Yamaha Motor Corporation

Yamaha Motor Corporation is a company of automobile engineering subsidiary of Yamaha which developed engines of competition intended for the Formule 1. From 1982 to 1997, the company was directed by John Judd, which had already its own dispensary of design of engines (Judd). In fact, as from the moment when Yamaha decided to be invested under its proper name in F1, the engines designed by Judd either were baptized Judd, or Yamaha badges.
