I actually asked about that very question seeing how I have a 07 Bulldog.
Yes and no......
Someone from BDM told me,
The new Bulldog has a different triple tree set up with drilled and tapped holes to mount the fairing frame to. However you could put a 2009 Bulldog front end on a 2007 and it should work. Probably have to change the handle bars though since the sweep of the bars are different for fairing clearance.
If you have access to a very good machine shop you might be able to adapt your stock triple trees to take the fairing frame. That might be better than a front end swap. You might still have to change the bars though for fairing clearance.
