It took Corbin nearly 4 months to get my seat made and delivered. Arriving today I couldn't wait to put it on the bike. I ask them to make the seat an extra 1/2" higher so I could gain a little knee relief and after sitting on it it does give me a better position over the stock seat. It is at least twice the weight of the stock seat. The seat cowl still fits and allows for installation and removal without any trouble; although the back rest does comes right to the seat end.
