Polaris TX Starfire 439 Snowmobile (1972-1973)

The Polaris TX Starfire 439, produced for the 1972 and 1973 model years, was a high-performance racing snowmobile. Known for its race-oriented design, it featured a 439cc (often referred to as 440cc) triple-cylinder, free-air Starflame Fuji engine. This model was at the forefront of Polaris's racing efforts during its era. Significant changes occurred between these two model years. The 1972 models were known as "TX factory racers" and typically featured cast iron bores. For 1973, the "TX Starfire" name was formally adopted for production models, designed for both cross-country and oval racing. The 1973 Starfire introduced "Big fin" engines for improved cooling, all equipped with CDI systems, a notable upgrade from the 1972's cast iron bores. Furthermore, the 1973 model boasted an all-aluminum welded chassis for lighter weight, a lightweight Equaliberator slide-rail suspension, hydraulic disc brakes, and the introduction of a jackshaft.
