I spend an incredible amount of time here reading the various threads and I want to thank you guys for: saving me money, costing me money, and tips on just about everything in between. Maybe now I can help someone else.
I couldnt ride more than an hour before I got "bikers Butt" and when I used an Airhawk, it would prolong it but not eliminate it. After a 550 mile ride, I was so sore I could hardly walk. Thats when I isolated the pain to my tailbone.
I'm kind of a do it myselfer so I researched a few webpages and decided what I needed was less padding where my tailbone hits. (I dont want to say "mines bigger than yours, but...). This site I found was invaluable in what I did to "cure" the problem. Link:http://www.diymotorcycleseat.com/
I followed the instructions to take apart the stock seat. I just removed the staples from the riders area as now my wife could have the Airhawk. I found the seat has a very firm base to it with a light pad on top of it. Also it had a very shallow depression in the base where the tailbone would be located. (You cant feel it thru the top layer). I proceeded to get out a Dremel and just made the depression deeper. I added about 1/2 " in depth to it. The cut out area is about 2" wide and 4" long. Dont worry if it looks like a sharp edge in the foam because the top layer wll cover it and smooth it out. Stretch the cover back over it and staple to suit.
To give it a test, we rode 300 miles and i was very surprised that my tailbone didnt hurt. Now I need to put more staples in because I just put in minimal amount in case I had to dig deeper.
I should have taken pictures but the whole job was over in about 45 minutes. There wasnt enough time to think of it.
Total cost for this job was $3.49 for staples. You will want to use 1/4" staples to reassemble.
