Just uploaded to the Gallimaufry, some notes on the career of one of Germany’s most prolific, and most successful, designers of engines and complete motor cycles. At one point he was responsible for half of all German proprietary engines. In three decades of unremitting work he came up with everything from 50cc tiddlers to the mighty Zundapp two-wheel-drive combos used so effectively by the German army in World War two. Sidevalves, ohv, ohc; singles, twins, fours; two-strokes, four-strokes: Küchen did the lot.
