Vehicle Information
Ski-Doo Legend 500 Snowmobile (2002-2004)
The Ski-Doo Legend 500, produced from 2002 to 2004, was a popular snowmobile known for its versatility. Initially, the 2002-2003 Legend 500 Sport models featured a 499cc liquid-cooled, twin-cylinder engine, while the 2002-2003 Legend 500F (Fan) used a 496cc fan-cooled engine. A significant change occurred in 2004 for the "500" badged models. The 2004 Legend 500 GT Sport and 500 SS Sport were upgraded with a larger 597cc liquid-cooled, 2-stroke engine, often referred to as the 500SS, effectively moving these models into the 600-class engine displacement. This update aimed to enhance performance and meet evolving rider expectations. FAQ:
