Got off my Tenere to test ride one and was instantly surprised with the 'feel' of the size. The 660 actually physically felt bigger to sit on but wow what a difference onroad. The S10 just effortlessly pulls away and sits beautifully on the tar, what a dream to cruise on.
Would i be throwing it around in the bush..no, some do but I see it more as a lazy two-up or fully loaded tourer that I would be comfortable heading down some dirt track to get to a destination.
All depends on your choice of riding I guess.
Still a very big bike that I wouldn't want to be picking up loaded, you would have to plan and execute that recovery carefully or blow out very quickly.
Good luck and keep us updated..
Matt.
