I know your main question is Goldwing based, but you did mention you liked riding your RT. My "other bike" is an 010 R1200RT and I'm 6'0". I had to add bar risers and wedges, peg lowering, a LAMM seat rework, and a CALSCI shield to get my C14 as nearly as comfortable as the RT. My size 13's sometimes scuff pavement and the bars still aren't quite where I'd like them, but I'm OK with the compromises, until I 'm ready to spend more money. (maybe them high dollar adjustable bars)
