2011 Polaris PRO RMK 163 800cc - The 2011 PRO‑RMK 800 163 is a mountain / deep‑snow snowmobile, built primarily for back‑country, powder, steep terrain, and off‑trail snow. - It belongs to the “PRO‑RMK / PRO‑RIDE” line by Polaris, designed to prioritize light weight, snow‑floating/traction, maneuverability and power, rather than on‑trail cruising comfort or touring amenities. Features May Include: - Deep snow, powder, mountain terrain, back‑country riding: The 163″ track, modest weight, and snow‑specific chassis geometry give excellent flotation — helpful for deep powder, side‑hills, glades, untracked slopes or tree runs. - Agile but capable despite long track: The PRO‑RIDE chassis with its lighter structure and over‑engine configuration (lower center of gravity) gives the 2011 PRO‑RMK a balance between the flotation of a long‑track sled and relatively nimble handling for technical terrain. - Good power-to-weight ratio for mountain climbs & powder bursts: The 800 cc 2‑stroke fuel‑injected engine delivers solid torque and power for climbs, deep‑snow acceleration, and performance when you need punch. - Adjustability and rider‑oriented design: Adjustable ski stance, capable suspension, and lightweight construction give flexibility depending on terrain and snow conditions; the design favors rider‑mobility and control in deep‑snow and variable terrain. - Reasonable fuel capacity for back‑country trips: 11.5‑gallon tank offers a decent range, useful when riding remote areas or long powder runs.
