ADDED INFO: The mustang seat has a built in backrest support and will accept any mustang backrest (according to the rep I talked to). Passenger pad is about 1" lower than stock HD, a bit narrower, but comfortable according to my GF. The rear "grab strap" needed a new hole punched to take up the slack. I didn't cut off the extra, but slid it under and beside the seat.

As can be seen, I did manage to get some pictures to accompany this post.

UPDATE, the pictures ended up on the forum photo gallery titled SEAT, not on my profile. Will try to get them there also.


I put the Mustang lowdown on not long after the April purchase of the bike and it much improved my ability to reach the ground. I had heard, but not verified, that the Mustang was 1.5" lower than a 09, but only .5" lower than a 11 with the HD "low" seat, but it felt lower. So with some time on my hands I tried to make as analytical comparison as possible. First riding impression; it lets me flatfoot easily and even some butt airspace when stopped and standing, but I felt it pushed me forward some but not terribly uncomfortably so. With the addition of the Wild1 575 bars, I can sit back more into the backrest and that inproves comfort and backstrain/pain.

Measurements: On the kitchen counter,(Mustang is on right) I set them side by side, same height at the rear mounting lug and front slot. Mustang seat is 1.5" lower. It is a bit forward but the seat back has a curved countour, not straight like the stock HD. I put the bike on the lift, leveled as best I could and made installed measurements. The diminsions shown are not true seat height, but a comparison of the difference between the 2. Level was installed on the seat 10.25" back from the nose of the seat on the HD and 9.5" for the Mustang. Seat back surface contour made the difference. The yard stick was nearly vertical in both and the mounted Mustang seat was 1 5/8" lower.

The seat pans appear to be similar diminsions, I didn't take them apart to do that measurement. Feel free on YOUR seat if you really want that info. The Mustang seat is heavier, the pan/frame much more rigid, and the padding in the nose of the seat similar thickness, although the Mustang has firmer foam. Since the rise, from seating surface to nose is sharper on the Mustang, that likely contributes to the ball cramped feeling for some, but again that was helped for me by sitting back.

Now to see if I can get the pictures installed.

Can't get them to upload so will try to put them on my profile.

 

Great comparison! How would you rate the comfort of the Mustang overall - Thanks

 

I had a Mustang wide touring on my 1600 Kaw Nomad and rated it excellent. I didn't have the stock seat on the current FLHTK for long enough to rate it's ride quality, although it wasn't bad, but it was too high. I was starting to think the low down was a bad decision until I put the Wild1 575 bars on and that changed things for the much better. Still think the Mustang on the Nomad was better, but this is good. Did a couple of 2.5 hour rides this past weekend and only did a brief butt stretch while moving. Mainly for my knee which got replaced a couple of years ago. Bottom line, I am happy and can safely and securely support the bike flattfooted with room to spare. I thought I had more than a 1/2" gain and these measurements validate that feeling.

 

Great post and comparison between the two seats.
I've been considering the Mustang myself because my stock 09 seat is suppose to be 1" taller than your stock seat on the 2011.
Maybe I would get a 2.5" drop from stock with mine......
Great pics , and thanks for posting.

Big difference in the two seats, I have a Mustang Sport touring and love it but could stand it to be a little lower also.
