I get the impression you're kinda tall. The windscreen on the V1k will probably buffet you at speed. It doesn't midget me, but it does my wife behind me. I bought a barn door windscreen from Calsci and now she rides in a cocoon too.
One thing I found way different than the FJR or any of my bikes really is that the V1k reacts very quickly to the lightest of touch. Took a while for me to drop old habits and acquire new ones. Honestly, I probably wouldn't have liked it on a test ride. Now, I find it hard to go back. I'll give you some examples.
1. On my FJR and previous bikes, engine braking required throttle blipping when downshifting from higher revs to prevent jerking or even rear wheel lockup. When I first got the V, I could never do the motions fast enough to make it smooth. Then I remembered, this bike has a slipper clutch. Drop the gear down anytime you like and its smooth as silk. Blipping actually creates jerking.
2. There is very little engine braking by comparison to my previous bikes. I'm one who rarely tended to use brakes. I'd always get my setup speed into corners using engine braking. The V just doesn't have it. Now I've learned to trail brake into corners on the rear brake and it works flawlessly. I'm even getting really good using it to tighten up switchbacks in certain intersections that were always tricky.
3. The lighter weight definitely transmits passenger movement into the bike more than heavier bikes. Not sure I ever knew my wife was on the back of the FJR. Her moving around is much more noticeable on this one. If you don't ride with a passenger, this is not a consideration.
One thing I would suggest to you, if you get the opportunity to corner with it is to put it in Low Power Mode (LPM). The throttle response in Full Power Mode is lurchy, which sucks when trying to ride technical stuff smoothly. I've got mine ironed out pretty well with a Power Commander and haven't used LPM since. Before I put the PCV on, I rarely put in FPM. Drove me crazy. Besides, I could ride the bike plenty fast even in LPM.
Enjoy, I look forward to your comments.
