Vehicle Information
Moto-Ski Ultra Sonic 440 Snowmobile (1980-1983)
The Moto-Ski Ultra Sonic 440, produced from 1980 to 1983, was a high-performance snowmobile known for its powerful liquid-cooled engine and aggressive styling. It was considered Moto-Ski's top-of-the-line performance model during this period, often drawing comparisons to the Ski-Doo Blizzard 9500. Across the 1980 to 1983 model years, the Ultra Sonic 440 consistently featured a liquid-cooled, rotary valve twin-cylinder Rotax engine. Its displacement was most commonly cited as 440cc, though some sources mention 437cc or a Rotax Type 454, these variations likely referring to the same engine. The 1982 model, for instance, delivered an estimated 82 horsepower, a consistent performance that rivaled its Ski-Doo Blizzard 9500 counterpart. There is no indication of significant mid-cycle generation or engine changes for the Ultra Sonic 440 between 1980 and 1983. The model was offered as a singular, high-performance offering, without distinct trim levels. Q: How can I ensure this part fits my Moto-Ski Ultra Sonic 440?
