Vehicle Information
Ski-Doo TNT 775 Snowmobile (1971-1972)
The Ski-Doo TNT 775, produced from 1971 to 1972, was a high-performance snowmobile renowned for its powerful Rotax twin-cylinder engine and racing-oriented design. For its era, it was considered an exceptionally fast machine. During its short production run, the TNT 775 saw notable developments. The 1971 model featured a 771 cc engine with dual HD carburetors and was available with either bogie wheel or slide suspension (TNT 775S). In 1972, the TNT 775 received a slightly larger 775 cc engine, often equipped with massive dual Tilson carburetors. More significantly, the 1972 model adopted a wider, more robust chassis designed for an 18-inch track, enhancing stability, particularly for racing. Buyers in 1972 could also choose between bogie wheel and slide rail suspension systems. These changes reflect a rapid evolution in snowmobile technology during this period. FAQ:
