I was newer completely with the original semi-soft original cases. 

They are not water proof, not lockable, and do not stand on the ground without tumbling over. 

The solution is a Givi rack that is installed and removed in two minutes – only leaving small brackets permanently on the bike. 

And a set of narrow, top loading 22 liter cases. 

Right now, I have plenty of parts on the floor 🙂
