Moto-Ski Super Sonic 340 Snowmobile (1979-1981)

The Moto-Ski Super Sonic 340, produced from 1979 to 1981, was a high-performance snowmobile that shared many characteristics with its Ski-Doo counterpart, the Blizzard 7500. This model was consistently powered by a liquid-cooled, twin-cylinder Rotax Type 354 engine, with a displacement of 340cc (sometimes referred to as 339cc). While specific horsepower figures for the Super Sonic 340 are not always explicit, its close relation, the 1979 Ski-Doo 7500 Blizzard with a 340cc Rotax engine, was rated at approximately 70 horsepower, highlighting its powerful nature. Between 1979 and 1981, there were no significant mid-cycle generation or engine changes for the Moto-Ski Super Sonic 340. The model maintained its core liquid-cooled Rotax Type 354 engine throughout this period. Various trim designations appeared, such as "Super Sonic 340 L/C" and "Super Sonic Cross Country" in 1979, "Super Sonic LC" and "7500" in 1980, and simply "Super Sonic" in 1981. These were primarily naming variations reflecting its close ties to Ski-Doo models after Bombardier's acquisition of Moto-Ski.
