I ride alot and my factory seat was killing my rear, then I called Corbin and got a custom seat. Oh my God, what a difference. I'm a older guy with a sportbike that after 1000 miles I had to do something. Well, 69,000 miles later and a happy rear, I've couldn't have done it without Corbin. Trust me I ride this thing like a Goldwing and everybody asks, how is this possible and I tell them in one word, CORBIN! Thanks Corbin, you guys are the best!! Hope to get a M109 and when I do, I will be calling you guys.
