The kick stand works fine on my wifes 05' 883 Low with 11" shocks in the rear and the front lowered 1/2" (just sliding forks through the tripple tree 1/2") not sure if the low has shorter kick stand then the standard though?? the stock 883 low shocks are 11 1/2"
I seem to remember that there are different length kickstands from the factory. It looks like the KC part is at least on the right track for you, but I don't like the little end on it. I don't think that it would keep you from sinking into softer asphalt much less dirt. I guess you could call your local dealer and see what the parts guy has for choices.
See if these guys have anything you like: http://www.coolsac.com/
I have an '06 XL1200c...2" lowered in the front and 11" progressive's in the back. I still have the stock kick stand on but I have to be selective where I park. I think I will end up getting a shorter kickstand just for piece of mind.
