I'm looking for a rider's backrest for my 2001 Fatboy. I've tried seats that come with the rider's backrest (both HD and Corbin brand) and I lost legroom on both of them, they moved me forward. I'm now convinced there is no seat that will give me as much legroom as the stock seat so I need a rider's backrest that will work with the stock seat. Anyone know of any? I know a company called Protac makes them and I sent them an email but I'm not sure if they make one for the Fatboy. I've also heard of some bags that fit over the passenger portion of the seat and have a built in driver's backrest, anyone used any of these?
