Yep, this has occurred to me as well. I don't completely lack self control, but even on the FZ I've needed to remind myself to take it easy. The Vstrom makes similar peak hp, but more of it is available down low. I don't know if that will be a good or bad thing in terms of self-preservation. It really does come down to the nut behind the handlebars.All boils down to the HP.....if you're fine with maybe not being able to pull off a chancey triple car overtake on a two lane road, then the 650 will be fine. I deliberately got the 650 because I know I'd not be able to stay off the horsepower if I had a 1000cc bike. It was a decision based upon survival.
