1958 HARLEY DAVIDSON FL

 

THE FIRST DUO-GLIDE MODEL WITH FRONT AND REAR HYDRAULIC SUSPENSION

1958 was the introduction of the new swinging arm rear suspension, employing a hydraulic shock absorber on each side of the rear frame. A new low profile frame was designed for the rear suspension. AN enhancement of the rear brake was the new hydraulic rear brake unit on the big touring twins. Foot operated, the rear brake responded instantly, smoothly, and positively. Round lucite tank emblems carried over from 1957 sported a new color scheme of gold, silver, and black.
The fins on the cylinder head were increased  to a full inch to allow cooler operating engine temperatures. The pinion gear main bearing and shaft have been increased 1/4in. The bearing consisted of two retainers with 14 1/2in long rollers (instead of one retainer with 13 3/16in rollers). A new exhaust guide on the FL and FLH was made of special alloy steel, replacing the former bronze guides. On the FLH only heavier inner and outer valve springs are employed to ensure positive valve closing and the exhaust valve was made of new material good for higher temperatures. The transmission fourth gear lug engaging face angel was incorporated on the third gear face to permit faster shifting.
A new torrington needle roller cam bearing on the crankcase side of the camshaft was installed. This was the first year for the wide whitewall 5×16 tires to be offered on the Big Twin OHV. The swing-arm frame necessitated redesign of the dual muffler with crossover. The length of the muffler was shortened for less overhang behind the rear wheel. New oil pressure gauge and crankcase breather were adopted.
A break with tradition came with the two-tone color scheme. In the past, the top color on the tanks was the top color of the fenders. The side color on the tanks was the side valance on the fenders. The new Duo-Glide reversed the traditional scheme. The top of the gas tank color was on the side valances of the fenders.

Model was given a new frame in 1958. This frame included a rear swing-arm suspended by a pair of coil-over-shock suspension units. In honor of this fully suspended chassis, the FL's model name was changed from Hydra-Glide to Duo-Glide.

Unlike OHV configuration, aluminum heads, and telescopic-fork front suspension, however, this improvement in technology was applied to the small-frame bikes first, the K-series having received rear suspension in 1952
