Well that's the reason I decided to modify the original design - to eliminate stresses on the welds.
Basically, what I did was transfer the load of the bike from welds on the guides for the central beam to 2 main vertical sections
(because the guides are no longer welded on sideways but cut into the main sections, and welds are just holding them in place).
And since the lean angle is only 10 degrees, it's enough to keep the stand stable but not enough to stress the welding on the 2 legs down below either.
So the main portion of the load is always on 2 main vertical sections and welds are there just to hold things together.
As you can see from this schematic (that I made from the original one), almost all of the load is on 2 main vertical sections.
A small portion of the load is on the welding where 2 legs meet the main sections but that's about it.
I would comfortably put a bike 2 times heavier than Versys on my stand without any fear.
