There's no need to do the kick stand mod on any of them in my book. Just put it in gear and roll it forward till all the slack is out of the chain then set it down on the stand. Voila, instant kick stand mod, no Dremel required.
Honestly, this was a bigger issue on the ZRX1200 as the Busa kickstand goes farther past center than the Rex does and this procedure worked perfectly for me for 3 years and has served well so far on the Busa, even parked facing downhill.
As for someone messing with it, I never let my bike out of my sight in public places for very long and if there is people I don't know standing around, not at all.
