Vehicle Information
Arctic Cat Cheetah 500 Snowmobile (1976-1990)
The Arctic Cat Cheetah 500, a versatile snowmobile, was produced from 1976 to 1990. It was known for its 500cc class engines, primarily fan-cooled Suzuki twins, with a brief appearance of a 529cc option in later years. The model saw several trims, including the early Cheetah 5000, and later the Cheetah F/C, Cheetah UC, and Cheetah Touring. The production of the Cheetah 500 experienced a significant interruption between 1982 and 1984 due to the bankruptcy of Arctic Enterprises. Production resumed for the 1985 model year under a new company. This period marked a clear generation break. Further updates included a notable redesign in 1986, introducing a "new Cheetah," and the implementation of the AFS (Arctic Front Suspension) system in 1987, enhancing handling and ride comfort. The 529cc engine option became available for certain trims in 1987 and 1988. FAQ:
