I had a more severe issue when I owned my Ducati ST4. It was far worse. Fortunately I bought some convertibars and they were wonderful. The only issue were the bars were narrower. It was the only way I could get them to work with the fairing. So much narrower that I nearly dropped the bike a couple times due to the lack of leverage. However once I got used to it I realized that a narrower arm position was better, less aerodynamic drag. That said, if the cables give me any problem at all due to not being long enough I will either replace the bars or cut an inch off each end of the factory bars. That will give me some slack and might give me less drag as well.
Here's a pic of the Convertibars. They're narrower and obviously taller and also swept back a bit.
