I am assuming you mean in second gear? Its because the engine has been moved forward slightly on the 06-07 models. This was done to help keep the front wheel down in racing.
It will come up it just requires a little more effort in second. When i first bought my 06 I was saying the same thing but I went out and practiced. Believe me I am no professional, I still have a lot to learn and am not consistant, but it will come up.
Here is a vid of some guy clutching up a second gear seater on the 750 although the original poster claimed it was him on a 600 until he was owned.
