The 280mm mirrors make excellent V-strom mirrors!
They're surprisingly stable and clear for such long mirrors. I see slight vibration where there is a rough spot in the power at just over 3000 rpm. And, as expected, they can't be absolutely clear when off-road. The visibility is perfect for me though. I have them set to see about a lane and a half to either side and also slightly behind me.
Edit: Had to add that Henri (hb7) gets a big thumbs up from me for his service and speed!
