I am in a similar boat. I started riding on an old 1976 Honda CB550. I then bought a 2005 Bonneville and cafe'd both of them somewhat. Now, I have 2 motorcycles and am having visions of a Street Triple in my future. I may be on my way to becoming a motorcycle hoarder.
I don't think I could ever get rid of my old Honda or Bonneville though. I just love the cool factor of the old school looking bikes. But, the Street Triple is my favorite modern bike and I am also a big fan of the Ducati Monster. To me, these are the modern day cafe racers more than the sport bikes.
