context_page_description: Tehuelche was an Argentine motorcycle that was presented to the public in March 1957, and produced until 1964.
  Other attempts were made, mostly unsuccessful, to produce an Argentine motorcycle; however, the Tehuelche was the only motorcycle that was mass-produced continuously in its seven years of manufacturing in Argentina. It competed at a local level with other motorcycles, which were produced under license from European models and companies: the Puma Primera and Puma Segunda, the Zanella, and the Gilera, among others. The Tehuelche distinguished itself not only by the characteristic sound of the gear train, but also for its performance in its racing career.
