I have the same concerns. I have even had my dang foot slide when parking and the bike lean over -- it is a terrible load to have to hold up - the bike, me and my wife!!! Well, my answer to - at least some of that - is to have her just get off the bike, then make my turns or back up into a parking space or whatever. I believe RichardS indicated some of the same things. Its just way safer with the wife safely standing there watching rather than sitting on back there while IM doing all the work. I am OK with that - Im not proud - hummmm although there was this one time wayyyyy back in my younger days , I just parked a bike over on its side and reached down to shut it off and left it there - being cool. The parking lot in front of this little dairy queen had just been graveled and man was it thick - the bike just slowly fell over while I was driving it up to the window!!!! I just left it there as if I parked it there!! hehhe
