I had a gsxr 6 before my 916/996 and have to say the duke is so stable it's like its on rails.
I run showa front forks with ohlins on the rear I have gone one click softer than standard on the front, and one off on the compresion on the rear.
Rear tyre is down sized to a 180 to get rid of the understeer.
You do have to put a bit more effort into the bars but the results are well worth it
