RMK

Polaris introduced this mountain-snowmobile nameplate for the 1998 model year, when the Rocky Mountain King 700 arrived as the brand’s first purpose-built mountain sled. Early coverage from Polaris describes the 1998 machine as the start of the line’s deep-snow identity, with a long track and mountain-specific suspension designed for steep terrain and soft snow. Over time, the badge became shorthand for Polaris mountain performance rather than a single model variant, and it evolved through successive chassis eras and engine updates while staying focused on backcountry riding. Polaris has continued to expand the family in modern form, including current high-performance off-trail variants such as PRO RMK and RMK Khaos, which carry the same mountain-riding mission forward. The nameplate remains an active part of Polaris’ snowmobile lineup today.
