Releasing its 2011 World Superbike livery today, Yamaha had to unveil its YZF-R1 with a profusion of the color blue, and total lack of a title sponsorship. Not renewing its contract after the 2010 season, Italian milk producer Sterilgarda is notably absent from the team livery. It might have been assumed that Sterilgarda would stay on to sponsor Italian rider Marco Melandri, but the once promising MotoGP rider obviously did not have the drawing power for the Italian brand.

This lack of corporate sponsorship is a worrying trend for the Japanese motorcycle manufacturer, as Yamaha has yet to announce a sponsor for its MotoGP team, after Fiat exited with its bags of money when Valentino Rossi left Yamaha for Ducati Corse (there’s considerable talk that when Yamaha debuts its MotoGP livery in Sepang later this month, it’ll be with corporate colors as well).
