Vehicle Information
Ski-Doo Legend 600 Snowmobile (2002-2004)
The Ski-Doo Legend 600, produced from 2002 to 2004, is a touring snowmobile known for its reliability and comfort. Initially equipped with a 597cc carbureted Rotax twin engine, it offered ample power and great durability. In 2004, a significant evolution occurred with the introduction of the 594.4cc Rotax 600 H.O. SDI (High Output, Semi-Direct Injection) engine. This new powertrain, slightly smaller in displacement, delivered increased performance (approximately 110-115 horsepower) and improved fuel efficiency thanks to its semi-direct injection technology. Various trims were available over the years, such as the SE, GS, and Sport models, offering different equipment options to meet riders' needs.
