I can do it with my medium sized bikes, but the ST1100 is a handful.
When we put away the training bikes in our 40' shipping container, we push them in, lower the sidestand and spin them so that they are just past perpendicular with the sides. This allows us to store 15 bikes and other supplies. When we get them out, we just cut left and push and out they come. We can even leave an aisle and get one bike out from in back if we turn them so that they're about 20 degrees past perpendicular. Of course, this is with 125's and 250's.
As a rule, I just back in to a parking place on my own bikes.
