From the very beginning of motorcycles, designers found ways to smooth out some of the bumps in the road. They did this with a primitive front suspension that used springs and rocker arms. The design evolved over the next few decades, but mostly for functionality.

In a post-World War II burst of product changes, Harley-Davidson made the decision to change the front suspension on their largest models, the EL and FL.
The design was an assembly of springs and shock absorbers in telescoping tubes. Hydraulic shock absorbers were not new to motor vehicles, but they would provide a more comfortable ride and improved handling over the previous design.

The update also included the goal of styling the new design for a modern, sleek look.
Brooks Stevens was an industrial designer working in Milwaukee. His notable work included designs in transportation, from automobiles to railroads. Stevens was contracted to style the new suspension, headlight and front fender for Harley-Davidson.

With the new design, the name Hydra-Glide was created for the 1949 model. Referring only to the motorcycle’s front end in the early years, Hydra referenced the new hydraulic shock absorbers and Glide denoted comfort. Later, the name Hydra-Glide was given to the full motorcycle.

The design became a standard for the H-D “big twin” models. In this era, a group of accessories were available for purchase to complement the bike. The “King of the Highway” option group allowed Hydra-Glide owners to easily convert their cruising motorcycle for longer trips.
Touring often meant more luggage capacity and accessories for comfort. Items like luggage racks, saddlebags, a windshield and a tandem seat were part of “King of the Highway.”

According to Mary Ellen, “The whole trip was fun and a complete success. Our Hydra-Glide surely can take it. Its abundant horsepower made for a wonderful, comfortable ride no matter what was in front of us.”

Motorcycle clubs and events were popular prior to World War II. After the war, group riding entered a new golden age, and clubs were busier than ever. The Hydra-Glide served as the motorcycle of choice. Clubs like the Berkeley Tigers of Oakland, California were common riders.

Soon the smooth-riding technology was added to the rear suspension, too. In 1958, Duo-Glide replaced the name Hydra-Glide, reflecting the new front and rear suspension. The following decades continued the naming with Electra Glide®, Street Glide®, and Road Glide® models.
Icons
Harley-Davidson now offers the Icons Motorcycle Collection. Each year, the new model takes direct styling cues, colors, logos and other elements from a historic model.
