Vehicle Information
Moto-Ski MS-18 399 Snowmobile (1971-1972)
The Moto-Ski MS-18 399, produced from 1971 to 1972, was a popular snowmobile known for its robust 398cc JLO (LR399) engine, delivering 28 horsepower. This model was a key offering in Moto-Ski's lineup during these years. While the core 398cc JLO engine remained consistent for the MS-18 399 across both years, the broader MS-18 model saw general updates. In 1971, it gained engine shrouding and transitioned to a single-sprocket track. For 1972, changes included a shift from fiberglass to plastic cowlings, a revised cowling design, and an all-black seat. These updates, alongside Bombardier's acquisition of Moto-Ski in late 1971, marked a period of evolution for the brand. FAQ:
