Actually, Imthink you'd find it to be pretty comfortable. I don't know what your inseam is, but mine is 32/33" and at 66, I'm comfortable on the Wing. I didn't start feeling my knees object until near the end of a long day ride--250--350 miles. The seat is pretty roomy, and allows a fair amount of room to move around. Add a set of Kuryakyn Ergo highway pegs on the crash bars and you're set up.
I am saying this from my having owned 2 GL1800's. this new F6B is nothing more than a stripped down Gold Wing. The trunk is gone, as is the center stand and reverse, and they put on a shorty shield. The engine is the same,silky smooth with gobs of very tractible power. The transmission has great gearing, but is a bit clunky. The price is similar to that of a Road King, for example, and a bit more than a Nomad or Vaquero. Count on gas mileage to be between 38 and 45 mpg, depending on what your right hand does. A plus is that heat is not a problem with the Wing. I call it a Wing because it is just that--a Wing with different clothes. My here are a lot seat options out there to address things like inseam issues.
