If you want power/performance, the F6B wins hands down over the Vic. No comparison... off the line, passing ability, etc.
I had a 2012 Victory Cross Country for one year. I purchased it brand new and managed to put 25,500 miles on it during that time. When the bike runs, it runs great... and it's comfortable. Nice seating position, leg room... longest floorboards you will ever find. And storage capacity...WOW...those saddlebags are huge, and I was able to fit all my gear/clothes for two weeks in them without having to mount anything outside (I know how to pack light). HOWEVER...I had A LOT of warranty problems with this bike. This was my first American made bike, and I only purchased it because all my friends who ride Victory swear by them. I was going into more of the touring route for long bike trips, so I wanted a touring bike. I had over eight warranty problems... two of which were replacing the same rear cylinder head that was porous. I had a pulley replaced because it was squealing like crazy, the cruise control module was replaced because it wasn't working properly, corner pieces from both saddlebags were missing, the primary gasket was replaced due to seepage, the rear shock was replaced due to seepage, and the final straw was when I was stranded due to a bad alternator. That was the final straw...I have never been stranded before with any of my prior bikes, and I had just returned from a three day motorcycle trip at Mammoth/Yosemite. I would have ruined the trip for everyone if my bike was stranded during the trip. I could no longer trust the bike, so I sold it, test rode the F6B and was sold.
Parts availability with Victory were a joke. My bike was at the dealer for over 45 days waiting for a rear cylinder head... but Victory was unresponsive with any kind of ETA. Common parts from Victory typically take a couple of weeks to arrive... if they are in stock. Where as Honda... its a matter of days. When I ordered some accessories from Honda, which were backordered...I received my entire order in a week. I was truly impressed.
As others have mentioned... Victory dealers are few and far between. I had to travel approximately 40 miles just to take my bike to the dealer... and they charged me $120/hour to work on my bike. Typical service interval would cost me over $300 each time. With my Honda...I travel about five miles away, and they charge me $80/hour...so my service interval only costs about $150 each time.
In one month, I will have had my F6B for one year... and it's been trouble free.
Now my horrendous experience with Victory could be an isolated incident. The majority of my friends have no problems with their Victories and are super happy. Oh, BTW, the Cross Country... yes... major wind buffeting. I had to switch to a boomerang windshield and add the crash guard covers to prevent the buffeting... but the bike I had was with forged crash bars, which they don't include on the new bikes anymore.
Good luck with your decision...I hope this helps.
