Vehicle Information
Ski-Doo Grand Touring 500 Snowmobile (1996-2003)
The Ski-Doo Grand Touring 500, produced from 1996 to 2003, was a popular snowmobile designed for comfortable two-up touring. Throughout most of its production, it was powered by a reliable 499cc liquid-cooled Rotax twin engine, known for its responsive performance. A notable change occurred in 2002 with the introduction of the Grand Touring 500F alongside the 500 Sport. The "F" designation typically indicates a fan-cooled engine, a significant departure from the liquid-cooled variant, offering a different performance profile. FAQ:
