And ya know... it's worth mentioning that you have to break YOURSELF in too. Last year I rode with my new Corbin/back rest and ended up loving the extra miles I could ride without discomfort. Winter came... and the bike and I became housebound. Then this Spring I rode again and thought, WHAT? The sore butt syndrome returned, until... until I put a few rides under me and now I'm back to luxurious comfort with my Corbie! My point? Ya need to break yourself in, much like a horse rider would have to do the same. Corbin, stock, Mustang or otherwise I believe it's as much physical adaptation as the saddle you sit in.
