1971 was the first year for the production of the EXT. Every other factory had been out to beat the highly successful Arctic Cats in 1970, so the racing department in Thief River Falls, MN came up with the built for racing EXT models. These sleds were based on the newly introduced Puma short chassis and were powered by Kawasaki free air engines. The EXTs powered by the new Kawasaki engines proved to be a winning combination for Arctic Cat.
The 1971 factory EXT race team members were Roger Janssen, Fred Jillson, Larry Colton, Paul Eggebraaten, Dave Thompson, Charlie Lofton & Dennis Bakke.
