1949 Nimbus Model C

The Danish Model C inline 4-cylinder makes speed easy to obtain but double-declutching is best for a transmission lacking synchronizer rings.

“I saw my first Nimbus in 1974 in Copenhagen,” remembers Allen Siekman. “I was chasing family heritage. The rider had stopped at a traffic light. He was wearing a Barbour jacket and half helmet and goggles, and looked right out of the Thirties. I was mesmerized by the ends of the rocker arms waving at me on the sidewalk.”

In the month Siekman was in Denmark, he was able to watch several more Nimbuses traverse the streets. Many years later, Siekman finally has his own Nimbus. He has found it is as enjoyable to ride as it is to look at.
