As you may know, if the spring bungs on your chopper frame don’t align with the threaded studs on the bottom of your solo seat, easy installation is practically impossible. Biltwell has addressed this design shortcoming by allowing the carriage bolts on the bottom of this solo seat to slide inside two channels so you can fine-tune their location relative to the bungs on the frame. The Thinline solo seat features a stamped steel pan with raised ribs and Biltwell anvil branding for beauty and strength. Its satin black electroplated finish is both rugged and stylish. The molded polyurethane foam padding is thin yet comfortable, and follows the kicked-up shape of the Thinline pan perfectly to provide support for your backside. This seat is finished off with a heavy duty black vinyl cover.
