I would like to remove the seats from my 2009 Speedster 150. I have the seat backs off. They just slide up off of aluminum brackets that are pop riveted to the back of the cockpit. There are some plastic standoffs mounted on the back of the cockpit which keep the seat backs from rubbing against the cockpit wall. There is some glue on the brackets which held the seat backs in place. I am interested in removing the seat cushions, i.e. the part you sit on. I saw a page from the shop manual, and it looks like the seat cushions are held in the same way. I have tried pulling the seats forward, and they don't budge. Any help or suggestions would be appreciated.
