In 1926, three brothers, Adriano, Marcello and Bruno Ducati, founded Societa Scientifica Radio Brevetti Ducati in Bologna producing various radio components. In December 2005 Ducati returned to Italian ownership after Investindustrial Holdings purchased most (Texas Pacific kept one share) of the shares. Investindustrial is the investment fund of Carlo and Andrea Bonomi. Ducati has a long and successful history in racing, not least with British rider Carl Fogarty winning four Superbike World Championships, between 1994 and 1999, on a Ducati 916. In 2011, Ducati will be rode by Italian racing superstar Valentino Rossi in the MotoGP season.
