'OEC-Anzani' 2,003cc Re-creation
These days the Osborn Engineering Company (OEC) is best remembered for its curious 'duplex' form of steering gear and Claude Temple's world speed record-breaking exploits on the mighty OEC-Temple-Anzani during the 1920s.

The amazing home-made 're-creation' offered here is a masterpiece of modern engineering but without any historical background. Its twin-carburettor, Anzani-style engine incorporates cylinders and cylinder heads machined from solid billet and has bore/stroke dimensions of 105.5x114.5mm for a cubic capacity of approximately 2,003cc. The overhead camshafts are driven by shaft and bevel gears and the claimed maximum power output is 80bhp at 5,000rpm, which is transmitted via a modified Harley-Davidson clutch and a modified Andrews four-speed transmission contained in Harley cases.

This mighty engine is housed in a home-built frame combining lugged/brazed, welded and bolted construction methods, with a wheelbase of 1,280mm. The wheels hubs likewise are to the creator's own design. The machine weighs 325kg (715lb) solo and around 440kg (968lb) as a motorcycle combination, complete with aluminium-bodied single-seat sidecar. In solo trim a top speed of approximately 165km/h (102mph) is claimed in 4th gear at 4,000rpm.

Footnotes

  • De nos jours, l'Osborn Engineering Company (OEC) est restée dans les mémoires pour ses curieux systèmes de direction « duplex » et les records du monde de Claude Temple au guidon de la puissante OEC-Temple-Anzani dans les années 1920. Cette étonnante recréation artisanale proposée ici est un chef-d'œuvre de mécanique moderne, mais dépourvu de tout passé historique. Son moteur type Anzani à deux carburateurs comporte des cylindres et des culasses usinés dans la masse avec des cotes d'alésage et de course de 105,5 x 114,5 mm donnant une cylindrée d'environ 2 003 cm3. Les arbres à cames en tête sont entraînés par arbre et pignons coniques et la puissance revendiquée est de 80 ch 5 000 tr/min, transmise par un embrayage Harley-Davidson modifié et une boîte à quatre rapports Andrews modifiée logée dans des carters Harley-Davidson. Ce puissant moteur est installé dans un cadre « maison » construit par brasage/manchonnage, soudage et boulonnage sur un empattement de 1 280 mm. Les moyeux ont été conçus par le constructeur. La machine en solo pèse 325 kg et près de 440 avec side-car monoplace en aluminium. En solo, une vitesse d'environ 165 km/h est revendiquée en quatrième à 4 000 tr/min.
