A Brief History of the Marque
Built in Berlin, these quality machines were made from 1924 to 1933 using mostly watercooled Bekamo-licensed two-stroke engines, although there were some very advanced four-stroke designs with four cylinder OHC engines of 750 and 1000cc. There were also sidevalve shaft-drive flat twins, and late in the game some smaller Villiers-licensed two-strokes.
Founded in 1902* by the Windhoff brothers, the firm manufactured radiators which were installed in many automobiles, trucks and early aircraft. One of the brothers departed and production moved from Rhine to Berlin in 1907.
Windhoff's early two-stroke designs were very successful on the track, winning international races in both the 125 and the 175 classes in 1925.
In 1928 a Windoff 125 established both World Speed and Endurance records on the Opel racing circuit during the annual Opel 24-hour race.
A horizontally opposed twin was introduced in 1929, but the onset of the global financial crisis meant that few were built.
Notes. 1. The firm was established in 1889.
