Vehicle Information
Polaris TX-C 440 Snowmobile (1981-1982)
The Polaris TX-C 440, offered in 1981 and 1982, was a notable snowmobile, representing a significant step for Polaris with its new engine and oil injection system. This performance-oriented, fan-cooled model was powered by a 432cc (or 436cc in some references) oil-injected, fan-cooled, two-cylinder engine, producing mid-50s horsepower. It was equipped with matched Mikuni 34mm slide-valve carburetors. The TX-C 440 was a distinct model, without multiple sub-trims. Introduced in 1981, it featured a new 432cc engine placed in the 1980 TX-C 340 chassis, making it one of the first Polaris models to incorporate oil injection. The 1982 model continued with the same engine and overall design, utilizing the Fuji EC44-2PM-1100 432cc engine. There were no significant mid-cycle generation or engine changes between 1981 and 1982; the 1982 model was a continuation and the final evolution of the iconic leaf-spring TX lineup. FAQ:
