Description

Yamaha Motor’s core areas of expertise include powertrain technology originating from motorcycle development, and the chassis/hull technology that complements the performance of our vehicles and boats. Further to this, Yamaha Motor expanded into developing electronic control technology and component technology in order to build a multi-axial business structure while at the same time pursuing globalization of our corporate activities. Our powertrain technology is now implemented in new fields such as marine engines, recreational vehicles, and other power products, while our FRP processing expertise (part of our core competence in hull technology) is now used for pool manufacturing and personal vehicle exteriors.
