I've sat on many bikes and prefer the upright position of the Suzi V-Strom 650, (the one I REALLY want

I can flat foot the V-Strom and have a mature, 38 year old head on my shoulders, (i.e.-I'm not out to set any land speed records), but this will be my first bike. BTW, my first expense is on the MSF course, next on the best riding gear I can find, lastly on the bike itself; right now I'm half way through my second reading of "Proficient Motorcycling".
If my first bike is a Ninja, when I eventually move to the V-Strom, will that change in position be much of an adjustment, or should I learn on the V-Strom?
And many thanks for all the info posted on these different subjects--It has really helped so many people...and probably saved some, too.
