As a total short @rse (I'd struggle to claim 5' 6") I've ALWAYS had trouble reaching the ground on pretty much any bike I've ever owned ..... other than my Ariel Arrow - sorry guys, most of you won't know anything whatsoever about the name or the bike, like me - it's ancient!
Anyway, IMHO, for the most part, managing tall and heavy bikes is a matter of confidence, control and some technique. If you DO need strength then you're in trouble and you're going to be looking for people to help you to pick it up. I know this from considerable experience and a few salutary lessons. I own a 1993 Tiger - you think you've got a challenge?
Try to think and plan ahead on things like parking and turning - it can't always be done but there are often ways to mitigate the need for turning or leaving the bike on adverse cambers. Wherever you arrive, think first about how you'll be departing and try to park accordingly.
I would, personally, avoid altering the bike's geometry just to lower it - unless you have a suspension set-up specialist do it for you - BUT I would definitely
recommend that you have the static sag set up for your weight. You can do it yourself, there should be loads of information on the web (maybe on here, too) about it, but finding a good suspension 'tuner' should be an early port of call for you and should pay its reward in comfort, handling and peace of mind.
Good luck with it and please let us know how you get on.
