Vehicle Information
Polaris TX 440 Snowmobile (1973-1980)
The Polaris TX 440, a prominent snowmobile model from 1973 to 1980, was renowned for its performance and racing heritage. Throughout these years, it consistently featured a 432cc to 440cc twin-cylinder, free-air cooled engine, often identified as the Polaris SuperStar or Fuji EC44PT-05. While the core engine remained largely consistent, Polaris continuously refined the chassis and suspension, integrating advancements from its racing division. Notable variations included the 1973 TX Starfire 440, which offered a 439cc triple-cylinder option and an all-aluminum welded chassis. A significant evolution occurred in 1976 with a 'radically redesigned chassis' featuring an aluminum slide rail suspension system, enhancing handling and stability. Further refinements in 1977 introduced monoleaf ski springs and extruded aluminum slide rail suspension, with the 1978 model built on the 'legendary Starfire chassis'. These continuous updates ensured the TX 440 remained a competitive and high-performing sled throughout its production run. FAQ:
