My versys 1000 is currently the largest bike I own. I sold a v-strom 650 gen1 to make room for it, and they both feel about the same weight. I know that the versys is heavier, but at slow speed, they feel about the same. And once moving, they are nothing alike.
I also have a ktm duke 690, now that is light weight. I had a klx 250 supermoto and the ktm is not much heavier, but sure is a lot more fun !
What I seem to be doing, as sixty is closing in on me, is riding lighter bikes (sold the valkyrie interstate and rune) and wearing a lot more of a lot higher end gear. (leather not mesh, CE armor not foam pads, pants and boots with jacket/gloves)
I believe I'm adjusting the factors in the risk reward equations, I'm reducing risk as much as possible. I maybe reducing the reward somewhat, not as many long trips, no more triple digit rides with sport bikes making crazy passes.
With these adjustments, the equation still works out to "RIDE"
