Vehicle Information
Polaris TX Charger 398 Snowmobile (1970-1971)
The Polaris TX Charger 398, produced from 1970 to 1971, was a prominent snowmobile within the acclaimed TX series, renowned for its performance and racing heritage since its introduction in 1968. This model was powered by a robust 398cc, 2-cylinder, 2-stroke engine, delivering 27 horsepower at 6,500 RPM in 1970, with consistent specifications for 1971. The "398" designation refers to the engine displacement, while "Charger" was a key trim level. Between 1970 and 1971, the Polaris TX Charger 398 did not undergo significant mid-cycle generation changes. The core design and the 398cc engine remained consistent. However, the broader TX Charger lineup saw an expansion of available engine options in 1971, including displacements like 294cc, 335cc, 432cc, 488cc, and 795cc, offering consumers more choices within the series. This represented an evolution in powerplants rather than a fundamental change to the 398cc model itself. FAQ:
