Vehicle Information
Polaris Gemini Snowmobile (1979-1981)
The Polaris Gemini snowmobile, produced from 1979 to 1981, was designed as a reliable and accessible option for families and new riders. Initially available with a 244cc single-cylinder fan-cooled engine (EC25PS), also known as the Gemini 250, it was praised for its simplicity. For the 1980 model year, Polaris expanded the lineup by offering two engine choices: the familiar 244cc single-cylinder (EC25PS) and a new 244cc twin-cylinder fan-cooled engine (EC25PM-01). However, a notable change occurred for 1981. Polaris streamlined its offerings, discontinuing the twin-cylinder option. From 1981 onwards, the Gemini was exclusively equipped with the 244cc single-cylinder engine, with a version featuring a rubber track also available. This final iteration was positioned as a low-price, fuel-efficient model. This shift reflected Polaris's strategy to standardize engine use across its snowmobile range. FAQ:
