I don't know how you can measure these things objectively (I'll leave that to the motorcycle press), so I won't say that the new 2011 Triumph Speed Triple handles better than the Superduke.
But I will say that I like the way my new 2011Speed Triple handles better than the way my 2007 Superduke handles. At least for me the new Triumph noticeably outhandles the KTM.
