Vehicle Information
Polaris XC 700 Snowmobile (2004-2005)
The Polaris XC 700, a powerful and reliable snowmobile, was offered for the 2004 and 2005 model years. It was powered by a 700cc (or 701cc) liquid-cooled, horizontal in-line, two-stroke engine, featuring the Variable Exhaust System (VES) and Detonation Elimination Technology (DET). This robust Liberty engine was paired with the agile "EDGE" chassis, ensuring a dynamic riding experience. For 2004, the primary model was the XC SP 700, often referred to as the Indy 700 XC SP, and was largely a carryover model. In 2005, the XC SP 700 continued as a core offering. A notable update for 2005 was the inclusion of the Polaris Adjustable Seat System (PASS) as standard equipment. Additionally, mountain-specific trims like the 700 RMK 144" and 700 RMK 151", as well as an M-10 suspension option (700/800 XC SP M-10 F/O), were introduced, expanding the range's versatility. FAQ:
