Yamaha Motor Company Limite (ヤマハ発動機株式会社, Yamaha Hatsudōki Kabushiki-gaisha?) (TYO: 7272), a Japanese motorized vehicle-producing company (whose HQ is at 2500 Shingai, Iwata, Shizuoka), is part of the Yamaha Corporation. After expanding Yamaha Corporation into the world's biggest piano maker, then Yamaha CEO Genichi Kawakami took Yamaha into the field of motorized vehicles on July 1, 1955. The company's intensive research into metal alloys for use in acoustic pianos had given Yamaha wide knowledge of the making of lightweight, yet sturdy and reliable metal constructions. This knowledge was easily applied to the making of metal frames and motor parts for motorcycles. Yamaha Motor is the world's second largest producer of motorcycles. It also produces many other motorized vehicles such as all-terrain vehicles, boats, snowmobiles, outboard motors, and personal watercraft.
