To conclude the thread, seeing I started it, let me give an update.
I decided to get a CRF 250 Rally. Will help me get back into the biking way, its light, easy to handle (compared to an AT), light of fuel, and if I decide the adventure biking "thing" isn't what I'd hoped it was, will loose less to get rid of it all again.
Did my "first" ride on Sunday morning early(ish) - cool, roads dust free from a light shower on Saturday night. Getting used to the bike jacket was an experience in itself. Really enjoyed the bike even at running-in speeds.
Thanks to all for your inputs, much appreciated.
