The Factory Yamaha MotoGP team, which used a plain carbon-black livery with white logos on day one of the Sepang MotoGP test, will appear in 'Racing Blue' colours on days two and three.

The de-branded design is to be filmed for a Yamaha corporate video as part of the ongoing Yamaha World GP 50th Anniversary activities. The design will only be used for the last two days of the Sepang test.

Yamaha, which is yet to announce a new title sponsor, will unveil the 2011 race livery of world champion Jorge Lorenzo and new team-mate Ben Spies at the second Sepang test, later this month.
