People spend a lot of money on custom seats but I found that Ultimate BeadRiders made of ceramic for $58 is the way too go for me. It keeps your butt cool and dry and actually even messages at the same time. I have put them on all the bikes I've owned.
I have had beads on my '04 since I got it, with 1,007 miles on the ticker. It now has over 150,000 miles. For me, the pre-2018 OEM seat and beads are great for long distance travel. Then I bought a 2018 Wing. I have had the WingSoft upgrade, with beads the seat still isn't where it needs to be, for me. I think, if the seat is more rigid, like the OEM seat on the pre-2018 bikes are, the beads work better. The 2018+ seat is softer and the beads seem to sink into the seat and take away the benefit. I am going to need to upgrade my 2018 seat if I want more mileage out of a day ride. That is my conclusion, YMMV.
