I've never been a fan of HD - mainly for the poser stereotype that is so strongly represented here in SoCal. That said I know a Korean doctor in Orange County CA that actually rides his HD to Sturgis - respect. I had some time to kill a couple years ago and visited local HD dealer and echo all that Scott wrote above. I sat on the Fat Bob and have to say the quality and materials appear top notch. Have not ridden a HD but doubt I would like all the bulk.
I am looking at bikes again and have to say that the R9T looks mighty tempting. Used copies are hard to come by and they are pricey.
