Vehicle Information
Ski-Doo TNT 440 Snowmobile (1971-1978)
The Ski-Doo TNT 440, produced from 1971 to 1978, was a popular snowmobile known for its performance and versatility. Primarily powered by Rotax twin-cylinder engines ranging from 435cc to 440cc, this series offered various configurations to meet the needs of snowmobilers. Over the years, the TNT 440 underwent significant evolutions. Early models offered a choice between traditional bogie wheel suspensions and the newer slide rail suspensions. In 1974, the introduction of the TNT Everest marked a turning point with a long-track version and revamped slide-rail suspension for improved flotation and stability. The year 1975 saw the arrival of the TNT Everest 440E, a premium model featuring electric start and CD ignition. Towards the end of its production, from 1977 to 1978, the model gradually transitioned from free-air cooled engines to fan-cooled engines, offering adapted cooling options. FAQ:
