Moto Guzzi is an Italian motorcycle manufacturer. It is one of seven brands owned by Piaggio. Established in 1921 in Mandello del Lario, Italy, the company is noted for its central historic role in Italy's motorcycling manufacture, its prominence worldwide in motorcycle racing, and a series of industry innovations – including the first motorcycle centre stand. Carlo Guzzi's first engine design was a horizontal single that dominated the first 45 years of the company's history in various configurations. Through 1934, each engine bore the signature of the mechanic who built it. As originally envisioned, the company used racing to promote the brand. On 30 December 2004, Piaggio & Co. S.p.A acquired Aprilia and thereby Moto Guzzi, forming Europe's largest motorycle manufacturer. Moto Guzzi S.p. A officially becomes a Unico Azionista of Piaggio, part of Immsi S.p.A. Investments have allowed introduction of a series of competitive new models in rapid succession. In November 2007, Moto Guzzi unveiled the retro-themed 2008 V7 Classic at the Motorcycle and Bicycle Manufacturers show in Milan, Italy.
