I had a mustang seat on my previous bike and wanted to try out the ultimate seat. I ordered the mid rider seat with driver backrest and 12" passenger pillion. it is a bit bulkier than the stock seat but that is to be expected. It fits fairly good, there is a bit of a gap between bike and seat at the bottom of the fender. sitting on bike I am still flat footed I am 5'8", it is a bit wider than stock. i sit higher and a little closer to foot controls. haven't ridden anywhere but down my road and back so i will comment after i put a few miles on it.

 

here are a few pics

 

I have the ultimate seat and rider backrest with passenger pillion and so far so good.

 

My wife had the ultimate seat on her 2009 Heritage and she loved.
