Biltwell’s Speedway solo seat fits stock ’04-’06 and ’10-15 H-D XL’s with stock fenders. A clever home builder can get the Speedway seat to fit ’07 through ’09 models, but doing so will require relocating the ECM the MoCo elected to stick in the middle of the rear fender for these model years. Biltwell’s Speedway is constructed from a vacuum-formed ABS plastic pan with molded polyurethane foam padding. It features a hand-sewn, heavy-duty black vinyl cover with polyester thread and plated steel mounting brackets in the nose and tail.
