I find the stock seat to be very uncomfortable in less then an hour of riding. I am over 60 and have no ass, but I can ride my Superglide for hours. Has anyone drilled the bottom of their stock seat in a pattern to relieve the stiffness of the foam in certain areas? The holes would be 1/2" to 3/4" deep. Any thoughts?
The stock seat uses a rubber foam and I'm not sure how much give you might get from drilling holes in it. But as previously stated, the discomfort is also due to the angle of the seat, canted forward like it is. For me, it was angled enough that I had a pretty good amount of weight/pressure at my wrists and elbows, and like you, I also found the bike pretty uncomfortable, pretty quickly. I had the seat redone, and that helped some, but it didn't fix the bars.
You need support under your thighs to keep the weight off your tail bone, and more evenly distributed on your posterior. Russell Day Long has this formula down to a science, but they are expensive. You could also give Seth Laam a look. He doesn't put suspensions in his seats like Russell, but the shapes of his seats look to me like he understands comfort and support. Good luck with it!
