I have an 07 cvo ultra and purchased a heated seat from Corbin last year for it. My wife and I got pregnant and I only put about 400 miles on the seat in 07.
I never rode enough to get the feel of the seat - Everyone told me that you needed to put a 1000 miles on the corbin for it to break in - I just knew that my butt hurt and my wifes butt everytime we got off the bike.
I continued to ride the bike for another 1000 miles this year from April until June - the seat did not change I was in the dealership last Wednesday looking at buying a Zeppellin seat ( I have heard they are the best but they are big and raise you an inch off the bike - I am already on my toes so I cannot go another inch and my bike is lowered) I was telling the parts manager I just can't handle riding on this seat anymore the stock seat hurts after riding a while but the corbin is killing me.
I was at my wits end. I did not want to loose the $1000 I spent on the seat but the brakes and seat are the most important features on a bike for me (of course besides OCD and all the chit I didn't know about until I found this site

)and the seat had to go. Well this weekend my wifes family came to visit (7 women in the house) and I had an opportunity to ride so I rode 700 miles roundtrip to Oregon and back. Somewhere around 300 miles the seat actually became comfortable I cannot explain it but my butt actually fit the seat. It was amazing to me I rode in Hood River on Saturday for about 2 hours and no problems the seat felt great. BUT the true test was the 4 hour trip home I rode almost 400 miles back on Sunday and my butt did not hurt not at all, now my shoulders hurt a little, they always do on a long ride and my lower back hurt a little. I only stopped 3 times on the way home - I rode the first 100 miles through the national forest over Mt Rainier, I was glad I chose the heated option- I took my bike to the dealership to have my heated grips replaced they f*&ed up my grips and did not fix them so I had no heat on my hands but at least my azz was warm - it was slow winding road.
The last 300 miles I rode a combination of highway roads and interstate. The seat felt GREAT! It is still firm but my butt fits the seat the backrest feels comfortable.
If I would have repied last week I would have said from my experience make a different decision than the Corbin but now I would buy another Corbin. I think I just needed to be in the saddle for an extended time really put some miles on the seat - most of the first 1000 miles were just short trips.
Good Luck on your seat. Ride Safe -Tracy
