Vehicle Information
Ski-Doo Legend 1000 Snowmobile (2003-2005)
The Ski-Doo Legend 1000, produced from 2003 to 2005, was a touring snowmobile model that introduced the 989.6cc (often rounded to 1000cc) V-Twin 4-stroke engine to the Ski-Doo lineup. This liquid-cooled, fuel-injected engine offered a powerful 4-stroke option. These models also benefited from the revolutionary REV platform, launched in 2003, which redefined rider positioning for improved ergonomics and control. Various versions were available, such as the Sport, SE, and GT SE trims, offering different configurations to meet riders' needs. Q: Is this product compatible with my Ski-Doo Legend 1000?
