This is Yamaha’s casting technology MT-09 SKELETON MODEL We have accumulated our knowledge of casting since before our foundation. Our high quality and uniqueness are also highly evaluated outside, and we are expanding our field sales business as well. This time, Revs Now focuses on the strong points of our casting.

  • The great cast component world - a crystal of technology and beauty
  • Analyzing the strong points of Yamaha’s casting
  • Supporting and securing Yamaha quality
  • Teamwork and challenging spirit at heart
  • Formidable casting sector told by the  “YZF-R1” developer
  • Our history is the history of casting

    We have taken over the casting technology cultivated with piano frames of Nippon Gakki Co., Ltd. (the current Yamaha Corporation) and the trial and mass production of the first motorcycle “YA-1” released in 1955 and consistently maintained our independent development and in-house production system of casting. Since then, we have continuously strived to develop our technologies, extending our fields further to motorcycle engines and bodies, automobile engine parts, and marine engine parts.
  • At once product and art

    Casting is a technology where metals such as aluminum and magnesium are heated and melted at a high temperature (molten metals) and are poured into molds and solidified by cooling down to make metal products. It allows free molding and monolithic molding and was used for the molding of statues of Buddha and coins in old times. Among many metal working technologies, it is a manufacturing technology that is also well suited for artistic products such as gate doors and exterior parts of motorcycles for which appearance is important.
  • Casting is a “living matter”

    Aluminum alloy melts at approx. 700oC. The casting conditions such as the climate condition of the day, quality of the metal ingot used as the material, temperature of the melted metal (molten metal), and the status of the mold into which high-temperature molten metal is poured vary every second. This is why casting is called “living matter.”
    It is our accumulated know-how and knowledge of people involved that ensure stable quality under varying conditions. Casting full of know-how is often likened to agriculture and winemaking, and we are working hard together to produce good products by controlling conditions.
