I do this all the time with the 600 and the Busa

- very handy cos our garage is in the back garden at the end of a very narrow drive - its often better than pushing em backwards forever.
Its easier that it looks once you get passed the FEAR of it all falling on top of you, its all counterbalance stuff so size of bike is not such a big deal.
Once showed my mate how to do this with his Faser as he was complaining about having to make 300 point turns in his garage, when I finished he said - Thats great Bruce but I wanted it facing the other way
I tend to get low and the bike up close to my body/hip/leg when I do it JP not sure if its easier - gonna give a go standing further off as you do and see.
