excuse my ignorance but you keep using the acronym "S10" is that short for the super tenere?Tube tires and a chain drive.. I would be okay with the chain but tubes suck if you want it for a touring bike. The best bang for your buck in my opinion is the Super Tenere 2014 or newer as you'll get cruise control or the VStrom 650 but the VStrom doesn't have the electrical capacity of the ST or S10 and no CC but both can be had with spoked tubless tires. I don't know much about the crosstourer but the price point has it as very strong competition to the S10.
