The SS 350 was the final, enlarged form of the Italian-built Aermacchi Sprint, Harley-Davidson's horizontal four-stroke single. Bigger than the 250 Sprint, it was a light road bike that gained electric start, a fifth gear, 12-volt electrics and a front disc during its life. It was the last four-stroke Sprint, giving way to the two-stroke SS 250 in 1974.
