BMW R 11
The BMW R 11 was the first touring motorcycle in the 750cc class manufactured by the German Motorcycle with a pressed-steel frame in duplex form, in the vein of the Neander motorcycle of Ernst Neumann-Neander.Thomas Trapp: ''Ernst Neumann Neander und seine Motorräder.'' Bonn 1996, 2. Auflage 2001, , S. 86. 7,500 R 11 motorcycles were produced between 1930 and 1934. History In 1928, BMW presented with the R 11 and R 16, the first motorcycles with a pressed steel frame. In BMW's price lists No. 37 and No. 38 from January and February 1929, the motorcycles were announced for early 1930. The motorcycles were no longer listed in March 1929's price list No. 39. Delivery of the motorcycles first began in Germany in the summer of 1930. Mechanics Engine Its M 56 engine was a four-stroke two-cylinder valve-in-block boxer engine.

Neander (motorcycle)
The Neander motorcycle was designed by Ernst Neumann, who made his name first as a painter and graphic artist, and later turned to motorcycle and car design, going into production in 1928 under the Neander name, and changing his own name to Ernst Neumann-Neander, a doubling of the German and Greek words for 'new man'. Neumann-Neander designed and built a series of unusual prototype and racing motorcycles with lightweight pressed-aluminum beam frames from which the motors hung, and unique pivoting forks that used a spring box near the steering head. In 1926 he founded Neander Motorfahrzeug GmbH in Düren and went into production, using a pressed-steel frame that was cadmium plated instead of his aluminum prototypes. These novel frames housed a variety of motors, from small 122cc Villiers two-strokes to 350cc and 500cc single-cylinder engines by Küchen, to large v-twins by J.A.P. and Motosacoche. The Neander motorcycle had futuristic styling, with a curved, padded leather seat be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Iron
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite.. It is the most common cast iron and the most widely used cast material based on weight.. It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey cast iron's high thermal conductivity and specific heat capacity are often exploited to make cast iron cookware and disc brake rotors. Its former widespread use on brakes in freight trains has been greatly reduced in the European Union over concerns regarding noise pollution. Deutsche Bahn for example had replaced grey iron brakes on 53,000 of its freight cars (85% of their fleet) with newer, quieter models by 2019—in part to comply with a law that came into force in ...

With a total of 136,963 vehicles sold in 2015, BMW registered a growth of 10.9% in sales in comparison with 2014. In May 2011, the 2,000,000th motorcycle produced by BMW Motorrad was an R1200GS. History The company began as an aircraft engine manufacturer in the early 20th century and through World War I. BMW manufactured its first motorcycle in 1923, the R32, which featured a flat-twin boxer engine. BMW Motorrad still uses the flat-twin boxer configuration, but now manufactures motorcycles with a variety of engine configurations. Current production With the exception of the G310 series (which is produced at TVS's Tamil Nadu, India plant), all BMW Motorrad's motorcycle production takes place at its plant in Berlin, Germany. Some engines are manufactured in Austria, Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
