    The perfect combination of foam density and shape has resulted in our most comfortable seat for long haul touring. The seat is shaped with a wide seating area to spread the pressure across the broad surface and a narrow nose area to keep your legs together for a shorter reach to the ground.

    • Features a built-in, fully adjustable and removable rider backrest for added support
    • Provides a 5-position height adjustment with 1.5" range, and a wide range of forward/back adjustment with the quick twist of the control knob
    • Backrest pad features a sleek shape that provides full lower back support without pushing the rider forward
    • When combined with the comfortable Passenger Pillion P/N 52000133 or 51770-09 (sold separately), the slim profile of the rider backrest offers the passenger a few more inches of space, and the fold-down design permits easy passenger mounting/dismounting
    • The rich vinyl seating surface is easy to clean and maintain, and features an embossed Bar & Shield graphic on the side skirts
    • Seat width 16.5"

    Signature Series Solo Seat with Rider Backrest is rated 3.3 out of 5 by 3.
    Rated 4 out of 5 by from An upgrade from the stock seat I wanted to upgrade my seat within a week of buying my 2016 Iron. It was just killing me on longer distances.. My local dealer has the seat demo program but has nothing really in a solo sportster line however they did let me order this seat and give it a try before I bought it. That was the only way I would lay down this much cash for a seat. I liked the backrest and found one other similar seat from another company and the price was about the same. It is a definite improvement from the stock. It is a bit wider at the back and has a good feel with the back rest installed. I sit up about an inch higher and further back than with the stock seat. My knee doesn't touch the air cleaner now. The backrest is removable and has 4: vertical positions. The backrest can be adjusted forward about an inch. rather basic adjustments for a seat this expensive. It's a little wider than I like but overall not a bad seat.

    Rated 1 out of 5 by from Far from Perfect Bought this seat because I had a ride of 4000km. I have always had sundowner seats before. I read the write up and thought wow this should be a more comfortable seat, well was I wrong the back rest is very basic the adjuster broke in the first week the seat is worse than sitting on my xr1200 that I had basically it does not conform to your shape at all Maybe this is for someone heavier than me, I am about 200lb very bad choice

    Rated 5 out of 5 by from Great solo seat This seat is great. I was nervous ordering it, but it feels great and the backrest is a game changer. I can really rack up the miles now with the backrest and it comes out super easy

    Q & A

    Does the seat sit high?

    I have a 2017 CVO Street Glide. I love the solo seat it came with as it keeps me further back (I am 6'2", so I like the extra leg room) and low on the bike. Only issue is I have back problems and could really use a back rest for longer hauls, but that seat has no back rest option. I have tried a Mustang seat, but it sat 2 - 3 inches higher than my stock seat. Hated it. The pictures of this seat look like it might be rather thick making for a higher ride as well??

    How does this seat position the rider compared to original seats?

    Specifically how does it position the rider on a 2013 Road King?

    Hi SouthPaul, Because everyone is a little different I would recommend trying this seat out on your ride through our demo seat program. Please contact your local participating dealers to inquire about it. Thank you

    Does the backrest fold forward to make it easier getting on/ off the bike? Thanks
