    Sundowner Seat is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Sundowner Seat Great comfy seat. Very secure ride for the pillion. Wife and kids do great on it. Neg ative had to order from shop as very confusing fitment issues relating what sissy bar and backrest will work. Harley should fix that issue on their site.

    Rated 5 out of 5 by from This seat fits great for long rides Didn't care for the seat on the bike. Extra padding makes a world of difference, especially on long rides of a hour or more. Best investment on it.

    Rated 5 out of 5 by from Love this seat! This seat should be standard on the Sportster. Much more comfortable than the stock seat. Easy to install -- took less than 5 minutes. Great product!

    Q & A

    Is the backrest included? Is it a separate piece? Or all one piece?

    Asked by: Vicky6808

    Will this seat fit a 2016 sportster 1200 custom with a 4.5 gallon tank?

    I've heard it would and it wouldn't. I'd really like to buy this seat I love the sundowner seats.
    Asked by: Danmerica
    Hey Danmerica, This Sundowner seat is only validated to fit '04-'06 XL models equipped with 4.5 gallon fuel tank. If you want to go with the Sundowner seat on your '16 XL1200C you need P/N 52000203 and 52400121.

    Passenger Pillion Included in PN 51507-04?

    Can you clarify whether or not the passenger pillion is included in this part number or if it must be ordered separately?
