AS someone suggested, try Mean City if you want to just get your stock seat modified.
If you want to try a new seat, http://www.ccseats.com/
Talk to Chuck and tell him what your problem is and what you would like.
I have been very satisfied with what they did for me.

 

You,ll get used to it Not that i don,t put a cushier seat on for long trips but it takes some time in the saddle every spring i go threw a painfull period then in a couple weeks starts to fade away.

 

Try a backrest. It makes you sit up and on your azz and not your tail bone. A Corbin seat, backrest and highway pegs fixed it for me.

 

went from seatle washington to pensacola fl with the stock seat. overall mileage was over 7500 miles. i had no and still have no problem with the stock seat

 

Try a Mustang seat with backrest.

 

You might try rotating your handlebars forward to adjust your riding position a little bit. Moving your hips forward with a little bar adjustment can make a big difference, $0.00. The back rest suggestion is good especially if you also suffer from lower back pain, $400.00.

 

I went to a mustang seat that was 1/2 inch wider and about 1 inch taller (thicker) than the stocker and now 400-600 mile days and zero tail bone pain. FWIW.

 

I had the same problem and went to the Reach Seat, the trick is back support. No more problems for me. Good luck with your choice.

 

Backrest & bar adjustment are a big help...you want to be in a good riding position. Also, another vote for Mean City - double memory foam is like sitting on a cloud. They also work the contours so you're not cutting off circulation to lower extremeties...give them a call - much cheaper than new seat.

 

Exact words I was gonna type.
