It's clear the gap is intended, but I don't know why. The spring keeps the stand biased outward in the same way the bike forces the stand to flex when leaning on it.
I'd love to hear why it's designed that way.
The mounting plate on the frame is an even 8.0mm thick. The mounting gaps in both sidestands are 8.35mm. Not as much as I thought, but enough to have a good bit of play.
Just guessing:
option1-: it could add some flexibility to the assembly. So if the bike moves a bit (someone getting on/off it, wind loads...), the system gives a bit, avoiding overloading the bracket itself. When things give a bit, load is better distributed. Very stiff assemblies tend to concentrate loads on very small areas, which could lead to early failure. (imagine wind striking on a bike on the stand: all fatigue loading goes to that bracket)
option2-: perhaps is just to be sure that, even when dirty, there is no stiction in the mechanism, so no matter what, the stand will always retract fully.
option 3-: it was designed like that 50 years ago and it works fine, so it has never been re-engineered. Big tolerances are there by legacy
