Is this the 2012 KTM 690 Duke? MCN reports that an Austrian KTM enthusiast spotted the new Duke at a gas station near Mattighofen. It seems that the bike on the picture is an early prototype of the 2012 690 Duke, which will gain a couple of extra horses up on its predecessor. The 2012 Duke will most likely feature new headlights and two-part muffler design, but it’s also possible that this is a brand new, 450-500cc Duke. Time will tell.
