Hey I am new here but I've been riding for 29 years now, so a little bit of thought has gone in to your question.
Here's a short list of bikes that I would think about.
M109R (looking to put one in my garage too!)
Kawasaki Connie. (has won manny sport touring contest and is really quick seeing as how you are used to the power of the Busa it won't disappoint you.)
BMW GTL (See Connie)
If you don't mind stepping down the power curve a bit.
Triumph Tiger (underrated and often over looked, but a good bike if your not going WAAAY OFF ROAD)
Suzuki V-Strom 650 a lot of bike for not a lot of coin.
But if you want to go anywhere BMW GS very hard to beat, problem is very tall for shorter riders, vastly different feel from what you have now and very hard to find used because most guys that have them ride off in to the sunset never to be seen until years later!
Just my .05 cents!
Hope this helps.
