I ride about 25,000 miles per year on loooooong road trips. I've put 10,000 on my C14. I did 1,000 this past weekend. All of it on a the stock seat. I think it rocks...for stocks...

.
The most so far was a trip to Big Bend last month. Did 5 days back to back at 10 to 12 hours per day. Finally on the last day (day 6) I started getting a little sore but nothing really.
BTW...I'm old...bumping 50 and have two grandkids...so it;s not like I'm a young tough rider.
