The 1972 Ski-Doo® Blizzard 640 was built for speed. Designers used cutting edge technology of the time, powering the snowmobile with a 3-cylinder 645 cc Rotax® engine. The Ski-Doo® Blizzard 640 made snowmobile racing history in 1972, when Yvon Duhamel won the gruelling 500-mile cross-country event from Winnipeg to St. Paul, Minnesota.
