Vehicle Information
Ski-Doo TNT 292 Snowmobile (1970-1972)
The Ski-Doo TNT 292, produced from 1970 to 1972, was a popular vintage snowmobile known for its robust and simple design. It featured a consistent Bombardier/Rotax 292cc (or 291.6cc) single-cylinder, air-cooled 2-stroke engine across all model years. For 1972, this engine produced around 20 horsepower. Key variations during this period were primarily related to the suspension systems, offering models with traditional bogie wheels or more advanced slide suspension. For the 1972 model year, “double-action” slides were available as a no-cost option, and the T'NT series, including the 292, received a distinctive “one-year design” cowl with black and white accents. No significant mid-cycle engine changes were noted, with the 292cc displacement remaining consistent throughout the range. Q: Is this product compatible with my 1971 Ski-Doo TNT 292?
A: To ensure perfect compatibility, please use the year and edition selector at the top of the page. Q: What are the main differences between the 1970 and 1972 models?
A: The primary differences involve suspension options and a unique cowl design for 1972. The engine remained consistent.
