I believe this is a Biltwell Solo Seat. It is in excellent condition. There are some scratches in the paint on the underside.
Per the manufacturer: Our first solo seat is an enduring favorite among vintage and "old-school" motorcycle customizers. Generously proportioned for larger riders, looks great on hardtailed classic big twins.
Technical Details
Heavy-duty stamped steel pan with welded carriage bolts for mounting springs and hinges
Black electroplated finish for classic appearance and resistance to the elements
Precision embossed and hand-stitched vinyl covers in a variety of upholstery patterns
Designed for DIY custom installation only—will not bolt directly to any stock motorcycle
Molded, closed-cell polyurethane foam padding holds its shape and is highly water-resistant
Cover fastened to steel pan with aluminum rivets around the perimeter for rugged durability
Care and Maintenance
This custom motorcycle seat requires basic fabrication and mechanical skills for proper installation. If your motorcycle's frame already has a seat hinge and spring bungs you’re halfway there, but fine-tuning may be required. The heavy-duty vinyl we use on every Biltwell seat is UV- and water-resistant, but their hand-stitched seams are not. Left unprotected in the rain, all our custom seats with upholstery patterns will absorb water.
