Way better than the factory seat. Fit the bike good. Lot better riding position, and the seat is a lot firmer than factory. The thing I like most about this seat is that it's rounded off and smoother toward the front; makes it a lot more comfortable in the thigh and crotch area.


Seat is beautiful and is a very nice upgrade from the stock seat. My issue and why I'm giving it only one star is because of how it mounts to the bike. The seat's female piece that slides over the Street's mounting bracket at the base of the gas tank is just simply too wide. When the seat is fully mounted and tightened down, there's still about an inch of wiggle room at the bracket. The seat moves from side to side at the base of the gas tank even with the weight of me sitting on it. It could shift mid-turn so I see this as a safety issue and would return it but the return policy on a mounted seat is preventing me from doing that. I'm going to have to do some fabrication to get the seat to mount tightly. In my opinion, this is a design flaw that Mustang should fix.


This is my 2nd Fastback seat, one was on my Nightster and now on my Softail. I really like the quality and durablity of the mustang seats. The comfort level is a big plus also :)

Very comfortable, great seat.


I really like this seat for cruising on my ‘80 FLH. It’s nice and comfy and has a nice lower back support.


love it


It is a really great seat !


The seat definitely looks good. It´s confortable too. Kind of stuck in "one" position. One thing that sucked that there´s a gap between the seat and the fender struts.


The seat is ok. The packaging is a JOKE. After returning the first 2 due to packaging failure in the exact same spot, which damaged the seat, the third one came with the packaging blown out in the same exact spot. Sheer luck it wasn't MORE damaged. After waiting 3 months, I'll take it and deal with the scuffs. Pathetic packaging and to be honest, bad customer service information when I inquired about it. "Oh yes sir the packaging will be corrected for the next shipment." Discouraging.


Great fit, looks really good on sportsters.


Product as described. Less than 2 minutes to install. Comfortable riding solo or 2-up passenger seat width is little narrow, my wife complains that she is slipping as the passenger portion of seat is inclined. I need to get a backl rest probably. Best buy for money.

Looks likes it was supposed to come with the bike. Feels great, looks great.


This was a gift for our son. It was packaged well, easy to install and looks great! Very comfortable, especially on long rides compared to the factory seat. Highly recommend!


Great Seat at a great price, shipped very fast


I replaced the stock seat on my Sportster with this & it was a great move! Not only is it very comfortable but it has cut down on vibration through the seat.

The fastback seat is great, very comfortable, especially on long rides.


Great look.


great seat, easy to install.


The seat was delivered in just a few days. It fit perfectly and looks great. Definitely an awesome upgrade to my bike!


It looks real nice on The Softail Custom but they do not tell you that it raises you up about 2" and me being an even 6'tall its a little hard to put both feet flat on the ground. Its not very soft even though they mention adding extra foam for the comfort, YEA RIGHT. If you want a great look this is for you, you want a great ride than keep looking!!!
