OK, thanks guys. I am going for the adapters, I think I need the maximum room. BTW, I ordered the Sargent seat, and it came in 4 days. However, it was worse than stock. It was torture after 5 minutes. I am returning it tomorrow. So nice that they give a return option. I guess I will have to go with the Corbin. I tested that one at nearby dealer, and it was great. However (long story) one guy didn't know that a bracket had to be removed and was forcing it on (it did not go on - he gave up) and he scratched a protective mat under the seat. I had to make another trip before another guy figured out that the 1st guy did not read the directions about removing the bracket. So, I asked for a discount on the $618 seat, that I will pick up, and they had in stock. The sales guy just said a flat out no way. After having me make 2 trips and messing up a new bike with 50 miles on it, I figured they would be a bit more understanding. So, I will likely get it tomorrow, but give their customer service a bad review.
