FWIW none of mine are semetrical and I have not come up with a reason to need that feature yet.
The home brew R1 and KLR racks and bags ended up being side specific due to the way it had to mount to the bike. Which I'm sure the factories run into the same issue and that is why the factory bags on the KTM and BMW Dakar are both side specific too.
