I rode a buddy's K75S on some mountain twisties the other day:
and came away with some distinct impressions: first, it is really short after riding a 990. Second, for such a petite-looking bike, the slow speed handling is truly ponderous, but once it gets above parking lot speed, it rides like its on rails. Third, that straight-line stability makes it hard to turn in, but commit to the corner, roll it on, and it completes the turn nicely. Fourth, it reacquainted me with false neutrals.
It was a fun little ride, but I came away a little disillusioned-- I had wanted a ride on that bike for years & it wasn't quite what I was expecting.
