Vintage chopper dude seat. New old stock.
These are a bit of an odd one. Somewhat universal option for having a slightly longer seat. Pretty customizable mounting.
These have a pivoting 22mm diameter, 145mm long (~5.75" long) seat post in the front. The rear bracket is half removable if needed. The welded portion has 4 mounting holes. The removable portion pivots and also has 4 mounting holes with 3 pre-drilled holes for bolting to your frame. Anyways, lots of options here and even more options if you're willing to modify and get crafty.
Seat itself is nearly 17" long. It is 6.5" wide at the widest portion which is near the front of the seat. The rear of the seat tapers to about 4.5" wide. The seat is 4" thick at the very rear and roughly 3" thick everywhere else.
New old stock but very old. Minor blemishes may be present. The glue is quite old so some fresh glue may be necessary.
Sold as-is. All sales final. No returns.
