[QUOTE="LeadHead, post: 183864, member: 367"] I came across a bike today on craigslist called an MZ Baghira 660, a supermoto (or enduro) German bike with a rebadged Yamaha 660 four stroke. I had never heard of the name and I started looking up the company and it's history and I came across a lot of cool stuff about this company that I wanted to share. The motorcycle/auto history is rich in this company's history, and so is the production of the modern 2 stroke (including one of the biggest scandals in motorcycle history) Motorenwerke Zschopau (Zschopau engine factory) is a East German manufacturer located in Zschopau, Saxony. In 1907, the company is founded by Jørgen Skafte Rasmussen as bicycle factory. Later he creates the steam powered car called the DKW (Dampf-Kraft-Wagen: steam-driven car), while the steam powered car was unsuccessful, the company was renamed to DKW. Two-stroke engines are produced starting in 1919, and the first motorcycles are built in 1922. Three years later, the first German motorcycle assembly line was created at DKW in Zschopau. Starting in 1932, the Auto Union is created with DKW, Wanderer, Audi, and Horch. The logo was the four rings that Audi uses today. At the start of World War II, all Auto Union factories are turned over to war-production for the German army. DKW begins manufacturing aircraft components, while the motorcycle department continues to build motorcycles for the army. In 1945, although managing to avoid serious bomb damage, the factory is completely stripped of all it's usable equipment by Soviets in an attempt to cripple any industrial production. DKW's RT125 motorcycle designs were distributed amongst the Allies as war reparations, resulting in the Harley Davidson Hummer, British BSA Bantam, and Soviet's MMZ M-1A Moskva. Motorcycle production starts again in 1946. Then comes Walter Kaaden, the man who will change two-stroke motorcycles. In early 1953, Kaaden has command of the MZ race department. Walter Kaaden was a literal rocket-scientist who, during WWII, helped develop the Hs 293 (radio-guided rocket-propelled missile). After Grand Prix banned superchargers, Kaaden developed MZ two-strokes combining disk valve induction and expansion chamber exhaust. Although the expansion chamber was not technically invented by Kaaden, his understanding of resonance waves led him to create expansion chambers as effective as they are today. The previous expansion chambers were created by Erich Wolf (DKW). Kaaden, using an oscilloscope, examined exhaust resonance waves to create profiles to maximize engine efficiency. The result of this development program was a 125 two-stroke that produces 100 bhp/liter. The engine was later developed to produce 200 bhp/liter in his 1961 125cc racer. MZ's was a great success in Grand Prix racing, leading to East German propaganda and their Communist star; Ernst Degner. Then comes what some call the biggest spy scandal in motorcycle history involving Degner selling MZ secrets to Suzuki: Degner arranged for an escape to the West for his family while he was at the Swedish Grand Prix. He was on his way to winning the 125cc World Championship, but his engine failed early in the race. East Germans then accuse him of deliberately destroying the engine after he had defected to the West. After the race, he got on a ferry to West Germany and met up with his family who had safely defected East Germany. Degner headed for Japan to sign with Suzuki with a head full of MZ secrets. In 1962, Degner won Suzuki's first Grand Prix on a Suzuki that resembled an MZ. In 1983, Degner died under mysterious circumstances. Degner was dependent on medication after a crash that left his body with over 50 skin grafts, and his death possibly occurred due to overdose. Although rumors started, stating he committed suicide or was killed by the East German secret police (Stasi) to avenge his defection of East Germany. :lol: "1983: July, 6th: a ETZ 250 as the two millionth MZ motorcycle leaves the production line 1989: The Berlin Wall falls. 1991: MZ sales drop dramatically, because the old communist market has vanished and the bikes are not attractive enough for the new market. 1992: the MuZ (Motorrad und Zweiradwerk) brand is established.
