Mit Herz und Seele describes Friedel Münch´s enthusiastic development of motorcycles starting at an early age. After many years of working with racing machinery he designed and produced his legendary Münch Mammoth. His insistence on continuous experimentation was characteristic. This book takes a close look at original projects and never before published plans and drawings. A second special feature of the book is the detailed description of the remarkable URS Project of Helmut Fath, also accompanied by original documentation. Through a series of circumstances this project came into the hands of the Münch enterprise in 1969. The book closes with the development of the Münch Mammut 2000, as illustrated by Thomas Pietsch. Naturally, the book is rich in historic and never before published photographs.
