Yes I have read ALL the threads here and am still undecided. Has anyone owned 2 or even all 3 of bikes below for the ultimate comparison

I know any bike will do a rtw trip but I need to get this bit right so have to ask this...

I need a bike for:
1/ Africa trip
2/ south america
3/ general use back in the UK
Riding solo 95% of the time

I've narrowed it down to 3 bikes:

1/ BMW gs650 dakar:
FOR: build quality, comfort, reliability, newer,lighter(?) than my second choice
AGAINST: water cooling vulnerable, EFI too hi tech for field repairs?

2/ BMW r80(r100 bore) G/S mono:
FOR: ...all the obvious reasons posted elsewhere on here!
AGAINST: Is it now just too old and too troublesome to deal with/ reading Grants comments about being best choice twenty years ago but not so now and he should know. I am fairly practical but no mechanic

3/ Honda XRL 650 (haden't heard of till here and desert riders!)
FOR:Honda reliability, lighter than above (it seems)
AGAINST: No idea, hope you will tell me

Even allowing my heart a vote its still such a close call!

thanks guys and I promise to do my turn and answer all the following questioners who suffer the same dilemaI as me

p.s.
I really have spend ages considering and pouring over this site and all its links (great way to spend a few spare days)
