My wife complained about my seats so much, I kicked her off and she now has her own ride. Before this, I was switching seats a lot. I did as Dadz suggested and placed the bumper pads on the seat pan itself.
Be careful doing this. The pads get dirt on them so when you mount the seat on the bike, the dirt is wedged between the bumper pad and the paint. Then you and a passenger apply weight and movement which grinds it into the paint job.
I was careful to always wipe down the fender surface and the face of the bumper pads before mounting. I also folder a microfiber cloth longways and placed it between the fender and the seat. This worked well for me.
The bumper kits are about six bucks at the dealer. I kept an extra kit on hand in case I lost a pad. Also a good idea to wipe the seat pan down with rubbing alcohol before adhering the pads.
