It was designer Max Fitz, forbidden by treaty from working on aircraft engines following World War I, who came up with the blueprint for BMW motorcycles that the company follows to this day, 90 years after the first R32 was produced. That first bike featured his now-familiar transverse-mounted "boxer" motor, its twin cylinders jutting out into the cooling breeze. Also present from the beginning was shaft final drive; BMW's attention to engineering and focus on solid build quality was already readily apparent. The R42, introduced three years later in 1926, moved the brand more firmly down the road to profitability and success. Its redesigned and more powerful 500cc engine, now with aggressively finned detachable alloy heads, made the bike a better tourer. With the engine repositioned in the frame for improved weight distribution, stronger, straighter front downtubes could be employed, sharpening the bike's handling. Braking too was improved; gone was the arcane block-and-pulley type rear brake, replaced by a drum on the driveshaft gripped by external contracting bands. Stylistically, the R32's quaint valanced fenders gave way to simpler, more modern looking sheetmetal. Despite the fact that all BMW two-wheelers built up to 1941 owe much to the R42, its production lasted just three years, making this rare Bimmer among the brand's most desirable and sought-after vintage machines. BMW catalogued the R42 for 1.510 Reichsmark.

The first owner purchased this bike 2.6.1928 from BMW dealer Folville & Mettenheimer from Frankfurt am Main. Mr. Ernst Appenheim purchased it in 19.11.83 and started with the complete restoration. Years later this R42 was finish and was ready for road.

This handsome R42 spent his whole life in Germany and comes with Germany papers (copy) of the “französischen Besatzungszone”, original dealer plate of Folville & Mettenheimer, original Bosch lighting set, Bosch horn, Bosch MagDyno, recently overhauled OTA speedo, Lepper seat, many of pic. of the original condition + during restoration and a certificate of the BMW Archiv in Germany. This rare and original flat tank BMW has been produced 2 lasted years and runs great with its 500cc transverse engine.
