If you added 'to be' on to the title of this thread then Halle Berry's bikini from Die Another Day. Otherwise, yup James Bond's DB5 Coupe.
Some good runners from Triumph...including Brando's "Wld One" model. https://en.wikipedia.org/wiki/Triumph_Thunderbird#/media/File:Triumph_6T_650_cc_Thunderbird_1950.jpg
I can't remember all of the details, but I read a critique of the bike on a website a bit back, and it was clipped together for the film, and would be virtually unridable in reality due to the cabling and some other aspects.
