I do find all this talk of needing 1 litre for a tour very funny
My first tour round France was done on a £50 off ebay MZ 2 stroke Saxon Tour 300cc
I had an amazing time
admittedly 75-80 was full throttle with a trailing wind
I then got a SV650 - I am 20 stones and had full luggage packed to the brim and tank bag
Still was fastest bike on tour - MZ 660 Skorpion, and 2 BMWs
I travelled round Europe on the SV including over to East Germany and the Netherlands
Never needed any more power at all
In fact those I travelled with were on various old bikes and found my power to be over the top
(The East Germany Trip was in the company of a few 250cc 2 stroke MZs)
The SV was hard work on long distances - my knees and arse basically fell off
I now have a 2010 650 V-Strom
Comfort is fantastic for hours - usually do 8 hour days with a couple of stops in Europe
I presume the new one will be the same
The difference between the SV and Wee is eagerness of bike.
SV was very eager and cruised comfortably at higher speeds
Wee is less eager but actually easier at lower speeds in town
Still comfy at 75-85 and can happily do more if I want
I load the bike lots - so would probably have almost the same weight as you 2 up by the sound of it
hope that helps
