Harley-Davidson launched its first production motorcycle with fuel injection in 1995.
Electronic fuel injection replaced the carburetor on the Electra Glide Ultra Classic for that model year. The system was introduced to improve starting, throttle response, and control of fuel delivery compared with a conventional carburetor.
Harley-Davidson continued offering carbureted motorcycles for a period, so fuel injection did not immediately appear across the entire range. It gradually became more common as emissions requirements, customer expectations, and electronic-engine-management technology developed.
The 1995 milestone refers to factory production, not experimentation or aftermarket conversion. Riders could modify earlier motorcycles with fuel-injection systems, but the Electra Glide Ultra Classic was the relevant production introduction.
