The V is not the easiest bike to get your knee down for your first time, but it can be done with some commitment.
First disadvantage for a first timer is the seat height and the general height of the bike. Sitting that high makes it feel like you have to lean WAY far over. If you aren't used to getting serious lean then the sensation from the V can be intimidating. So, practice getting low and emulating a racer posture. Its not going to help you if you are sitting all tall in the saddle like the V encourages.
Second is the V has very limited ground clearance. The pegs drag quite early. Sure, that's relative, but compared to any other bike that's designed as more of a sportbike, the V's pegs are low. This means you're really gonna have to hang off. This is also intimidating to somebody who's never touched knee. Its easier to lean a proper ZX over and keep tight to the bike, than hang your body out. Beginners lack the feel for anchoring on the bike let alone hanging off like a gymnast. But it can be done.
Get Lee Parks Total Control book and read over body position and weight distribution. What's awesome is if you have somebody who can video from behind. You'll feel, claim, and think you're hanging off like a loose saddlebag, then you see the video and realize you haven't even moved half a butt cheek off the seat.
I've got my knee down riding cruisers, Bonnevilles, almost a TW200 (oops), a KLR650, and almost all sportbikes. Don't rush into it, take your time and try to learn the correct body position and learn how your weight and angle affect the bike. It looks cool in track day pics, but its nice to also learn why you are doing it too.
