Alright so 2 years ago I blew out 3 discs in my back by being run over by a boat in New Zealand... on the mend finally and after selling my 1150GSA my DR is ready to get out and play... But I'm thinking the seat upgrade will be the critical spring upgrade(IMS tank, new pipe and jetting, aluminum bars and a few more things done a couple years before). Obviously heard the Corbin is the way to go, but looking for any other suggestions before I buy. Thanks and glad to be back in the craziness! Be safe.
