Vintage Imperia Model H 1929 500cc One Cylinder Motorcycle Start Up

Fr. Becker’s Imperia factory at Cologne, Kölner Motorrad und Maschinenbau (K.M.B.), initially built 247cc and 347cc ohv Blackburne-engined machines and also versions with the 490cc single-cylinder ohv JAP, but most had Swiss MAG power units of 346cc, 496cc, 596cc, 746cc and 996cc.

The Imperia Python machines were widely used in competition. 1933 saw the introduction of Villiers-engined models of 150 & 200cc. Locally sourced Bark two- and four-stroke engines were employed in several models, and Rolf Schröldter designed a range of new and very unconventional two-strokes./ classic-motorcycle.com

The first was a 348cc double-piston single with the pistons running in opposite directions and a single sparkplug in the centre, based on a Junkers patent. There were really two crankshafts, one on each side of the cylinder. They were connected by a chain and on top was a supercharger.


This Imperia is an older restoration and is fitted with a lighting set + additional Hella headlight, Bosch horn, Bosch MagDyno, B&B Fischer carburetor, Steering damper, Ammeter, Hurth gearbox, original petrol level gauge and with a dealer plate it reads “Bendixen & Lindhard”. This bike with its 500cc ohv MAG engine runs powerful and fine.//classic-motorcycle.com
