50th Anniversary of the Sportster
This is the first year of fuel injection on a Sportster. The new Electronic Sequential Port Fuel Injection (ESPFI) included front and rear O2 sensors, Throttle Position sensor, Head Temp sensors, and a fuel pump to allow for closed loop operation. This is the same ESPFI system that prior year model Dyna bikes, with minor tweaks to fit a Sportster.

There was also a special 50th Anniversary edition, limited to 2000 units1). The Nightster model was announced at the Harley-Davidson Winter Dealer Meeting, this new model marked the beginning of the blacked-out themed Sportsters2).
