest inertia for maximum flickability. QD2 boasts a 10% gear reduction for even quicker response and track speed. The system has been optimized for both 2.75” and 3” track lug heights.

PRO-Lite Seat

• Mountain snowmobiling requires a different seat design and that is what Polaris delivers. The PRO-Lite seat is shorter to allow you to easily swing a leg over from one side of the snowmobile to the other.

LED Lights
