Had the stocker front tire and a Pirelli Angel ST on the back (street tires) in this vid... The first time i hit gravel was a "minimum maintenance road" and hit it going 60 by accident because i didn't realize it was there (long story). Anyways i felt the same as you, like the bike would slip out at any minute... Now that i've got a little more seat time, i figured i'd take the V kinda offroadish (tractor path not in that vid) which was pretty tame.. so i said, well if it can handle this, what else can it handle? lol So i ended up taking it on my four wheeler trail and as a long time dirtbiker, was pretty impressed with the V...
That being said... things i'd change:
Un-lower my suspension (bought it that way)
Skid plate + radiator guard
Taller seat for offroad (i have the OEM low gel seat)
Also, if you've never been offroad before i'm not sure i'd recommend it on the V.... lots of torque + street tires= lot's of potential for the rear to kick out.
I was one of those people that said "gravel road maybe, offroad, i doubt the V can do much" but i've been proven wrong
The V is a great little bike, and as Kawasaki intended... you make it what you want it to be... Versatile System=epic win imo
