Instead of the center stand, you might want the rear lift. I got the Harbor Freight one for about $40 and it works great. The reason is that you don't use a center stand very often, and it saves weight.
I'm not sure, so you probably want to check, if the bike didn't come with a center stand, you might have to modify the cat in order to get it to fit.
I think the reason some models didn't get the center stand was because of the exhaust cat being in the way (I could be wrong, so double check).
