With all of the press Buell is getting these days, their PR department must be working till the wee hours of the morning or maybe the producers just thought a Buell was the best choice. Either way, according to this leaked call sheet for the upcoming Transformers 2 movie, there is a Buell Firebolt that transforms into a female robot among the various multi hinged vehicles ready to do battle with the decepticons. Hmm, ... doesn't look like a factory color.
UPDATE: The first comment below by Clive points out the Buell part is speculation not actually specified, only a motorcycle is called for. Guess we'll have to see the movie.
