Vehicle Information
Polaris Charger 372 Snowmobile (1970)
The 1970 Polaris Charger was a high-performance snowmobile, part of the TX Series known for its capabilities. While a specific 'Charger 372' model is not consistently documented in available records for this year, the 1970 Charger was offered with various engine options and trims. The most commonly cited engine was a 398cc two-cylinder, two-stroke engine, producing 27 horsepower at 6,500 RPM, featuring a cooling fan built into the flywheel and equipped with two Mikuni VM30 carburetors. For the 1970 model year, there is no information indicating mid-cycle generation changes. However, Polaris offered a range of engine options and configurations, including the standard Charger, the performance-oriented TX Charger, a factory race sled, and models with 436cc Free Air (F/A) or 340cc Fan Cooled (F/C) engines. These variations allowed for different performance profiles within the same model year. FAQ: How can I ensure parts compatibility for my 1970 Polaris Charger?
