1.5 hours to install a backrest? WOW! That dealer really does pad labor times.

Anybody that's a regular here for over two years knows about my lack of mechanical ability...I have almost none. But even I can install a rider backrest in about 30 minutes.
All you have to do is pull off the seat and install the receptacle for the backrest to slide into. Then put the seat back on and insert the backrest. It's REAL easy!
