 The Ner-A-Car was the most successful hub-center steering motorcycle ever produced, with sales far eclipsing earlier or later examples of this design, such as the Yamaha GTS1000 or Bimota Tesi.About 10,000 Neracars were manufactured in the United States by the Ner-A-Car Corporation (under the Neracar name), while around 6,500 are believed to have been produced in England under licence by the Sheffield-Simplex company between 1921 and 1926 under the Ner-A-Car name.Carl Neracher's design had several unusual features, including a low-slung perimeter frame chassis, hub-center steering, all-enclosing bodywork, the feet-forward riding position, and a friction drive transmission, driven by the flywheel of the engine.
