Jumping from a Harley to a Victory your going to feel like the Victory engine lacks low end torque. A lot of that feeling is gearing (1st gear on my XC is a lot taller than pretty much any other V-twin I've owned) and some of that is the 106" is tuned for midrange power. Let it spin a little bit and it will reward you. If you lug it down around 2000 rpm it won't like it as much as your Harley. It's a different engine feeling and you have to get used to it. But it is also much more powerful & reliable than the HD.
If your the type of guy who likes to push a bike in the twisties the XC will knock your socks off compared to the HD. The handling difference isn't even close. Victory is light years ahead of HD on this.
A Victory isn't ever going to sound like a Harley. If you have to have the "Harley Sound" you probably won't find it on a Victory.
Honestly, the only thing that Harley does better than Victory is dealerships, aftermarket accessories, and paint quality. So if you can live without going to the HOG rallies the XC is a better handling, better performing, better engineered, easier maintenance motorcycle than the Road King.
I'm not bashing Road Kings because they are my favorite HD's. I've had some in the past that I loved. But they don't hold a candle to my XC.
As always, ride one. I don't know of anyone who test drove a XC and came back unimpressed.
