I had one from new speedmaster and I could ride for 80-100 miles before having to stop and walk around...I had Dunnspeed make me one http://www.bonnevilleamerica.com/forums/...p;vc=1&nt=4

I can ride all day on it with no problems...rode to the Laughlin River Run with some Harley riders (baggers) and they couldn't believe that I was running such a low profile seat and didn't have to stop all the time
