Harley-Davidson Duo Glide Motorcycle - Street (1955-1964)

The Harley-Davidson Duo Glide, a pivotal touring motorcycle, was produced from 1958 to 1964. It is renowned for introducing both front and rear suspension to Harley-Davidson's Big Twin lineup, a significant advancement that gave the model its "Duo Glide" name. Prior to 1958, the FL series, known as the Hydra-Glide, featured only front hydraulic suspension. Powering the Duo Glide throughout its production was the iconic air-cooled, 74 cubic inch (approximately 1207 cc) "Panhead" V-twin engine, which had been in use since 1948. The Duo Glide was primarily offered in two trims: the standard compression FL and the higher-compression, more powerful FLH. While the core Panhead engine remained consistent, several enhancements marked its production run. The 1958 introduction brought a swingarm rear suspension, hydraulic rear brake, and a stronger transmission. In 1959, FLH models received a strengthened bottom end and an enlarged oil pump. Minor updates continued, such as external oil lines in 1963. The 1964 model, its final year, featured a new two-tone tank panel and a primary chain oiler, preceding the Electra Glide in 1965.
