Great Seat
I installed this seat on my 2011 sportster. I replaced the stock solo seat and have been very pleased. The seat fits pretty well and is very comfortable. Beautiful stitching and clean lines make it very nice.

Nice looking and feeling seat.
I like the looks of the seet and the cushion is very good. If you don't want to be 2/3inches closer to your handlebars then don't buy this seat. If your looking to get a little closer then get this one. Overall it's a very good seat.

Amazing Seat
I picked up this seat for my 2014 Sportster 48. After riding around on the stock seat for a few weeks, I knew right away the first thing to go on the bike was the original seat. After doing a lot of research, I decided to pull the trigger on this seat.

All I can say is "what a great seat from a great company". This seat contours the lines of the Sportster 48 so well. It looks sexy just sitting on the bike. Initial fit and finish along with comfort are great. However, like all new products, it needs to be broken in. Love it so far!

It's the BOMB!
This seat is one of the best seats I have ever purshased. This seat lowers the rider, moves the rider back away from the tank a couple of inches [so your nads don't crush], at the same time giving the rider a great deal of back support and comfort. All this while looking great.

Finally found the one for me
This was the 5th seat I tried for my '05 Sporty, and it is the only one that felt 'just right'. I'm 6'2" and I really wanted to find a solo seat. While this isn't a solo seat, the tapered back gives is a unique appearance for a 2-up, almost with a little cafe racer flavor.

I tried the stock 2 up (felt ok, but ugly), the stock solo (very uncomfortable), the Mustang Vintage Solo (killed my tailbone), and the LePera Bare Bones (great look, but I kept sliding off the back of the seat).

The trick for the Fastback is the back support. It's tall without being too firm (like the Vintage Solo was). Being a fairly tall guy, the riding position is great for my legs with forward controls, but now my bars do feel a little low (stock with 1.5" riser extensions). I think I'll be switching up to some mini apes soon and I'll have found the perfect setup.

Buy one, you'll be glad you did
After over 6 months of frustration working with a Harley Seats custom builder and not getting a seat that fit my Sportster i finally got my $400 refunded and bought the Mustang Fastback seat.

Comfortable is an understatement! Not only is the seat foam plush to sit on, it is so supportive you never feel your bones on the seat pan even after a full day riding. The premium vinyl is that, Premium indeed! Feels almost like riding on leather but no matter how hot the day you dont stick to it like other cheaper vinyls.

I ride a 95 Sporster that i built to be for technical riding Cafe style and the seat looks good. The only thing i would change would be the hight of the lumbar support to be more of a Cafe look but the support is great just like it is. I gets compliments every time i ride on how nice the bike looks.

Wish i would have bought this seat in the first place because it is such a great value and such great quality. I dont think you will find a more comfortable seat at any price. You wont find a better seat company anywhere either. Mustang even allowed me to customise the support bumpers and still honor the full warranty.

Great seat,excellent delivery
Wow. This seat makes a world of difference for a comfortable ride. Some reviews said the it shifted the rider position back an inch. I would say it was more like three. If you are 6 foot plus (as I am), then this seat is all the better for you on a small frame like the Sportster/Nightster. Mustang makes an excellent product.

Mustang Fastback
I am using this seat on a 2005 XL1200 R. This was the best price anywhere, perfect fit, & looks super on the bike. I received compliments last evening from a HD Roadking rider at our Legion Riders meeting. As usual, the service was fantastic from Dennis Kirk, with the fastest shipping around. Thanks

Mustang fastback seat
Seat was installed on a 06 sportster 1200L, fit very good, quality seems very good, comfortable has a flat seating area can move forward and backward the stock seat locked you in one position, seat is slightly taller feels a little better on the hips with the mid. controls than the stock seat did. nice blend of function and style.
