I'll be 71 in a couple of months, have a 29-30 inch inseam, and have had three total knee replacements (there's a near fatal story there). I have no problem backing the F6B and find it to be easier to back than my Valkyrie was. As stated here by many others, some awareness and planning when parking will prevent any problems. I had always thought, with the Valkyrie, that the day would come when I'd have to move to a smaller, lighter bike. I find the F6B so manageable in parking, backing, etc., that now I may never have to go smaller.
