Welcome to the forum and good luck with your bike search. I suggest you find a seller that has both models and test ride them both.
It's so funny that you mentioned finding a seller with both models, that's exactly what happened! LOL
Two weekends ago I headed out to check out the only used F6B in the Maritimes and it was in Fredericton, New Brunswick, a little under a two hour's drive from my place. It was a beautiful sunny and HOT day!
My son drove me there in his car and I brought my riding gear and a certified cheque from my bank just in case this bike was "the one". The guy let us in his garage and there she sat, a beautiful 2014 F6B in black, just stunning! The bike looked to be in awesome condition. Right next to it was his 2007 Goldwing. I didn't take out the 2007 GW since I had already ridden similar models at the Honda demo days.
He told me that he bought the bike three months prior from the original owner thinking that his wife would like it but she had neck issues and prefered sitting on the 2007 GW with the big trunk, etc... So he decided after a couple months that if she wasn't going to ride with him on the F6B he might as well sell it.
He had all of the maintenance records and receipts that he had gotten from the original owner, an older gentleman who was meticulous at doing his regular oil changes and documenting each one, it's all in a binder too. Other maintenance receipts are in there too.
This is a Canadian bike, so it comes with ABS which I really liked. I can live without cruise control but ABS is a big plus.
It has a TomTom GPS mounted on the left side handlebar and a satellite radio installed on the right side lower fairing. Backrests for both rider and passenger. A center-stand and blacked out highway pegs. There's also a pair of blacked-out floorboards for the passenger included in a box if I decided to swap out the OEM passenger footpegs. The stock windscreen has been upgraded to one with a taller height. There's a pair of air wings under the mirrors to direct airflow towards you or away from you. The orange turn signal lenses behind the mirrors were replaced with smokey ones, looks really cool too.
The milage is 66,000 kms (41,000 miles). It's due for an oil change, and the air filter should be changed soon too. The front tire might have to be replaced before the end of this riding season, the rear tire is better.
He let me take this bike out for a test ride, he suggested a nice long loop around his area, which was in a rural setting. A good 20+ minute test ride was all the proof that I needed to see how great of a bike this is.
So I payed the man and it was a great pleasure to deal with him, real good guy! Funny thing though, when I was starting to weave my way through Fredericton towards the TransCanada Hwy I decided to try out the radio, and guess what was playing..........."Happy" by Pharrell Williams! LOL
I had to crank that sucker up! Now anytime I hear that song, for the rest of my days, I'll always remember the time that I bought this fabulous bike!
I came real close to buying a used BMW R1200RT with trunk and also a BMW K1600 GTL but I'm glad that I went with the F6B. Rock solid reliable.
And while I rode this bike back home I couldn't get over how it drives like a big plush cadillac. Soooo comfortable and tons of power on tap. I should have bought a GW years ago.
Now I have my Vulcan 1600 Classic for sale, I can't go back to that after experiencing this ride!
