So I have a Tall Boy on my 14 SG with a driver back rest. I have had it for a couple of years now say 2-3 and have about 5000 miles on it. I am 6'5'' and 255 and after a 60 mile trip one way yesterday, I notice my butt is going numb even when I stretch out on the highway pegs and its starting to get uncomfortable. So have I worn out the padding or do I need to look at something else that's causing this?
