Fritz Egli

Fritz W. Egli, (born June 30, 1937, in Zurich) is a Swiss former motorcycle racer.

One of his first vehicles included a Vincent Black Shadow,[1] with what was to become his signature large diameter central tube which won a 1968 motorcycle hill climb championship.

His large diameter tube frame design later incorporated a honeycomb internal section which was suggested by a visiting Australian in 1979.

[2] Egli took the Japanese engines, enhanced them for increased power, then placed them into his own frame designs.

[3] The main backbone pipe of his designs are about 12 cm in diameter and they use straight pipes exclusively, avoiding the "bends and curlicues"[4] of frames such as the Norton Featherbed.
