Yeah, I bought this bike -GSXS 1000F with the view of using it as a second road bike, got a great deal- 180 miles demo bike for £8000.
I looked at the Superduke but was aware of some problems with this bike and because the nearest dealer to me is an hour away I couldnt do with the hassle and inconvenience, if anything was wrong with it. High speed handling is not supposed to be as good as the F. Also nearly twice the price!
The MT10 looked rather cheap, like the idea of cruise control but again, naked bikes will not handle as well as this bike.
I like the idea of all that midrange and low down power with these bikes, when compared to the F, but thats about it. Dont think you could tour as well on the KTM ( and I would be a little worried with reliability if touring in other countries ), and the yamaha would just have too much windblast.
Once this bike is set up the handling is fantastic, and it could live with anything on the road..
