Built to mark fifteen years since the Fat Boy arrived in 1990, this anniversary edition took the fuel-injected FLSTFI and dressed it up rather than re-engineering it. It wore chromed solid disc wheels, a gold-plated tank emblem, gold pinstriping on the air cleaner and other covers, and a stitched custom seat. Underneath it was still the 16-inch-wheeled, five-speed Twin Cam Softail of the period.
