Tuck n' Roll vinyl upholstery. Direct and hassle-free installation on rubber-mounted Sportsters with stock rear fenders. This deep-pocket style seat offers added back support, great when blasting away at the lights or during a longer cruise. Even your Ol' Lady will like the Mongoose, on shorter trips. Like the other Biltwell seats you'll find a vacuum-formed ABS plastic pan with molded polyurethane foam padding and a hand-sewn heavy-duty black vinyl cover with polyester threads. Note: Will fit 07-09 XL models, but it is required to re-locate the stock ECU / ECM., 04-20 XL (excl. 07-09 XL)
