Sat on a Gold Wing and it was fantastic. But as soon as I tipped the bike up off the stand, I knew it felt too heavy for me. YMMV.
BMW K1600GTL had a comfy seat, and felt light enough on a test ride that I believe it would have been a fantastic bike. Just a little outside my price range, though.
HD Electra Glide was very nice.
Victory (I forget which model) was also very nice.
Doesn't expecting the unexpected make the unexpected expected?
