Ernst Degner
Ernst Degner (born Ernst Eugen Wotzlawek on 22 September 1931 in Gleiwitz, Upper Silesia, Germany - died 10 September 1983 in Arona, Tenerife, Spain) was a professional Grand Prix motorcycle road racer from Eastern Germany. Degner was noted for defecting to the west in 1961, taking MZ's tuning techniques to Suzuki, and winning Suzuki's first Grand Prix championship in 1962. Early life and early career Degner's father died just before the end of World War II. Degner, his older sister and their mother fled from their home in Gleiwitz (now Gliwice, Poland) to avoid the advancing Red Army and wound up in Luckau, German Democratic Republic (East Germany) at the end of the war. Degner's mother died shortly thereafter. Degner attended Potsdam Technical High School and was awarded a diploma in development engineering in 1950. He became an apprentice motorcycle mechanic in Potsdam. In 1950, Degner joined the Potsdam Motorcycle Club, where he met Daniel Zimmermann who had built an exce ...

Italian Motorcycle Grand Prix
The Italian motorcycle Grand Prix is a motorcycling event that is part of the Grand Prix motorcycle racing season. From 1949 to 1990 the event was known by the it, Gran Premio Delle Nazioni (''Nations Grand Prix''). It was one of the original rounds of the Grand Prix motorcycle racing calendar. The race was held exclusively at Monza for the first 23 years of its existence. From 1972 to 1993, the event rotated among several circuits and has been held at the Mugello Circuit since 1994, except 2020 in which the race was cancelled due to the outbreak of COVID-19..

Expansion Chamber
On a two-stroke engine, an expansion chamber or tuned pipe is a tuned exhaust system used to enhance its power output by improving its volumetric efficiency. History Expansion chambers were invented and successfully manufactured by Limbach, a German engineer, in 1938, to economize fuel in two stroke engines. Germany was running short of petrol, which was at that stage produced using coal and sewage transformation. An unexpected bonus was that the two stroke engines using tuned exhausts produced far more power than if running with a normal silencer. After the end of the second world war, some time passed before the concept was re-developed by East German Walter Kaaden during the Cold War. They first appeared in the west on Japanese motorcycles after East German motorcycle racer Ernst Degner defected to the west while racing for MZ in the 1961 Swedish Grand Prix. He later passed his knowledge to Japan's Suzuki. How it works The high pressure gas exiting the cylinder init ...

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later t ...

Walter Kaaden
Walter Kaaden (1 September 1919 – 3 March 1996) was a German engineer who improved the performance of two-stroke engines by understanding the role of resonance waves in the exhaust system. Working for the MZ Motorrad- und Zweiradwerk part of the Industrieverband Fahrzeugbau (IFA), he laid the foundations of the modern two-stroke engine. His understanding of gas flow and resonance enabled him to make the first engine to achieve 200BHP/litre with his 1961 125cc racer.''Halcyon days: MZ a potted history'' Alan Turner, Motorcycle Sport and Leisure, No. 577 October 2008, pp114-118 His motorcycle engines were ridden to 13 Grand Prix victories and a further 105 podium finishes between 1955 and 1976.''MZ - the racers'' by Jan Leek, 650 Publications, 1991, Walter Kaaden was born in Pobershau, Saxony, Germany. His father worked as chauffeur to the sales manager at the DKW factory. At eight years old he attended the opening of the Nürburgring racing circuit, a formative event to w ...

Industrieverband Fahrzeugbau
''Industrieverband Fahrzeugbau'' ("Industrial Association for Vehicle Construction"), usually abbreviated as IFA, was a conglomerate and a union of companies for vehicle construction in the former East Germany. IFA produced bicycles, motorcycles, light commercial vehicles, automobiles, vans and heavy trucks. All East German vehicle manufacturers were part of the IFA, including Barkas, EMW (which made Wartburg cars), IWL, MZ, Multicar, Robur, Sachsenring (which made Trabant cars) and Simson. Car production IFA cars were based on pre-war ''DKW'' designs and made in the former Horch factory in Zwickau. The F8 had a two-cylinder engine, and the F9 had a three-cylinder unit. The F8 bodies were straight copies of the pre-war models, and rapidly looked old-fashioned, but some had more modern coachwork by Baur of Stuttgart, then in West Germany. The three cylinder cars (F9) had not got into production before war broke out in 1939, and so had more up to date bodies similar to ...

DKW RT 125
The RT 125 was a German two-stroke motorcycle made by DKW in Zschopau in the 1930s, IFA and MZ in the 1950s and early 1960s, and DKW in Ingolstadt in the 1950s and 1960s. "RT" stands for "Reichstyp" or "National Model". In the 1930s DKW pioneered the Schnürle two-stroke loop scavenging process to dispense with the use of a deflector piston and improve efficiency of the combustion chamber. DKW also developed a highly efficient arrangement of transfer ports. These two features were included in the RT 125 to great commercial advantage. Competitor companies such as Adler and TWN copied the adoption of flat-topped pistons and strove to develop equally efficient transfer port arrangements without infringing DKW's patent. Copies and variants Copies of the RT 125 were built by at least eight different entities in at least six countries. War reparations After World War II the Soviet Union took plans, tooling and even several dozen personnel as war reparations to MM ...

Potsdam
Potsdam () is the capital and, with around 183,000 inhabitants, largest city of the German state of Brandenburg. It is part of the Berlin/Brandenburg Metropolitan Region. Potsdam sits on the River Havel, a tributary of the Elbe, downstream of Berlin, and lies embedded in a hilly morainic landscape dotted with many lakes, around 20 of which are located within Potsdam's city limits. It lies some southwest of Berlin's city centre. The name of the city and of many of its boroughs are of Slavic origin. Potsdam was a residence of the Prussian kings and the German Kaiser until 1918. Its planning embodied ideas of the Age of Enlightenment: through a careful balance of architecture and landscape, Potsdam was intended as "a picturesque, pastoral dream" which would remind its residents of their relationship with nature and reason. The city, which is over 1000 years old, is widely known for its palaces, its lakes, and its overall historical and cultural significance. Landmarks inc ...
