Vehicle Information
Polaris RMK 700 Snowmobile (2004-2010)
The Polaris RMK 700, a high-performance snowmobile designed for mountain riding, was produced from 2004 to 2010. Throughout these years, it primarily featured a 700cc liquid-cooled, 2-stroke engine, though specific configurations varied. It was known for its agility and power in challenging terrain. Significant updates occurred during its production run. In 2004, the RMK 700 adopted the EDGE chassis, alongside updates to its chaincase and braking system. A notable engine change happened in 2006, briefly increasing displacement to 755cc, before returning to a 700cc HO Cleanfire Injection engine in 2007, which also marked the introduction of the "Dragon" trim with substantial weight reduction and suspension upgrades.
