I just got a 2011 Nightster. I wanted to add a passenger seat. A guy at work offered me a brand new Mustang one piece seat P/N 75489, but it says it will fit 96-03 models with a 3.3 gallon tank. I have a 3.3 gallon tank, but like I said the bike is a 2011. Will this seat fit? Is there anyway to make it fit? I can get it pretty cheap.

 

Just try it takes two min to change seat

 

I think the ECU, which is under the seat, is going to pose a problem.
