Originally the Rivco stand came with the left side handle/grab rail. Current stand comes with both sides.

I've no trouble putting a Valk on a centerstand, unless the rear is completely flat. Even then, a simple trick and up she comes. It's all in the technique. People tend to yank on the bike and try to pull back on the bars, etc. That just means you're doing it the hard way...or as the snipers say, "You'll just die tired."
Center stand has seriously saved my bacon a couple times...but I do tend to abuse my fat-lady when I'm far and away from homebase. It's a philosophy I suppose...left over from us old-timers that ride 'em hard...and when we tear something up, we get out the kit, put it back together somehow...and ride some more...and just as hard.
I have a lot of trouble imagining a cruiser...or indeed, anything heavy enough that I can't get one end of it off the ground (so I could, for instance, plop it up on a guardrail to work on it) that didn't have a center stand.
This is somewhere in the Yukon...Watson Lake I think...where I ran out of rubber on the back tire. 
I showed up before they opened, pulled the wheel, and when they showed up, handed my wheel to them, pointed at a evil-nasty-bad-flaming-death-causing car tire on the showroom floor, and said, "Put
this, on
there."
Folks in the Yukon are a practical lot. The guy shrugged, mounted the tire, charged me a fist full of rupees, and out the door I was.
Anyway...centerstands. Come to Inzane. I'll show you how.
