c.1970 Kegler 250cc Racing Motorcycle

Aeronautical engineer Horst Kegler founded his eponymous company in 1932 in Nuremberg, subsequently moving to Hilpoltstein after the original factory was destroyed in WW2. Still in business today, the firm specialised in producing high-precision components for the automobile and aeronautical industries. The machine offered here was built to accommodate Kegler's patented 'three-stroke' engine, a hybrid that combined the two-stroke's crankcase induction and transfer ports with the overhead poppet valves of a four-stroke. Patented in the early 1950s and believed built in 1954, the twin-cylinder engine (reportedly one of only two) is housed in a modified Aermacchi Ala d'Oro racing chassis dating from circa 1970. Offered with a display board of information, the machine is presented in racing trim but nothing is known of its history.

As with all Lots in the Sale, this Lot is sold 'as is/where is' and Bidders must satisfy themselves as to the provenance, condition, age, completeness and originality prior to bidding.

Footnotes

c.1970 Kegler 250cc Racing Motorcycle

L'ingénieur aéronautique Horst Kegler a fondé en 1932 à Nuremberg la firme qui portait son nom, puis l'a transférée après la Seconde Guerre mondiale à Hilpoltstein, à la suite de la destruction de l'usine des premiers temps. L'entreprise, toujours en activité, s'est spécialisée dans la production de composants de haute précision pour l'automobile et l'aéronautique. La moto proposée a été construite pour exploiter le moteur "trois-temps" breveté par Kegler, un engin hybride qui associait un carter-cylindres à admission et canaux de transfert de deux-temps à des soupapes-champignons en tête de quatre-temps. Breveté au début des années 1950 et probablement construit en 1954, ce deux-cylindres (réputé n'avoir existé qu'en deux exemplaires) est implanté dans un châssis de course Aermacchi Ala d'Oro modifié, construit vers 1970. La moto, accompagnée d'un panonceau explicatif, se présente en version compétition. On ne sait rien de son historique.

De même que tous les lots de cette vente, ce lot est vendu 'en l'état et à l'endroit où il se trouve' et les enchérisseurs doivent en vérifier la provenance, l'état, l'âge, la complétude et l'authenticité avant d'enchérir.
