On the speedy there is a pull ring that you pull to remove the seat, and the locking mechanism is right about where the end of the america seat would be. How do those who put america seats on speedys attach them? (just the solo part, not the pillion) Does the america seat have the same locking mechanism as the speedy, or if not what muct be done to attach it ? Also, anyone have a corbin america seat and if so how is it as far as comfort compared to the stocker?
