Yamaha has confirmed that it will join Honda for a private MotoGP test session at the new Austin circuit from March 12-14.
The Texan track, one of three US rounds alongside Laguna Seca and Indianapolis, will host round two of the 2013 world championship from April 19-21.
Austin held its inaugural F1 event, to widespread praise, at the end of last season.
Ducati has not yet announced if it will also make the (costly) journey to America.
The three official pre-season tests are to take place at Sepang (February 4-6), Sepang II (February 26-28) and Jerez (March 23-25).
