Suspension fork
NSU Motorenwerke, 1905

A suspension fork is a type of front wheel guide in the early days of motorcycle development that was offered by NSU Motorenwerke from 1905 to 1909 . Flat springs were attached to the movable fork tubes of the front fork, which were supposed to provide suspension for the fork legs. The first manufacturers of suspension forks were NSU Motorenwerke (model 2.5 HP) and Dürkopp .

Nothing is known about the effectiveness of this suspension fork, at least in 1905 Joachim Albrecht Prince of Prussia made effective advertising appearances for the NSU 2 1/2 with a suspension fork . In 1909, the suspension fork at NSU was replaced by a pushed short swing arm with an auxiliary fork.

Ernst Neumann-Neander took over the construction of the suspension fork in 1923 with his patented suspension fork with the rolling principle . This fork was installed in large numbers on the Opel Motoclub (1928–1930). Erwin Tragatsch considers the "suspension of the front fork with short vertical leaf springs combined in a bundle to be more or less [a] catastrophe". Some authors also classify this fork as a pendulum fork .
