I've had Corbin seats on 4 of my bikes and been happy with all of them. The last was a 2011 Ninja 1000. I would ride it for a couple of weeks, twisties, up hills , down hills, then go back to Corbin and make adjustments. It took 4 trips to make it perfect. I lived in the Bay Area, right below Alice's, so it wasn't that long of a ride down there. Moral of the story, the people at Corbin will do whatever it takes to make you happy satisfied customer.
