MMW – Tuning parts from a legend from Bavaria

The abbreviation MMW stands for ‘Mangold Maschinen- und Werkzeugbau’. The company was founded in 1985 by Johann Mangold in Aichach, Bavaria, and with his growing fleet of CNC machines, he manufactured individual parts and small batches for two- and four-wheeled vehicles. In 2008, the founder took his well-deserved retirement and his daughter, Barbara Mangold, took the helm of the company. Since 2013, MMW has been based in a larger premises in Kühbach. Many parts are manufactured to customers’ specifications and requirements.
Technical Operations Manager Harald Grillhiesl is passionate about manufacturing scooter parts and is a true authority in the scene. Under his pseudonym ‘Gravedigger’, he shares helpful tips on the German Scooter Forum and delights readers with his dry humour. He regularly presents his own designs to enthusiasts, which enhance existing products from brands such as Smart Carb, Polini or Malossi. Good examples include the Fanwheels and Carburettor Caps. Harald also uses his CNC milling machines to build parts entirely to customers’ specifications or to make practical modifications to existing parts. Either way, the products from Kühbach impress with their outstanding quality and top-class materials, and are often clever solutions to problems that only Harald has identified.
