Harley-Davidson Baja 100

The Harley-Davidson Baja 100 was a small off-road motorcycle that the Italian firm Aermacchi built for Harley-Davidson, which then owned half of Aermacchi. It was made at the Varese factory and was one of the company attempts to enter the small-displacement off-road market. A 98 cc two-stroke single-cylinder engine with a five-speed transmission was derived from the existing Aletta parts by reducing the bore from 56 mm to 50 mm, and the only purpose-made part was the frame. The first production run began in September 1969, and a team of Baja models won its class in the 1971 Baja 1000, with eight of fourteen entries finishing in the top ten.
