the v-stroms don't seem to be massively stable on the front end. I find once any tyre is worn you can no longer ride no handed without it shaking violently. New front has always cured this. Also find the the stroms tend to make a mess of front tyres, they seem to cup the tread blocks, probably what makes it shake. On the plus side it seems to reach an equilibrium and you can run them right out without it getting too bad.
