I am not familiar with the Kona frame but wil the above stand mount on it ok? It can clamp to the chain stays behind the bottom bracket or mount on a European style stand mounting plate in the same position.
I just installed one on my Swobo Dixon and while not perfect it is the most stable center stand I have tried other than the Xtracycle & Big Dummy specific Kickback or Rolling Jackass stands. It does need a good application of grease to the leg pivots and cams at the time of installation and a few operation cycles to spread the lube for smoothest operation. When deployed the legs are about 11 inches apart from tip to tip.
