Over 90,000 miles on my '05 Glide with stock seat(s). I say "seat(s)" because after about 50k miles the original stock seat had holes worn in the outer cover from getting on and off the bike. I purchased another stock seat off Ebay and put it on......same results after 40k. I'm thinking about taking one of them to an automotive upholstery shop and see if they can recover it.....might be cheaper than just keep buying seats.
I've still got the original seat on my '12 Glide and don't currently have any plans to change it out.
