Just enough Seat
I have a new 2016 Iron and the new solo seat looked really cool. I would ride for 30 minutes and my tail bone was killing me. I figured I would just get used to it and kept riding.
I rode for over an hour one day in traffic and I thought I would never walk again..
I bought the Mustang fast back seat so my girl friend could get on once and a while to get breakfast or some short trips.
I took off on a 200 mile tripe the other day and had not one issue with the seat.
I only stopped long enough to put the credit card in the gas pump, fill it up and then take off again.
Not sore at all..
The Iron 883 is a very harsh ride, almost a hard tail. The seat allowed me to sit on bike for 3 hours and 200 miles.
Girlfriend says seat is ok but there are times we both come up off the seat on some of the road bumps. But that is the nature of the Iron. I can only imagine this seat on a full travel Sportster would be heaven.

Great looks and great comfort
I have an 2014 883 Iron and this seat fits great. I looked at a lot of seats to add a passenger and they all looked really bulky. My original idea was to just switch it out when I was not riding my daughter on the back but after I installed it it really flowed with the bike well. As far as comfort goes this seat is a huge improvement compared to the factory seat. If you want to add a passenger or just want a good looking comfortable seat I would recommend this to anyone.

Solid seat, not great for 2 up
I'm very happy with the comfort and look of this seat. Just installed it on a '14 HD Iron and it's a HUGE improvement over the stock seat. I like the bobber, minimalist look and so I wanted a seat that would work for occasional 2 up but retained the low profile look. This seat does pretty well from an aesthetic standpoint. But, know that if you're buying this seat it is marginal for 2 up riding. Obviously this seat is not intended for long 2 up trips, but even for short trips around the city, this seat is borderline for the passenger without a solid backrest. So, if you're buying this seat as a great upgrade for your stock solo seat that also has the ability for occasional, short 2-up rides and you're willing to get a backrest for the passenger, this seat comes highly recommended. If your looking for a seat that will work for medium length (30mi+) 2 up rides every weekend, look elsewhere.

This seat is great. I'm a big guy and this seat is very comfortable. It moved me back on the bike at least an inch, but didn't lower my position. The foam in this seat is far superior to stock, it really soaks up what the somewhat harsh Iron suspension doesn't. The passenger section is small but functional. If you ride two up a lot your passenger probably wont thank you. But, if you're like me and don't often have a passenger, it keeps that streamlined look while still giving you the option.

Looks very nice and is very Confortable
This seat is excellent. Is much nicer than the one the motorcycle came with and is very confortable. I love the way the seat feels and it goes perfectly with the bike. I have an 883 and makes it looks so much better.

2016 Harley Davidson Sportster Iron XL883N
Excellent seat
Although I don't have a lot of experience with different motorcycle seats, I can highly recommend this one. I put this on a 2008 Harley Nightster and anyone who knows anything about those bikes knows the stock seat is junk (as well as the suspensions but that is another review). I upgraded the seat first before doing anything to the suspension and it made a huge difference to me in rider comfort. I'd guess the Mustang Fastback moved be back at least an inch or so, and I can't tell if it raised or lower my sitting height...feels about the same. The lower back support - and support during hard acceleration - this seat offers is great, as well as the cushioning....makes the bike feel so much better overall. I don't know why Harley puts such junk stock seats on their bikes. I haven't put a lot of miles on it yet but I have no complaints as it is. Last but certainly not least, it looks killer on the bike. It follows the lines of the bike and bobbed fender nicely. No intentions of riding two up anytime soon so I can't comment on passenger comfort, but I highly recommend this seat for both looks and performance.

Great replacement seat
I bought this seat to replace the stock seat on my 2014 883 Iron and it has made a world of difference in the comfort level of my bike. Price wise, this seat is a bargain compared to a lot of the others that are out there.

The seat is firm compared to some other seats which prevents hot spots that come from sinking into a seat. I appreciated the firmness because it is similar to the saddle on my road bike.

This seat looks amazing on my bike. Besides that it is super comfortable for me. It can improve on the comfort of that passenger though.

I am pleased with this seat
I installed this seat on my 2013 Iron 883. It looks really cool with my sissy bar and back rest. The seat is very comfortable. I may be crazy, but it feels like I am able to lean the bike more easily with this seat than my last one, giving me more control in the turns.

very well manufactured and good materials quality
For the front seat I felt it very similar to the stock one from my Iron 883 2014, nevertheless, seems like my wife on the rear seat didnt like it a lot. So I would recommend it for short trips with a passenger or long solo trips with ocasional company.
